Learned vocalizations (long call and song) of adult male songbirds start from the high vocal center (HVC), and are integrated and output by the robust nucleus of the arcopallium (RA), which connects synaptic relationships with the dorsomedial nucleus of the intercollicular complex (DM). To determine the effect on learned vocalization of the unilateral forebrain and midbrain in adult male zebra finch, electrolytic lesions and acoustic analysis technology were used. The results indicated that RA and DM nuclei are involved in the control of learned vocalization, and the right side is dominant in the forebrain and midbrain.
