Direct Pathway Of Movement - Overview of Neuronal Connections and Normal Function
... The direct pathway passes through the caudate, putamen, and globus pallidus, which are parts of the basal ganglia ... In a resting individual, a specific region of the globus pallidus, known as the internus, and a portion of the substantia nigra, known as the pars reticulata, send ... inhibitory and, once they become activated, send inhibitory signals to the globus pallidus internus and substantia nigra pars reticulata ...
Medium Spiny Neuron - Direct Pathway Within The Basal Ganglia
... the medium spiny neurons project to the internal division of the globus pallidus which in turn sends axons to the substantia nigra pars reticulata (SNpr) and the ventroanterior and ventrolateral thalamus (VTh) ... Neurons in the globus pallidus are also inhibitory, thus inhibiting the excitatory neurons in the SNpr and VTh ... But in contrast to the medium spiny neurons, globus pallidus neurons are tonically active when not activated ...
Spasmodic Torticollis - Treatment - Deep Brain Stimulation
... These patients are subjected to stimulation of the globus pallidus internus, or the subthalamic nucleus ... To stimulate the globus pallidus internus, microelectrodes are placed into the globus pallidus internus bilaterally ... The stimulation of the globus pallidus internus disrupts the abnormal discharge pattern in the globus pallidus internus, resulting in inhibition of hyperactive cortical ...
Lateral Globus Pallidus
... The lateral globus pallidus (or external, GPe) receives a strong glutamatergic projection from the subthalamic nucleus ... The axons of the external globus pallidum go essentially to the subthalamic nucleus ... striatum, the substantia nigra pars reticulata, and the internal globus pallidus, where they release the neurotransmitter GABA ...
Medium Spiny Neuron - Indirect Pathway
... In this pathway the medium spiny neurons in the striatum project to the external segment of the globus pallidus ... These neurons in turn project to the internal segment of the globus pallidus and to the subthalamic nuclei which form a closed loop by projecting back to the internal globus pallidus ... excitement of medium spiny neurons causes them to inhibit external globus pallidus neurons ...
