Análisis de los valores de coherencia cerebral intrahemisférica en caninos adultos: Dinámica dual de la actividad eléctrica cerebral

we investigated the intra-hemispheric coherence in the scalp electroencephalogram of 24 adult dogs. in additional way, we have decreed some hypothesis that acquaintance the results and the anatomic connections involved. we worked with 24 healthy adult animals, all of them mayors of 1 year old. all dogs were normal at physic and neurological examination, and none had history of neurological illness. the electroencephalographic record was obtained with a computer electroencephalographic and brain mapping soft, with 12 simultaneous channels of registry. halo (fp-t-o) and dorsal (o-p-f-fp) group of electrode was defined by significant statistic difference. the dorsal group showed a performance in a frequency seems to be placed between theta and alpha band (0 7,58 hz), different to halo group who showed a typical pattern of behavior in the limits of theta band (0 6,63 hz). the phase spectrum show that in the temporal region different pattern of anatomical pathways connect anterior and caudal areas.
