Local inhibition shapes afferent excitatory drive of output neurons in the songbird basal ganglia network

Abstract

Background Song learning in songbirds shares striking similarities with speech acquisition in humans. Songbird brains contain a neural network dedicated to song learning, called the anterior forebrain pathway, which is homologous to the mammalian basal ganglia (BG)-thalamo-cortical loop. A structure called Area X contains both striatal and pallidal components of the BG circuit and projects to the medial portion of the dorsolateral nucleus of the thalamus (DLM), where pallidal cells make powerful GABAergic synapses that could drive firing through postinhibitory rebound mechanisms. We aim to determine the transformation undergone by input signals through avian BG.
