. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Synchronization in Muscles During Suckling • Thexton and German 253 Swallow Swallow Swallow GH, GG OMO STH HYOG HYOG DIG 1. Time - sec Figure 2. Raw electromyogram (EMG) signals recorded from representative muscles during drinking. In several muscles two sets of electrodes were inserted to establish that the signals recorded were not obviously site dependent within the muscle. Abbreviations used: GH, geniohyoid; GG, genioglossus; OMO, omohyoid; STH, sternohyoid; HYOG, hyoglossus; DIG, digastric; subscript numbers identify two electrodes in the same muscle. All muscles are unilateral. a brainstein pattern generator. Conse- quently, the assumption was that synchro- ny would also be present between coacti- vated muscles during suckling and drink- ing. However, most cross-correlograms be- tween inuscle activities showed no evidence for intraburst synchronization during either suckling or drinking (Fig. 3; Banks and Thexton, 1999). Nevertheless, peaks that were consistent with synchro- nization were evident in the cross-corre- lograins of sternohyoid, geniohyoid, and omohyoid activities, with the cross-corre- lation between stemohvoid and omohyoid in time (t , ) relative to data set 1; again the products of the values in the two series are obtained and summed. In (C), the process is repeated with data set 2 moved back two units back in time (f^s) relative to data set 1. In (D), the process is repeated with a time shift of +1 time units (f, ) and in (E) with a time shift of +2 time units (y. In (F), the sum of cross products (a count of those spikes that coincided at a particular time shift) is plotted against the time shift. In these synthetic data, the maximum correspondence between spikes in the two data sets occurred with a shift of f , . In practice two data sets each at least 15, 000 time units long, containing many hundreds of spike locations, are cross-correlated.. Please note that these im
