RESUMO
Neuropeptide Y (NPY) experimentally administered to the surface of the optic tectum in visually stimulated fire bellied toads diminishes local glucose utilization in the retinorecipient tectal laminae. Strong NPY-induced suppression of tectal glucose utilization was found even when visual retinal input to the tectum was boosted pharmacologically under systemic apomorphine treatment. These novel results on the local cerebral energy metabolism contribute to the concept that NPY controls retinotectal visual processing via an inhibitory mechanism.
