The neuroscience of emotion and temperament in primates

Research Summary

In the Fox lab, we want to understand the neurobiology of “affective style”. We want to understand why some people are afraid to leave the house, while others enjoy the feeling of danger. We want to understand why some people callously abuse, while others become overwhelmed with empathy. We hope that understanding the biology of affective style will lead us to a better understand humanity and help people make choices about who they want to be.

Much of our research aims to understand the biology that underlies dispositional anxiety. This kind of understanding could allow for specific interventions to ameliorate anxiety disorders and reduce the suffering of anxious individuals. To do this, we use varied tools to study humans and nonhuman primates, including: high-throughput computing, neuroimaging, RNA-sequencing, cellphone-based experience sampling, and designer receptors exclusively activated by designer drugs.

The Fox lab for Translational Affective Neuroscience aims to foster principles of innovation, integration, and collaboration in conducting rigorous and open science.
