Answer to Question 1

Answer: For reaching behavior, the parietal reach region located in the medial posterior parietal cortex is active when individuals are about to make a pointing or reaching movement. In contrast, the anterior part of the intraparietal sulcus is involved in controlling hand and finger movements necessary to grasp an object.

Answer to Question 2

Answer: Huntington's disease (HD) is caused by degeneration of the caudate nucleus and the putamen (and loss of GABA function). The disease is marked by uncontrollable jerky movements of the arms and legs. Parkinson's disease is associated with neurodegeneration of the nigrostriatal dopamine system and involves tremor at rest, muscle rigidity, slowness of movement, and postural instability.
