Method Fluorescent labeling of HVC Neurons
Comments HVC (High Vocal Center) includes two projection neuron (PN) types, one (HVCRA) that innervates the song premotor nucleus RA, and another (HVCX) that provides auditory and song motor-related input to the anterior forebrain pathway (AFP), a striatothalamic circuit necessary for audition-dependent vocal plasticity in adult zebra finches.
