About me

I am the group leader of the neurobiology of positive emotions research group at the department of neuropeptide research in psychiatry. My research investigates the neural mechanisms underlying positive emotional states, particularly playful behaviours in rodents. Through the integration of in vivo electrophysiology, behavioural analysis and comparative approaches across species, my work seeks to shed light on the mechanisms by which positive emotions are generated in the brain. This contributes to a more comprehensive understanding of affective processes that are relevant to mental health.
 

Shimpei is currently the group leader of the Neurobiology of Positive Emotions research group and has been awarded the Japan Neuroscience Society's Young Investigator Award (JNS).
