[ 6 ] [ 7 ] In HVC, neurons switch from responding best to tutor song (35–69 days post-hatch) to responding best to the bird's own song (>70 days post-hatch). [ 8 ]
Birds acquire some pigments, such as carotenoids, by eating fruits, seeds, or insects. Carotenoids produce the bright reds, yellows, and oranges seen in birds, and they are the same pigments that ...
HVC is located in the caudal nidopallium.It projects to the song motor pathway via the robust nucleus of the arcopallium (RA) and to the Anterior Forebrain Pathway via the basal ganglia nucleus Area X. [1] It receives recurrent motor activity through the thalamic nucleus Uvaformis (Uva) and input from the auditory system through projections from the caudalateral mesopallium (CMM) and through ...
