Top-Down Control of Sweet and Bitter Taste in the Mammalian Brain

Highlights
Sweet and bitter are represented in the brainstem by genetically distinct neurons
SST+ and CALB2+ neurons in the brainstem carry bitter and sweet signals to the cortex
Feedback from bitter cortex amplifies bitter but suppresses incoming sweet taste signals
Cortical feedback via amygdala ensures bitter-evoked behavioral aversion remains robust
This project used the UltraMicroscopeII Light Sheet Microscope for imaging brain cleared using the CUBIC protocol.
