  4. HYPOTHALAMUS

  5. Hypothalamus Inputs: -amygdala (via stria terminalis & direct) -hippocampus (via fornix) -septal nuclei (via medial forebrain bundle) -brainstem & spinal cord (via medial forebrain bundle)

  6. Hypothalamus Outputs: -amygdala (via stria terminalis) -hippocampus (via fornix) -septal nuclei (via medial forebrain bundle) -brainstem & spinal cord sympathetic and parasympathetic preganglionic neurons -pituitary (neural & humoral) -anterior thalamus (to prefrontal, orbital, & cingulate cortex)
