[Characteristics of the activity of prefrontal cortex neurons during spatially delayed reactions in the monkey].

On the basis of unit activity in the cortex around sulcus principalis during the spatial delayed response, several types of neurons were distinguished in monkeys. The number of different neurons varied in different parts of the cortex. Determination of some factors affecting the activity of these neurons and comparison of data on their quantitative distribution in the anterior, medial and posterior parts of the cortex around sulcus principalis with the available behavioral data obtained with restricted removal of the same brain areas, lend support to the assumption that the neurons attributed to different types are responsible for a variety of processes and represent various functional units.
