It has been suggested that cerebellar connections between the
subthalamic nucleus and cerebellum via the pontine nuclei (PN) may account for the resting tremors in patients with PD (36).
The globus pallidus,
subthalamic nuclei, and pars reticulata of the substantia nigra are normally rich in iron.
The most common associations are lesions of the contralateral
subthalamic nuclei or its connections, due to vascular lesions, tumours, HIV infection, toxins or a metabolic disturbance.
The electrodes were implanted in the
subthalamic nucleus in eight patients, in the globus pallidus internus in three, and in the ventral intermediate nucleus in one.
The research has revealed why a subset of neurons in part of the brain called the
subthalamic nucleus is a potential target for pain relief in PD, as well as other diseases such as dementia, motor neuron disease and Huntington's, and certain forms of a migraine.
Soon, the thalamus was removed from the definition, but the
subthalamic nucleus in the diencephalon and the substantia nigra in the midbrain were included, because these two nuclei have close associations with the globus pallidus.
Movement disorders following lesions of the thalamus or
subthalamic region.
Bilateral
subthalamic nucleus stimulation for the treatment of Parkinson's disease: results of six patients.
Moreover, some studies revealed that emotion recognition abnormalities may occur after
subthalamic nucleus stimulation [182-185], probably due to alterations of projections to cortical areas, particularly the OFC, which has been already implicated in emotion recognition [186].
