• Beyond the reducing valve: towards a computational neurophenomenology of altered states via deep neural networks
  Keisuke Suzuki
  Frontiers in Psychology, 17, Frontiers Media SA, 20 May 2026, [Lead author, Last author, Corresponding author]
  English, Scientific journal, Altered states of consciousness, including hallucinations, psychedelic experiences, and ego dissolution, differ qualitatively, yet no unified computational framework describes what varies and along which dimensions. Computational phenomenology (CP) has emerged as a promising bridge between first-person experience and computational models, yet current formalisations rely predominantly on the free energy principle (FEP). This paper proposes the C × G × D framework, drawing on three functional roles in deep neural networks: a Classifier (C) that extracts features from sensory input, a Generator (G) that synthesises internal representations, and a Discriminator (D) that judges whether a representation originates externally or internally. Phenomenological differences across altered states are redescribed as variations in the objective functions, constraints, and thresholds of these components. The framework reformulates Huxley’s ‘reducing valve’ metaphor: relaxation of C’s constraint exposes normally hidden ‘effective causes,’ producing psychedelic geometric patterns; G’s prior governs hallucinatory veridicality; and D instantiates Perceptual Reality Monitoring. Three hallucination mechanisms—psychedelic, neurodegenerative, and schizophrenia-type—are predicted from distinct parameter configurations. Testable hypotheses derived from iterative-optimisation psychophysics and an extension to ego dissolution are presented. By foregrounding the plurality of objective functions and architectures, the C × G × D framework complements FEP-centred CP and provides a scaffold for translating phenomenology into experimentally manipulable variables., 51596714
• Intentional binding reflects pair dynamics and sense of agency in embodied joint action in human-human dyads but not in human-computer dyads
  Felix Woolford; Keisuke Suzuki
  Frontiers in Psychology, 17, Frontiers Media SA, 12 Mar. 2026, [Last author, Corresponding author]
  English, Scientific journal, Intentional binding has been proposed as an implicit measure of shared sense of agency in joint action, yet it remains unclear whether it distinguishes between individual and different forms of joint control. We compared intentional binding across individual action, human-computer joint control, and human-human joint control in a physically coupled button-pressing task using haptic feedback devices. Binding magnitude was analyzed both intra-subjectively across conditions and inter-subjectively in relation to reported sense of agency and movement dynamics. Contrary to predictions from the we agency literature, we found no intra-subjective main effect of partner type on binding magnitude. However, within human-human dyads, participants who reported a stronger sense of agency exhibited stronger binding effects, corresponding to emergent leader-follower dynamics in their movement trajectories. No comparable relationship was observed in human-computer interactions. These findings suggest that temporal binding effects primarily reflect sensorimotor predictability rather than intentionality or social context per se. While binding alone does not provide a sufficient marker of “human-like” agency in artificial systems, it may reflect the distribution of predictive control within a dyad and thus serve as a quantifiable signature of how effectively partners co-regulate their actions., 33902486

• Real-time fMRI neurofeedback boosts heartbeat perception by modulating insula activation pattern during interoceptive attention

  Imaging Neuroscience, MIT Press, 21 Aug. 2025, [Peer-reviewed]
  English, Scientific journal, Abstract
  
  Real-time fMRI neurofeedback (NF) has emerged as a promising method for enabling individuals to modulate specific brain regions and, consequently, their behavioural outcomes. This study examined whether the NF targeting the right insula could improve heartbeat perception ability and influence emotional response to negatively valenced stimuli, by training participants to modulate the brain activation associated with interoceptive (heartbeat-focused) and exteroceptive (visual-focused) attention. Fifty-four participants underwent a single ~40-minute NF session with contingent (NF group, n = 28) or non-contingent (Sham group, n = 26) feedback, with heartbeat perception and emotional appraisal assessed pre- and post-training. The NF group demonstrated significant improvements in heartbeat perception, with individual learning effects in neuromodulation predicting the behavioural gains. However, group-level NF scores did not differ significantly, likely reflecting variability in learnability. Despite improvements in heartbeat perception, NF training did not modulate emotional responses at either the behavioural or neural level, suggesting that targeting the insula alone is insufficient to alter affective processing within a single session. These findings provide evidence that NF can enhance heartbeat perception through targeted neuromodulation in the insular cortex., 33902486

• The Japanese version of the Phenomenological Control Scale

  Neuroseicne of Consciousness, 2025, 1, Center for Open Science, 22 May 2025, [Peer-reviewed], [Last author, Corresponding author]
  English, Scientific journal,

  People possess the capacity for phenomenological control that enables them to align their perceptual experiences with their intentions and goals. The Phenomenological Control Scale was developed to measure this trait, and we developed and validated a Japanese version of this scale (PCS-J) based on preregistered online surveys (n = 261; retest n = 152). The PCS-J demonstrated sufficient internal consistency and test-retest reliability. Given the known association between hypnotic susceptibility and positive schizotypy, the convergent validity of the PCS-J was supported by a weak positive correlation with positive schizotypy. The discriminant validity of the PCS-J was demonstrated by the absence of a correlation with negative schizotypy. The PCS-J would be useful for research on perception, phenomenological control, and their individual differences in Japanese samples as well as for intercultural studies.

• The Vagus Nerve as a Gateway to Body Ownership: taVNS Reduces Susceptibility to a Virtual Version of the Cardiac and Tactile Rubber Hand Illusion
  Alisha Vabba; Keisuke Suzuki; Milica Doric; Tim J. Möller; Sarah Garfinkel; Hugo Critchley
  Psychophysiology, 62, 3, Wiley, 17 Mar. 2025, [Peer-reviewed]
  English, Scientific journal, ABSTRACT
  
  Transcutaneous auricular vagus nerve stimulation (taVNS) has been shown to influence cognitive and emotional function and enhance interoceptive awareness. This study investigates if taVNS effects extend to the experience of body ownership, as measured via susceptibility to the rubber hand illusion (RHI) in a virtual reality setting. The experiment involved 27 participants who underwent real and sham stimulation in two separate sessions while experiencing synchronous or asynchronous visuo‐cardiac and visuo‐tactile feedback on a virtual arm in place of their own. Results indicated that active compared to sham taVNS decreased sensitivity to the illusion in both cardiac and tactile trials. Specifically, a greater proprioceptive drift difference (PDD) toward the rubber hand was observed for synchronous compared to asynchronous trials only during sham (t(26) = −4.58, p_bonf < 0.001) but not during active (p_bonf = 1.00) stimulation. A similar pattern was also observed for subjective ownership, where synchronous trials led to greater subjective ownership than asynchronous trials only during sham (t(26) = −3.52, p_bonf = 0.010) but not during active (p_bonf = 1.00) stimulation. These findings suggest that stimulation might enhance body ownership, making individuals more attuned to their real bodily signals and less susceptible to bodily illusions. Additionally, physiological measures such as heart rate (HR), heart rate variability (HRV), and skin sympathetic nervous activity (SKNA) were assessed to explore the autonomic effects of taVNS. We observed a decrease in HR during active stimulation (t(26) = 4.30, p_bonf < 0.001), and an increase in SKNA during both sham (t(26) = −4.40, p_bonf < 0.001) and active stimulation (t(26) = −4.85, p_bonf < 0.002). These findings contribute to the understanding of the vagus nerve's role in integrating visceral and somatosensory signals, with implications for clinical applications in conditions characterized by altered interoception and body ownership., 33902486

• Modelling Phenomenological Differences in Aetiologically Distinct Visual Hallucinations Using Deep Neural Networks
  Keisuke Suzuki; Anil K. Seth; David J. Schwartzman
  Frontier in Human Neuroscience, 17, Cold Spring Harbor Laboratory, 03 Jan. 2024, [Lead author]
  English, Scientific journal, Abstract
  
  Visual hallucinations (VHs) are perceptions of objects or events in the absence of the sensory stimulation that would normally support such perceptions. Although all VHs share this core characteristic, there are substantial phenomenological differences between VHs that have different aetiologies, such as those arising from neurological conditions, visual loss, or psychedelic compounds. Here, we examine the potential mechanistic basis of these differences by leveraging recent advances in visualising the learned representations of a coupled classifier and generative deep neural network – an approach we call ‘computational (neuro)phenomenology’. Examining three aetiologically distinct populations in which VHs occur - neurological conditions (Parkinson’s Disease and Lewy Body Dementia), visual loss (Charles Bonnet Syndrome, CBS), and psychedelics - we identify three dimensions relevant to distinguishing these classes of VHs: realism (veridicality), dependence on sensory input (spontaneity), and complexity. By selectively tuning the parameters of the visualisation algorithm to reflect influence along each of these phenomenological dimensions we were able to generate ‘synthetic VHs’ that were characteristic of the VHs experienced by each aetiology. We verified the validity of this approach experimentally in two studies that examined the phenomenology of VHs in neurological and CBS patients, and in people with recent psychedelic experience. These studies confirmed the existence of phenomenological differences across these three dimensions between groups, and crucially, found that the appropriate synthetic VHs were representative of each group’s hallucinatory phenomenology. Together, our findings highlight the phenomenological diversity of VHs associated with distinct causal factors and demonstrate how a neural network model of visual phenomenology can successfully capture the distinctive visual characteristics of hallucinatory experience.

• Hybrid Life: Integrating biological, artificial, and cognitive systems
  Manuel Baltieri; Hiroyuki Iizuka; Olaf Witkowski; Lana Sinapayen; Keisuke Suzuki
  WIREs Cognitive Science, Wiley, 05 Jul. 2023
  Scientific journal, Abstract
  
  Artificial life is a research field studying what processes and properties define life, based on a multidisciplinary approach spanning the physical, natural, and computational sciences. Artificial life aims to foster a comprehensive study of life beyond “life as we know it” and toward “life as it could be,” with theoretical, synthetic, and empirical models of the fundamental properties of living systems. While still a relatively young field, artificial life has flourished as an environment for researchers with different backgrounds, welcoming ideas, and contributions from a wide range of subjects. Hybrid Life brings our attention to some of the most recent developments within the artificial life community, rooted in more traditional artificial life studies but looking at new challenges emerging from interactions with other fields. Hybrid Life aims to cover studies that can lead to an understanding, from first principles, of what systems are and how biological and artificial systems can interact and integrate to form new kinds of hybrid (living) systems, individuals, and societies. To do so, it focuses on three complementary perspectives: theories of systems and agents, hybrid augmentation, and hybrid interaction. Theories of systems and agents are used to define systems, how they differ (e.g., biological or artificial, autonomous, or nonautonomous), and how multiple systems relate in order to form new hybrid systems. Hybrid augmentation focuses on implementations of systems so tightly connected that they act as a single, integrated one. Hybrid interaction is centered around interactions within a heterogeneous group of distinct living and nonliving systems. After discussing some of the major sources of inspiration for these themes, we will focus on an overview of the works that appeared in Hybrid Life special sessions, hosted by the annual Artificial Life Conference between 2018 and 2022.

• Sensorimotor coupling but not visual perspective modulates perceived time during voluntary action
  Shu Imaizumi; Giuseppe Lai; Anil K. Seth; Keisuke Suzuki
  PsyArXiv, Center for Open Science, May 2023
  

  Voluntary actions are associated with both a sense of agency of the action, and with distortions of perceived duration. The present study conducted four pre-registered experiments using virtual reality to investigate whether and how perceived duration and sense of agency during voluntary action are modulated by sensorimotor coupling and visual perspective. Participants performed hand movements while observing a virtual hand moving (a)synchronously with their own hand, estimated the duration of the movements, and rated their sense of agency over the movements. Pre-registered analyses revealed that sensorimotor coupling provided by synchronous visual feedback dilates perceived duration, compared to delayed feedback or pre-recorded feedback of other’s movements (sensorimotor decoupling) in Experiments 1 and 2. Visual perspective (Experiments 1 and 2), anatomical configuration (Experiment 3), and visual eccentricity of the virtual hand (Experiment 4) did not influence duration perception. Sense of agency was also modulated by sensorimotor coupling, suggesting that sensorimotor coupling could be a shared foundation for duration perception and sense of agency. Our findings and the virtual-reality technique we developed shed new light on how humans experience time and self-agency during voluntary action.

  The gap between the Markov blanket and ontological boundaries arises from the former’s inability to capture the dynamic process through which biological and cognitive agents actively generate their own boundaries with the environment. Active inference in the FEP framework presupposes the existence of a Markov blanket, but it is not a process that actively generates the latter.

• More than meets the heart: systolic amplification of different emotional faces is task dependent.

  Cognition & emotion, 35, 2, 400, 408, Mar. 2021, [Peer-reviewed], [International Magazine]
  English, Scientific journal, Interoceptive processes emanating from baroreceptor signals support emotional functioning. Previous research suggests a unique link to fear: fearful faces, presented in synchrony with systolic baroreceptor firing draw more attention and are rated as more intense than those presented at diastole. This study examines whether this effect is unique to fearful faces or can be observed in other emotional faces. Participants (n = 71) completed an emotional visual search task (VST) in which fearful, happy, disgust and sad faces were presented during systolic and diastolic phases of the cardiac cycle. Visual search accuracy and emotion detection accuracy and latency were recorded, followed by a subjective intensity task. A series of interactions between emotion and cardiac phase were observed. Visual search accuracy for happy and disgust faces was greater at systole than diastole; the opposite was found for fearful faces. Fearful and happy faces were perceived as more intense at systole. Previous research proposed that cardiac signalling has specific effects on the attention and intensity ratings for fearful faces. Results from the present tasks suggest these effects are more generalised and raise the possibility that interoceptive signals amplify emotional superiority effects dependent on the task employed.

• Intentional Binding Without Intentional Action
  Keisuke Suzuki
  Psychological Science, 30, 6, 842, 853, SAGE Publications, Jun. 2019, [Peer-reviewed], [Lead author, Corresponding author]
  English, Scientific journal, The experience of authorship over one’s actions and their consequences—sense of agency—is a fundamental aspect of conscious experience. In recent years, it has become common to use intentional binding as an implicit measure of the sense of agency. However, it remains contentious whether reported intentional-binding effects indicate the role of intention-related information in perception or merely represent a strong case of multisensory causal binding. Here, we used a novel virtual-reality setup to demonstrate identical magnitude-binding effects in both the presence and complete absence of intentional action, when perceptual stimuli were matched for temporal and spatial information. Our results demonstrate that intentional-binding-like effects are most simply accounted for by multisensory causal binding without necessarily being related to intention or agency. Future studies that relate binding effects to agency must provide evidence for effects beyond that expected for multisensory causal binding by itself.

  Nature-Inspired Computing Design, Development, and Applications, 232, 254, IGI Global, 2012, [Peer-reviewed], [Lead author]
  English, In book, In this paper, the authors study the emergence of homeostasis in a two-layer system of the Game of Life, in which the Game of Life in the first layer couples with another system of cellular automata in the second layer. Homeostasis is defined as a space-time dynamic that regulates the number of cells in state-1 in the Game of Life layer. A genetic algorithm is used to evolve the rules of the second layer to control the pattern of the Game of Life. The authors found that two antagonistic attractors control the numbers of cells in state-1 in the first layer. The homeostasis sustained by these attractors is compared with the homeostatic dynamics observed in Daisy World.

  English, Scientific journal, The effect of shapes on self-movement has been studied with an extended model of autopoiesis. Autopoiesis is known as a theory of self-boundary maintenance. In this study, not only the autopoietic generation of the self-boundary, but also the emergence of self-motility, has been examined. As a result of computer simulations, it has been found that different membrane shapes cause different types of self-movement. A kind of chemotaxis has been observed for some shapes. The mechanism of chemotaxis is discussed by studying the internal chemical processes within the shape boundaries.

  English, Scientific journal, Life as an autonomous homeostatic system is discussed. A mechanism that drives a homeostatic state to an autonomous self-moving state is examined with two computational cell models. The mechanism is met with Ashby's ultrastability, where random parameter searching is activated when a system breaks a viability constraint. Such a random search process is replaced by the membrane shape in the first model and by chaotic population dynamics in the second model. Emergence of sensors, motors and the recursive coupling between them is shown to be a natural outcome of an autonomous homeostatic system.

  English, Scientific journal, We study a system of self-replicating loops in which interaction rules between individuals allow competition that leads to the formation of a hypercycle-like network. The main feature of the model is the multiple layers of interaction between loops, which lead to both global spatial patterns and local replication. The network of loops manifests itself as a spiral structure from which new kinds of self-replicating loops emerge at the boundaries between different species. In these regions, larger and more complex self-replicating loops live for longer periods of time, managing to self-replicate in spite of their slower replication. Of particular interest is how micro-scale interactions between replicators lead to macro-scale spatial pattern formation, and how these macro-scale patterns in turn perturb the micro-scale replication dynamics.

  サリエンスという言葉には多義性がある。かたや「知覚サリエンス」では知覚的に周りと比べて目立つという特性を表しており、かたや「動機サリエンス」では物体に情動価を付与させる働きとして捉えられている。本論文では「知覚サリエンス」と「動機サリエンス」との関係を明確にすることを目的とする。このことは精神医学において提唱されているASHを精緻化できるという貢献があることが期待される。精神病症状の異常サリエンス仮説aberrant salience hypothesis of psychosis (ASH)は精神病症状の発達から回復までを整合的に説明したものとして重要性が高い。しかし重要な問題点としてサリエンスという言葉が曖昧だという点がある。そこでこの論文ではまず現状でのサリエンスの定義を明確にするため、知覚サリエンスと動機サリエンスに分けて考える。そしてこのサリエンスをアフォーダンスとして捉える考え方がふたつの方向性 (心理学の哲学と情報理論的な脳のモデル(能動的推論))から支持されることを示す。このような視点からサリエンスを捉え直すことで、サリエンスはepistemic affordance, exploitive affordance, aversive affordanceに分類できる。このようにサリエンスを捉え直すことによって、ASHはより精緻なものとできる。つまりASHにおいては、epistemic affordanceとaversive affordance両方の亢進を考慮する必要がある。ここで前者は対象への接近を動機づけるが、後者は対象の回避を動機づける。このようなコンフリクトが患者を苦しめ、なんらかの認知的な解決を必要とする。このことはASHでの「サリエンスの誤帰属」という言葉からは見えてこない。最後に以上のことと脳部位との対応について議論し、さらに本論文で提案される考えの応用範囲について議論する。, 126–141, Japanese, Technical report

  令和5年度は、初年度に開発したボトムアップ処理を中心とする深層学習モデルを拡張し、重ね合わせ原理を用いた感覚統合を行うニューラルネットワークモデルを用いて、感覚入力のトップダウン的解釈を与える認知モデルを開発した。このモデルは、予測符号化理論に基づいており、感覚入力に対する予測と予測誤差の最小化を通じて、感覚情報の統合と解釈を行う。また、ラバーハンド錯覚のシミュレーションモデルを利用し、自分の身体領域を道具の先までに拡張するシミュレーションモデルを構築した。トップダウン的解釈を可能とする認知モデルにより、道具使用時の触感覚を道具不使用時の自分の身体の触感覚へと同等に重ね合わせることに成功した。
  近接領域での手を用いた作業や振る舞いの経験が錯覚に与える影響を調べるため、実環境での、視覚、触覚、運動データの計測準備を進めた。協力者の頭部にカメラを固定し、作業時の画像を視覚データとして取得し、手にはデータグローブを装着し、触覚データと運動データを収集するこれらのデータは、初年度と2年目に行ったシミュレーションと同等の実環境データとして活用される。トップダウン的解釈を可能とする認知モデルとシミュレーション・物理環境において収集したデータを用いて、深層学習で実装した認知モデルを学習させた。ラバーハンド錯覚のシミュレーションにおいて、錯覚を再現することに部分的に成功しており、今後の更なる改善が期待される。
  本研究の成果は、国際学会で発表し、高い評価を得ている。トップダウン的解釈を可能とする認知モデルの開発と、シミュレーションデータを用いた学習手法について、論文を執筆しており、国際学術誌に投稿する準備を行った。令和5年度の研究により、トップダウン的解釈を可能とするモデルの開発とそれらを用いた認知モデルの学習が進展した。

• 脳状態可視化に基づく内受容注意モニタリングシステム開発とマインドフルネスへの応用
  科学研究費助成事業 挑戦的研究(萌芽)
  Jun. 2022 - Mar. 2025
  小川 健二
  本研究は、被験者自身の内受容注意に関わる脳活動を可視化して本人にフィードバックすることで、効果的な脳のセルフコントロール・システムを提案する。身体内部からの情報を伝える感覚(内受容感覚)は、特に感情・情動やメンタルヘルス等との関連が示されている。マインドフルネスでは、現在の自分の身体内部感覚（呼吸や心拍）に注意(内受容注意)を向ける (body scan)ことで、外的なストレスへの 効果的な対処を図っており、心理臨床現場でもその効果が実証されている。しかし運動訓練等とは異なり、内受容注意の程度、すなわち自身の脳活動変化を観察することはできないため、どのような方略を取れば効果的であるのかが明確でないという問題点がある。そこで本研究はリアルタイムfMRIを使い、内受容注意時の自身の脳活動を可視化し本人にフィードバックすることで、自身の脳状態を把握した効果的な脳のセルフコントロール・システムの開発と応用を目指す。本提案では脳の島皮質に着目する。島皮質は大脳皮質が島のように内側に折り畳まれている箇所であり、視床から内臓感覚などの身体内部に関する感覚(内受容感覚)を前頭葉へと中継する場所である。またfMRIを使った研究からも、内受容注意により、島皮質の活動が増加する点が明らかになっている。実験では、被験者にMRI装置に横たわった状態で内受容注意課題を行ってもらう。具体的には、軽く目を空けた状態で自分の現在の身体感覚(呼吸や心拍など)に注意を向ける。その際の島皮質の活動をfMRIで計測し、その結果を本人に対してリアルタイムで棒グラフや数値等で分かりやすく視覚呈示でフィードバックする。
