[The hypothesis of the cortical mechanisms of operative memory]

The investigation of neuronal activity of monkey cerebral cortex during delayed spatial choice performance allows to develop a hypothesis about the neuronal networks securing the operative memory. The work of one of them is based on the relay-race and reverberation principles of information transfer. Another neuronal network secures the reliability of the transfer phases of behavioural program. Both of these neuronal networks are represented differently in the prefrontal and parietal associative cortical areas.
