摘要
Dopamine function in birdsong has been studied extensively in recent years. Several song and auditory nuclei are innervated by midbrain dopaminergic fibers and contain neurons with various dopamine receptors. During sexually motivated singing, activity of midbrain dopaminergic neurons in the ventral tegmental area and dopamine release in the striatal Area X, involved in song learning and maintenance, are higher. In this review we provide an overview of the dopaminergic system and neurotransmission in songbirds and the outline of possible involvement of dopamine in control of song learning, production, and maintenance. Based on both behavioral and computational biology data, we describe several models of song learning and the proposed role of dopamine in them. Special attention is given to possible role of dopamine in incentive salience (wanting) and reward prediction error signaling during song learning and maintenance, as well as the role of dopamine-mediated synaptic plasticity in reward processing. Finally, the role of dopamine in determination of personality traits in relation to birdsong is discussed. (C) 2009 Elsevier B.V. All rights reserved.
