This volume provides a comprehensive understanding of the human hypothalamus, an extremely complex structure that consists of a large number of very different functional units. It approaches the subject in a way that has not historically existed in standard neuropathological investigations of the human brain. As the hypothalamus was traditionally considered to be a neuroendocrine structure, and hence of little interest to neurologists, this volume explores new findings in the field and the value they bring to the field of neurology. New understandings of the role the hypothalamus plays in memory and attention deficits in the dementias, along with greater evidence that the hypothalamus is related to symptoms and signs in both neurological and psychological disorders provide users in the fields of neuroscience, endocrinology, pediatrics, and psychology with a comprehensive resource on which to base new research and exploration.
