3. Afferent Inputs to the Hypothalamus. In order to maintainhomeostasis the hypothalamus must receive inputs about the state of thebody. The major inputs include:a. Nucleus of Solitary Tract- this nucleus collects all of the visceralsensory information from the vagusb. Limbic System via the fornix- structures such as the amygdala andolfactory cortex (piriform lobe) project to the hypothalamus and helpregulate behaviors such as eating and reproduction.c. Retina via direct branches of the optic nerve that go to thesuprachiasmic nucleusd.
