They maintain strict topographical mappings that link corresponding thalamostriatal, striatopallidal, and pallidothalamic projection zones in CM, putamen, and GPi, respectively.261 Moreover, thalamostriatal axons of CM neurons terminate almost exclusively on the spines and dendrites of putaminal MSNs that project, to GPi, while avoiding those that project to GPe.253, The neuromodulatory effects of DA on the integrative activity of striatal MSNs differ considerably for the direct and indirect pathways, due to the dissimilar distributions of d1-like and d2-like receptors on the two types of MSNs.227,270 Multiple studies have shown that substance Pcontaining, GPi/SNr-projecting striatal neurons of the direct, pathway express a preponderance of di-like receptors, while enkephalin-containing, GPe-projecting neurons of the indirect pathway express a higher proportion of d2like receptors227,275-277 despite variable degrees of colocalization of the two receptor types among a subset, of each of the two categories of striatal projection neurons.278, The direct- and indirect-projecting MSNs also differ with respect to their responses to ACh, due to differences in the muscarinic receptors they express.

Introduction Parkinson's disease (PD) is the most common movement disorder of old age (>65 years). However, research seeking to better understand the causes of PD and clinical trials to develop promising new therapies can only happen if people participate in the studies. The recent incorporation of dynamic features of neuronal interactions into the ever more complex functional models of basal ganglia, circuitry317 permits us now to account, for most, if not all of the observed motor dysfunction in PD.

Neuromelanin of the substantia nigra: a neuronal black hole with protective and toxic characteristics. These converging lines of evidence suggest that mitochondrial defects are systemic and causative factors in the pathophysiology of PD, rather than being mere correlates. Nambu A., Tokuno H., Hamada I., et al. With the demonstrable linkage between motor deficits and abnormal oscillatory activity, and growing understanding of how the oscillatory activity arises naturally under conditions of striatal DA depletion, it seems we are approaching the point of having a reasonably comprehensive and testable theory of the pathophysiology of PD. Biology of Parkinson's disease: pathogenesis and pathophysiology of a Recordings in PD patients and primates with experimental parkinsonism reveal low-frequency (4-30 Hz) oscillatory field potentials and rhythmic neuronal bursting in both STN and GPe.298,301,304,305 Neurons in both structures show correlated discharge in the parkinsonian state.306 Effective symptomatic treatment with dopaminergic medication reduces or abolishes the low-frequency oscillatory activity as well as the correlations among neurons.307, STN and GPe have strong reciprocal connections that are functionally antagonistic, the glutamatergic output of STN being excitatory, while the GABAergic output of GPe is inhibitory.

The resulting increase in glutamatergic drive from STN would further increase the activity of GPi/SNr neurons, further depressing thalamocortical activity. Some will likely be incidental to attempts to refine and improve current symptomatic therapies, both pharmacological and neurosurgical, in patients with PD.

Nonetheless, from a large-scale perspective, these same networks can be viewed more simply as an array of contiguous but functionally specialized pathways linking basal ganglia, thalamus, and cerebral cortex in circular fashion to form a corresponding family of parallel, partially closed and largely segregated basal ganglia-thalamocortical circuits or loops.203-207, According to this schema, each loop takes its origin from a particular set of anatomically and functionally related cortical fields (sensorimotor, oculomotor, dorsolateral prefrontal, ventromedial prefrontal, limbic), passing through the corresponding portions of the basal ganglia, and returning to parts of those same cortical fields by way of specific basal ganglia-recipient zones in the dorsal thalamus. Onofrj M., Thomas A., D'Andreamatteo G., et al. In nonhuman primates performing tasks with variable probability of reward, transient deviations in the otherwise monotonous discharge patterns of midbrain DA neurons reflect the subject's realized error in predicting the future probability of behavioral reinforcement.235 Discharge rates of midbrain DA neurons briefly increase when the subject receives positive reinforcement that had not been expected, and decrease when positive reinforcement that had been expected is not received.236 When the primary reinforcement (eg, food or liquid reward) has become associated with a conditioned stimulus, the change in discharge rate will be linked to the unexpected presence or absence of the conditioned stimulus rather than that of the primary reward. Diffusion tensor fiber tracking shows distinct corticostriatal circuits in humans. Such is the case especially for those predisposing factors that may be selective for nigral DA neurons. SNc provides dopaminergic innervation to the entire neostriatum, including the motor territory within the putamen. Studies of MPTP-induced parkinsonism had revealed increased tonic discharge rates in GPi and SNr neurons as well as in STN, and decreased rates of discharge in GPe.186,187,190 This suggested that excessive inhibition of the thalamic targets to which GPi.

The GABAergic neurons of GPe project to STN,271 whose excitatory, glutamatergic neurons send feedforward connections to GPi/SNr to complete one arm of the indirect pathway, and feedback connections to GPe.272,273 A second arm of the indirect, pathway is formed by GPe projections that pass directly to GPi/SNr.269,270 A remarkable consequence of this arrangement is that activation of MSNs associated with either of the two arms will tend to increase neuronal activity at the level of GPi/SNr, in one case by disinhibiting the STN along with its excitatory projections to GPi/SNr, and in the other by disinhibiting GPi/SNr directly.
