lateral magnocellular nucleus of the anterior nidopallium (LMAN)

E675118

The lateral magnocellular nucleus of the anterior nidopallium (LMAN) is a key forebrain song-control region in songbirds that contributes to vocal learning and variability by providing instructive signals to motor song pathways.
