Syringeal EMGs and synthetic stimuli reveal a switch-like activation of the songbird’s vocal motor program
The coordination of complex vocal behaviors like human speech and oscine birdsong requires fine interactions between sensory and motor programs, the details of which are not completely understood. Here, we show that in sleeping male zebra finches (Taeniopygia guttata), the activity of the song syste...
