Further evidence for a complex system controlling feeding behavior

摘要: Abstract The distribution of brain regions involved in feeding behavior was explored by disturbing synaptic conduction and interrupting neural pathways. Food consumption hungry rats significantly reduced blocking (with procaine hydrochloride) the lateral hypothalamus, anterolateral globus pallidus but not similar disturbances amygdala, preoptic area, posterolateral or caudate nucleus. A second experiment interrupted pathways with cuts order to examine organization circuitry region hypothalamus. severe aphagia adipsia followed coronal plane anterior posterior Less effects occurred sagittal hypothalamus through internal capsule. There only a transient effect area. These results suggest circuit which passes from brainstem longitudinally where separate bundles pass thalamus.
