THE COMPUTER-SIMULATION OF PRIMATE (MACACA-MULATTA) SPATIAL VISUAL DELAYED-RESPONSE AND CEREBRAL PREFRONTAL CONTROL FUNCTION

Cerebral prefrontal function is one of the important aspects in neurob iology. Based on the experimental results of neuroanatomy, neurophysio logy, behavioral sciences, and the principles of cybernetics and infor mation theory after constructed a simple model simulating prefrontal c ontrol function, this paper simulated the behavior of Macaca mulatta c ompleting delayed tasks both before and after its cerebral prefrontal cortex being damaged. The results indicated that there is an obvious d ifference in the capacity of completing delayed response tasks for the normal monkeys and those of prefrontal cortex cut away. The results a re agreement with experiments. The authors suggest that the factors of affecting complete delayed response tasks might be in information kee ping and extracting of memory including information storing, keeping a nd extracting procedures rather than in information storing process.
