Sensitive response to low-frequency cochlear distortion products in the auditory midbrain.

abstract：:The execution of action sequences is the basis of most behavior. However, little is known about the neural foundation of visuomotor sequence execution in birds, although pigeons are a classic model animal to study sequence learning and production. Recently, we identified two structures in the pigeon brain, the nidopal...
