Inhibition of lobster olfactory receptor cells by an odor-activated potassium conductance.

abstract：:Humans and songbirds shape learned vocalizations during a sensorimotor sensitive period or "babbling" phase. The brain mechanisms that underlie the shaping of vocalizations by sensory feedback are not known. We examined song behavior and brain activity in zebra finches during singing as they actively shaped their song...
