  Scientific journal, ABSTRACT
  
  Although extracellular field potential changes are commonly observed in the nervous system, it remains controversial if extracellular electrical activity contributes to neural processing or whether it is an epiphenomenon associated with neural activity. We previously reported that the extracellular field potential change in compound eyes in response to light stimulation induces firing rate changes in olfactory sensory neurons in female Drosophila melanogaster . Through further investigation, we found that the extracellular field potential within the olfactory sensillum is regulated by octopaminergic neurons in response to light stimulation and that rhodopsin 7 mediates the firing rate changes in the olfactory sensory neurons in response to field potential changes in a light‐independent manner. Structural analysis suggests a voltage‐dependent gating mechanism for rhodopsin 7 to respond to the field potential change. This study reveals that the nervous system actively controls the field potential in response to sensory input, resulting in the alteration of behavioral patterns as well as neural firing patterns in a context‐dependent manner.

  Scientific journal, Abstract
  
  The ability to learn from past experiences to inform future decision making is crucial for humans and animals alike. One question with important implications for adaptive decision making is whether we learn about the absolute values of cues we encounter (how good or bad?) or about their relative values (how much better or worse than the alternative?). Humans have been shown to use relative value learning, even when it leads to suboptimal decisions. In this study, we ask whether insects employ absolute or relative value learning. Using the larvae of the fruit fly Drosophila melanogaster, we designed associative odour–taste learning experiments to distinguish both kinds of learning and found that larvae learn about the relative rather than the absolute values of both rewards and punishments, irrespective of the number and sequence of training trials. This suggests that relative value learning is a facility shared across the animal kingdom from maggots to humans and can be accomplished even by small insect brains. Given the potential of D. melanogaster as a model organism for in-depth neurobiological analyses, our study opens up an opportunity to reveal the detailed mechanisms underlying relative value learning.
