vocalizations without temporal and/or spectral distortions could be consistently elicited at low threshold currents ( typically below 10 microa ) within three clearly circumscribed brainstem areas , namely , the deep layers and ventral parts of the intermediate layers of the superior colliculus ( sc ) , the deep mesencephalic nucleus ( nmp ) in the dorsal and lateral midbrain reticular formation and in a distinct area medial to the rostral parts of the dorsal nucleus of the lateral lemniscus .
