2002). 19). This pattern of interdigitation of terminals from distant and separate cortical regions is another indication of the fundamentally associational character of the prefrontal cortex.  Efferents In accord with an almost universal law of cortical connectivity, the prefrontal cortex sends fibers to practically every structure from which it receives them. Furthermore, the distribution of efferents generally conforms to the topological order of afferents, and a remarkable degree of mutual correspondence can be observed, at least in primates, between different prefrontal fields and the structures with which they are connected.

1980). , 1997). , 2002, 2004; Morrison and Baxter, 2012). Because of their importance for neuroplasticity and cognitive function, two agerelated morphological alterations appear critical: (1) a decrement in synaptic contacts; and (2) a decrement in axonal myelin. The age-related decrement in synaptic contacts is the subject of a review by Morrison and Baxter (2012). The emphasis of the review is the progressive loss of thin dendritic spines observed as a function of age in the pyramidal cells of the prefrontal cortex of aging monkeys.

The connectivity within and between parietal and temporal regions has also been further clarified; on the basis of connective patterns, the superior temporal sulcus appears to be a region of polymodal sensory convergence in the posterior brain (Mesulam, 1981; THE PREFRONTAL CORTEX 36 2. 16 Stepwise projection of connections originating in the somatic, visual, and auditory areas of the monkey’s cortex. Each step is shown by a dotted pattern, and the succeeding regions of termination by a pattern of horizontal lines.
