“…The abdominal muscle that showed the lowest correlation with phonatory activity in the present study was the m. rectus abdominis. Activity of this muscle during phonation in man has been observed by Draper et al [2], Hoshiko [3], Hoshiko and Berger [4] and Tomoda et al [7], In the studies of Draper et al [2] and Hoshiko and Berger [4], in which activity of both the m. rectus and m. obliquus externus was record ed, it was found -in agreement with the present study -that the m. rectus becomes active after the m. obliquus externus. Floyd and Silver [ 1 ], in contrast, claim that there is I. VI virtually no activity in the m. rectus during singing.…”

“…These authors agree with the present study that this muscle is active dur ing phonation. Both Draper et al [2] and Hoshiko and Berger [4] found that the onset of m. obliquus externus activity (like that of the m. rectus) depends upon the type of pho nation made. According to Draper et al [2], the louder the phonation, the earlier the on set of activity.…”

“…According to Draper et al [2], the louder the phonation, the earlier the on set of activity. Hoshiko and Berger [4], who asked their subjects to produce the vowel 'a' first in a breathy way and then with a sharp glottal attack, found that muscle activity starts on average 170 ms earlier in the latter case than in the former. In the present study, the m. obliquus externus (like the other ab dominal muscles) showed an earlier onset time for cackling calls than for peep calls.…”

“…In fact, there does not seem to be a single study in subhuman mam mals comparing different respiratory mus cles during phonation. In man, respiratory activity related to phonation has been stud ied using electromyography (EMG) by Floyd and Silver [ 1 ], Draper et al [2], Hoshiko [3], Hoshiko and Berger [4] and Taylor [5]. None of these studies, however, tested more than a few of the relevant muscles.…”

Inorder to find out which muscles are involved in the respiratory component of primate phonation, the activity of 17 abdominal and thoracic muscles was recorded during vocalization in the squirrel monkey. Vocalization-correlated activity was found in the musculi obliquus externus et internus, rectus et transversus abdominis, intercostalis externus et internus and intercartilagineus. It was lacking in the mm. iliocostalis, latissimus dorsi, longissimus dorsi, rhomboideus, serratus posterior superior, trapezius, splenius capitis, sternocleidomastoideus, scalenus medius and pectoralis major. There was simultaneous activation of the rib-raising external and rib-lowering internal intercostal muscles during most vocalizations. It is hence concluded that the intercostals, rather than supporting expiratory efforts, serve to stabilize the thorax, thus providing an anchorage against which the abdominal muscles can act.

The apparently continuous flow of creased from ú200 ms to on average 41 ms during bird song is in reality punctuated by brief periods of minibreaths, again for both species, but inspiratory silence during which there are short inspirations called minibreaths. To determine whether these minimuscle activity did not overlap with that of the expirabreaths are accompanied, and thus perhaps caused, tory muscles. Thus, there was no indication that the by activity in inspiratory muscles, electromyographic inspiratory muscles acted either to shorten the dura-(EMG) activity was recorded in M. scalenus in zebra tion of expiration or to reduce the expiratory effort finches and in M. scalenus and Mm. levatores costas might occur if both expiratory and inspiratory musarum in cowbirds, together with EMGs from the abcles were simultaneously active. Inspiratory and expidominal expiratory muscles, air sac pressure and traratory muscle activities were highly stereotyped durcheal airflow. EMG activity in Mm. scalenus and levaing song to the extent that together, they defined the tores costarum consistently preceded the onset of temporal pattern of the songs and song types of negative air sac pressure by Ç11 ms during both quiet individual birds. ᭧ 1998 John Wiley & Sons, Inc.
