When striatal projections are activated by the cortex, due to their neurochemical properties they tend to suppress the tonically active pallidal output that projects to thalamus (30).
Widespread destruction of the bilateral globus pallidus (both of internal and external segment) in monkeys resulted in severe forward bending and a so-called "flexed posture" (Richter, 1945 (33)), "somersault posture" (Carpenter et al., 1950 (6)), or "pallidal posture" (Denny-Brown, 1962 (4)).
Although hemichorea is most commonly caused by subthalamic nuclear lesions, the involvement of the striatopallidal pathway due to lesions affecting other basal ganglia regions results in the disinhibition of motor thalamic structures by reducing inhibitor signals to pallidal neurons, which leads to hemichorea (4).

Moreover, the lower right thalamic, pallidal and hippocampal ReHo were correlated with greater Allo task total errors in the NC group, which means NC with higher ReHo within these areas has better allocentric spatial navigation skills.
