Glutamatergic projections from the rostral hypothalamus to the periaqueductal grey.
Retrograde transport of fluorescent latex microspheres was combined with immunocytochemistry for glutamate to determine the organization of the projections from glutamate-containing neurones in the rostral hypothalamus to the different subdivisions of the periaqueductal grey (PAG). Double-labelled neurones, i.e. neurones immunoreactive for glutamate and projecting to the PAG, were found throughout the rostral hypothalamus. There were no apparent differences, however, in the origins of presumed glutamatergic projections from the rostral hypothalamus to the different subdivisions of the PAG.
