For example, certain brain regions, such as the (4), cognitive abnormalities can be identified during the medial temporal lobe (including the hippocampus, amyg- prodromal phase of the illness and in those at increased dala, and parahippocampal gyrus), the superior temporal risk for the disorder (5), cognitive symptoms appear to be gyrus, the dorsal prefrontal cortex and the thalamus, have persistent across the course of the illness (6), and the severity all been shown to have reduced total volume in subjects of cognitive impairment may be the best predictor of long- with schizophrenia, although the magnitude of the decrease term outcome (7,8). Thus, the clinical features of schizo- and its consistency across studies has not been uniform (25). Although some of the reported findings cannot be Clues from Developm ental Features accommodated in this way, a number of the affected regions Although the idea that schizophrenia is a late consequence share reciprocal connections. Thus, pathophysiologic of an early developmental lesion (9) has many merits, direct models that account for the reported abnormalities in two evidence for a brain abnormality that could be explained or more of these regions, and the connections that link by a mechanism operating prior to or at the onset of the them, may be particularly promising. For example, reports of cytoarchitectural Research Strategies for Identifying disturbances in the entorhinal cortex of schizophrenic sub- Neural Circuitry Abnormalities jects (10,11) attracted a great deal of attention because the reported findings were strongly suggestive of an abnormality Based on the three types of clues summarized in the preced- in neuronal migration (12); however, subsequent studies ing, one can ask whether they converge or triangulate on with larger sample sizes have both failed to confirm these neural circuit(s) that may be preferentially involved in the reports and have provided likely methodologic explanations pathophysiology of schizophrenia.

In addition, a recent gene schizophrenia perform poorly on cognitive tasks that involve expression profiling study using cDNA microarrays found working memory, the ability to transiently maintain infor- that the group of genes encoding proteins that regulate pre- mation in order to guide a subsequent response (27).

Consistent with these observations, subjects with For these reasons, the next two sections of this chapter schizophrenia also fail to show normal activation of the focus on a summary of the normal organization of dPFC dPFC when attempting to perform tasks that tap working circuitry and on a review of the evidence suggesting that memory (30). Second, from the developmental perspective, the circui- try of the primate dPFC clearly undergoes marked refine- ments during adolescence, although certainly some other OVERVIEW OF DPFC CIRCUITRY IN brain regions that have not been as well studied are also PRIMATES likely to show such changes. For example, the number of excitatory synapses in the dPFC declines by 50% during Direct studies of the circuitry of the human dPFC have adolescence in both monkeys and humans (31,32). In addi- obvious limitations; however, the available cross-species tion, substantial changes occur in markers of excitatory, in- studies indicate that the macaque monkey brain provides hibitory, and modulatory inputs to pyramidal neurons in an accurate and useful model system for understanding the deep layer 3 of primate dPFC.

Thus, this section ficity of at least some of these changes raises the possibility reviews the constituent cell types and the patterns of intrin- that circuits involving these pyramidal cells may be preferen- sic and extrinsic connectivity that characterize the primate tially affected in schizophrenia (33). Third, from the perspective of regional brain analyses, the PFC has been shown to have subtle reductions in gray Cell Types matter volume in a number of structural imaging studies Pyramidal Neurons of schizophrenia (25). The failure of other studies to detect such structural abnormalities in the PFC has been hypothe- About 70% of all cortical neurons are pyramidal cells (51).

In addition, some (38–40), but not all (41), in vivo pyramidal neurons. Because dendritic spines are actively proton spectroscopy studies indicate that N-acetyl aspartate formed or resorbed in response to changes in presynaptic (NAA), a putative marker of neuronal and/or axonal integ- inputs, dendritic spines provide a good estimate of the num- rity, is reduced in this brain region. Interestingly, the magni- ber of excitatory synapses that pyramidal cells receive (52). In addition to receiving one excitatory during working memory tasks, raising the possibility that input, some dendritic spines also receive a synapse with a neuronal abnormality in the dPFC could account for dis- the features suggestive of an inhibitory input. Inhibitory tributed functional disturbances in the working memory terminals also synapse on the dendritic shafts, cell body, and network (40). Typically, pyramidal Other lines of evidence suggest that these changes may cells receive about 2,000 inhibitory synapses on dendritic reflect disturbances in the synaptic connectivity of the dPFC shafts, 200 on the cell soma, and 20 on the axon initial in schizophrenia. For example, the presence of decreased segment (53). Schematic drawing illustrating the characteristic morphologic features of pyrami- dal neurons in different cortical layers. Note that the laminar location of the cell soma tends to be associated with the major projection target of the principal axon. The axons of pyramidal cells typically give rise to intrinsic primate neocortex (55), and are comprised of about 12 dis- collaterals, which travel either horizontally or vertically tinct subtypes (56,57).

The axon characterized by pleomorphic vesicles in the axon terminal terminals of these neurons, which are arrayed as distinct and symmetric pre- and postsynaptic densities. Layer 1, which is located just below the pial surface, contains relatively few neurons, but approximately 90% of these neurons utilize GABA. Layers 2 and 4 are thin and densely packed with small 'granular' cells. The majority of these neurons are small pyramidal cells, and GABA neurons constitute approximately 30% and 15% of all neurons in layers 2 and 4, respectively (55). Layers 3 and 5, the thickest cortical layers, contain prominent pyramidal neurons with a classic morphology. In both of these layers, the size and packing density of the pyramidal neurons is greater near their borders with layer 4. These patterns make it possible to subdivide layers 3 and 5 into superficial (to- ward the pial surface) and deep zones. Pyramidal cells in layer 6 have a modified or atypical appearance. In general, GABA cells constitute 20% to 30% of the neurons in layer 3, and about 15% of the neurons in layers 5 and 6 (55).
