the lateral bed nucleus also contained cholecystokinin-octapeptide , substance p , neurotensin and methionine-enkephalin immunoreactivity which probably derived from the central amygdaloid nucleus , whilst cholecystokinin-octapeptide , and especially substance p-containing fibres , were found in the medial bed nucleus and probably arise from cells in the medial amygdala .
