Previous studies have shown that the probability of ASR increases in patients with idiopathic RLS, which was attributed to disinhibition of reticulospinal pathways secondary to dopamine deficiency (30).
It is centered on a pair of reticulospinal neurons called the Mauthner neurons (M-cells), whose activation is necessary to mediate the C-start escape response that propels the animal away from threats by rapid flexion of the body (Fig.
Our results also can be attributed to the fact that after stroke, muscles acting against gravity have an increased myelination in the contralesional reticulospinal tract [26,27] and the results indicated that reticulospinal system has the capacity to support bilateral coordination of limb movements using reciprocal actions within a limb or on both sides [28].
The reduction from corticospinal control signals results in an increased dependence on residual brainstem descending pathways (such as vestibulospinal, reticulospinal, and rectospinal pathways) [22], which may activate extensive branching and innervate more neurons over spinal segments.
Two balanced descending systems are controlling stretch reflex activity: the inhibitory dorsal reticulospinal tract and facilitatory medial reticulospinal tract and vestibulospinal tract.
In parkinsonism, globus pallidus interna hyperactivity results in more inhibitory GABAergic input to the PPN, leading to reduced activity of the glutamatergic PPN neurons, which project to the reticulospinal neurons of brainstem and spinal cord, causing abnormal changes in locomotion and muscle tone.[sup][21] MSA has more rapid and widespread pathology than PD.

Among the reticulospinal neurons of the lamprey brain, there are 36 identifiable giant descending neurons [23], whose axons project almost the entire length of the SC.
