The posterior hypothalamic nucleus has been implicated as an area controlling autonomic activity. afferent input to the will provide evidence its role in function. In present study, we aimed identify detailed anatomical projections from cortical, subcortical and brainstem structures, using horseradish peroxidase (HRP) retrograde axonal transport technique rat. Subsequent injection of HRP into nucleus, extensive cell labelling was observed bilaterally various areas cerebral cortex including cingulate, frontal, parietal insular cortices. At levels, labelled cells were medial lateral septal nuclei, bed stria terminalis, thalamic amygdaloid nuclei. Also axons vertical horizontal limbs diagonal band localised at CA1 CA3 fields hippocampus dentate gyrus. medial, parasolitary intercalated medulla, sensory nuclei trigeminal nerve, reticular, vestibular, raphe central grey also received cerebellar upper cervical spinal levels. results are discussed relation involvement function allows a better understanding how brain controls visceral
