31. D1 dopamine receptor modulated MSNs send GABAergic inhibitory projections directly to the globus pallidus interna ( GPi ). 32. The inhibitory indirect pathway involved the inhibition of the globus pallidus internus allowing it to inhibit the thalamus. 33. The pulse generator will send an electric current to his brain, jamming nerve signals from the globus pallidus . 34. The subthalamic nucleus receives input mainly from the striatum and cerebral cortex, and projects to the globus pallidus . 35. And if lesions are burned into both sides of the globus pallidus , speech and cognition may be impaired. 36. From the core, the neurons project to other sub-cortical areas such as the globus pallidus and the substantia nigra. 37. The pars reticulata in conjunction with the Globus pallidus in the basal ganglia allows for inhibition of the thalamus. 38. The most commonly affected region of the brain is the lenticular nucleus and in particular the internal globus pallidus . 39. The globus pallidus and putamen are two nuclei of the basal ganglia which are both involved in motor skills. 40. Globus pallidus internus deep brain stimulation is the preferred surgical procedure due to the lower frequency of side effects.
