The central nervous system plays a pivotal role in the regulation of energy
homeostasis. Within the brain, there is a structure called hypothalamus and this
structure is divided into multiple subregions (also called nuclei, note this is not the
same as the nucleus within a cell) that are involved in controlling feeding behavior
and energy homeostasis. Please read the relevant pages in our text and the article by
Timper and Bruining Hypothalamic circuits regulating appetite and energy
homeostasis_ pathways to obesity_ Timper and Bruning1 and answer the following
