Our lab is interested in the neurobiology of visceral sensory integration. Our work deals with a portion of the brain that regulates vital organ function called the nucleus of the solitary tract (NTS). Peripheral afferents from the vital organs (e.g. heart, lungs, gut) directly contact the brain at NTS.

Arterial baroreceptors (BR) encode stretch of arteries with each cardiac cycle. This dynamic information  is transmitted to second order neurons in the NTS. We study these NTS neurons and synaptic transmission in brain slices using dyes to visualize the central terminal boutons of BRs within NTS.
