[Afferent cortico-cortical connections of the orbito-frontal cortex].
Relations of frontal and orbital sections of the prefrontal cortex with different sections of neocortex were studied in cats by means of acute strychnine neurography. Afferent cortical connections of orbital and frontal sections did not differ much in their organization. Both sections had direct efferent cortical connections with motor, somatosensory and the rostral sections of the secondary auditory zone. Primary auditory field, visual and parietal associative cortex of suprasylvian gyrus had no direct afferent connections with orbito--frontal cortex. The cortico--cortical connections of orbito--frontal cortex with motor, somatosensory, and rostral sections of insular zone of neocortex appeared to be bilateral.
