Jesse Goldberg - ViDA 2020

Jesse Goldberg (Cornell University) Male songbirds turn off their self evaluation system when they perform for females 05-20-2020 Attending to mistakes while practicing alone provides opportunities for learning, but self-evaluation during audience-directed performance could distract from ongoing execution. It remains unknown how animals switch between practice and performance modes, and how evaluation systems process errors across distinct performance contexts. We recorded from striatal-projecting dopamine (DA) neurons as male songbirds transitioned from singing alone to singing female-directed courtship song. In the presence of the female, singing-related performance error signals were reduced or gated off and DA neurons were instead phasically activated by female vocalizations. DA neurons can thus dynamically change their tuning with changes in social context.
