[Mechanisms of coding the configuration of a tactile stimulus by cortical neurons]

Data obtained by recording single neuronal pulse responses in the fourth layer of somatosensory cortex were compared with those on simulation of coding by cortical neurons of the pattern of tactile image. The results of the simulation indicate that some parameters of tactile stimulus are encoded by the pulse pattern, whose form depends upon the actual spatial form of the tactile stimulus. A study of a neuronal network simulating interaction of cortical neurons in the first somatosensory area has shown that a neuronal network can filter "blot" and "band" configuration.
