Increased GABAergic striatal input to GPe will reduce the latter's tonic GABAergic suppression of STN activity, allowing the oscillatory potential of the reciprocal antagonism between GPe and STN to be expressed.317 Accompanying the increased release of GABA at striatoGPe synapses will be a corresponding increase in the release of colocalized enkephalin.256,318 Local diffusion of enkephalin within GPe will lead to presynaptic suppression of GABA release not only at the striatoGPe terminals themselves, but also at the sites of local GABAergic feedback from neighboring GPe neurons318; the net effect, of this reduced lateral inhibition will be enhanced synchronization among the GPe-STN projection cells.317. Purba JS., Hofman MA., Swaab DF. Depletion of striatal DA in human PD and in the nonhuman primate model of MPTP-induced parkinsonism is associated with specific changes in neuronal activity patterns in the motor circuitry of the basal ganglia, including increased rates of neuronal discharge within the main output nucleus of the basal ganglia, Gpi, and in the STN, and minimally decreased discharge in the globus pallidus pars externa (GPe).186-188 Administration of dopaminergic agents results in normalization of neuronal activity and reversal of motor impairment.188,189 Fiber-sparing ablation190 or muscimol-induced inactivation of STN191 reverses the motor deficits of monkeys made parkinsonian with MPTP.

Although the striatum does receive limited extrinsic input, from the cholinergic PPN,58,280 by far the largest source of striatal ACh is the intrinsic population of large, aspiny interneurons.281,282 Unlike putaminal MSNs, these large interneurons are spontaneously active and they do not discharge in relation to specific parameters of movement preparation or execution, such as direction or force, although they do show selectivity for the mode of movement guidance (eg, self-initiated versus visually guided versus memory-guided).283 Rather, they discharge briefly and synchronously following the presentation of a conditioned sensory stimulus that signifies the imminent, delivery of a reward.284,285 In this respect, their behavior is similar to that of nigrostriatal DA neurons.

More than one million people in the United States are living with the neurodegenerative ravages of Parkinson's disease. Colosimo C., Hughes AJ., Kilford L., Lees AJ. This may account in part for the lack of effective neuroprotective strategics in human PD, as these can only be tested in subjects if they already have the disease.182,185 Nonetheless, until we are able to intervene directly in the neurodegenerative process by blocking one or more of the implicated pathogenic pathways, the causative role of these mechanisms in human disease will remain uncertain.

This type of signal has been used successfully in certain types of adaptive neural networks that, incorporate an adaptive critic to support autonomous learning.237 In an analogous manner, by encoding such a signal, nigrostriatal DA neurons could play an important role in learning by broadcasting the optimal times at which striatal synapses should be strengthened or weakened.

Parkinson's disease (PD) is a progressive neurodegenerative disorder resulting from the death of dopamine neurons in the substantia nigra pars compacta. Dekker MC., Bonifati V., van Duijn CM. 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. Genetic research is one area that shows promise to push the science forward. Stanford IM., Cooper AJ. Given the reentrant nature of basal ganglia-thalamocortical connections, cortically initiated activation of the direct pathway should therefore result, in positive feedback at cortical levels, due to thalamic disinhibition.

National Library of Medicine Survival time, mortality, and cause of death in elderly patients with Parkinson's disease: a 9-year follow-up. Reduced dopaminergic activation of d2-like receptors on striatal-GPe neurons would increase the effectiveness of their glutamatergic inputs, leading to increase inhibition of GPe, which would in turn disinhibit STN. Unlike the fast-acting neurotransmitters glutamate and GABA, DA docs not itself cause depolarization or hyperpolarization of the postsynaptic membrane.228 As a slow-acting neurotransmitter, or neuromodulator, DA's synaptic effects unfold over hundreds of milliseconds and may last a minute or more. Benabid AL., Pollak P., Gross C., et al. Synaptic organisation of the basal ganglia. These include the following: (i) ubiquitin, the peptide with which damaged proteins are tagged in preparation for degradation by the 26S proteasome; (ii) fragments of the 26S proteasome; (iii) the E3 ubiquitin ligase parkin, which assists in preproteolytic ubiquination; and (iv) ubiquitin C-terminal hydroxylase L1 (UCH-L1), which removes ubiquitin for recycling following proteasomal degradation.111,148 This evidence for a role of proteolytic stress in the pathogenesis of sporadic PD is reinforced by the fact that mutations in the genes coding for a-synuclein, parkin, and UCH-L1 are associated with some forms of familial PD.111,167.
