[The role of the prefrontal and parietal cortex in learning and memory in monkeys].
Removal of the 7th field of parietal cortex and sulcus principalis of prefrontal cortex did not affect learning processes for images with such properties as spatial frequency, orientation, geometrical form, but worsen learning characteristics in visual differentiation of spatial information making the learning processes unstable, longer and below the 85% level. Removal of sulcus principalis also affects learning of differentiation among various colour stimuli. The short-term memory in these monkeys are also much worse than in intact animals. A scheme of learning involving interacting sensory and cognitive processes controlled by motivation system, is proposed.
