[Possible model of interaction between areas of the cat cerebral cortex]

The effect of neuronal activity of one area in the cerebral cortex on the activity of another area was studied on adult alert cats with algorhythm of estimation of dependence and backward connection. On this basis a structural-functional model was developed of interaction between the visual and somatosensory cortical areas in the periods of aftereffect of repeated photic stimulations. This algorhythm permits to determine quantitatively the weight and direction of the mutual influences of these areas as well as to calculate approximately the volumes of the cellular masses which may participate in the formation of connections between these areas. It is assumed that the model may be used as one of the numerous means of studying the complex pattern of brain structures interactions.
