    Abstract:
    The multiunit activity in the frontal and sensorimotor cortex was recorded by the bundle of nichromic electrodes in waking cats with different levels of alimentary motivation. Interaction between the neighbouring and distant neurons was evaluated by means of statistical cross-correlation analysis of spike trains. It was shown that the 24-hour food deprivation increased the number of correlations between discharges of the neurons both in the local (between the neighbouring neurons in the frontal and sensorimotor areas) and distributed networks (interarea correlations between the frontal and sensorimotor cortical neurons) with delays in the range of 0-100 ms. This increase was most significant in the delay range of 0-30 ms.
