Lesion of posterior thalamus or vestibular nuclei
what happens with a lesion of the posterior thalamus
spatial inattention to postural alignment
hypothalamus fuction
integrates behaviors and visceral functions. maintains homeostasis
thyrotropin releasing hormone
increases secretion of thyroid
somatostatin
inhibits growth
