Interaction of short latency cortical responses to somatosensory and acoustic stimuli in anterior part of middle suprasylvian gyrus of cat's brain.
The work sums up the results of experiments in which interaction was studied between cortical short latency nonprimary responses (SNPR) produced by paired stimuli in the anterior part of the middle suprasylvian gyrus of cat's brain. In paired stimuli (somatosensory + acoustic or acoustic + somatosensory) the second stimulus (test stimulus) followed after the first stimulus (conditioning stimulus) in intervals of 20 to 400 ms. An analysis of the results demonstrates that in an animal anaesthetized with Nembutal (35 mg/kg) an interaction takes place between central systems taking part in the origin of acoustic and somatosensory SNPR in the anterior part of middle suprasylvian gyrus. On the basis of these data the authors conclude that acoustic and somatosensory SNPR in the anterior part of middle suprasylvian gyrus result from the activity of two different and independent systems.
