Answer to Question 1

Visuospatial processing occurs in the right hemisphere and motor control is contralateral, so the patient is able to accurately draw a cube with the contralateral (left) hand but not the ipsilateral hand.

Answer to Question 2

The hypothalamus is involved in regulating the endocrine system; the activities of the autonomic nervous system; survival behavior (e.g., fighting, feeding, fleeing, and mating); consciousness; and emotions, pleasure, pain, and stress reactions.
