This study, besides to delineate the cytoarchitecture and the localization in the brainstem of the human raphé nuclei, aims to evaluate the correlation between neuropathological raphé defects ...

Molecular Psychiatry - Glucocorticoid modulation of tryptophan hydroxylase-2 protein in raphe nuclei and 5-hydroxytryptophan concentrations in frontal cortex of C57/Bl6 mice.

In order to settle this debate, the Caltech team focused on a region called the raphe nuclei, which has the brain's main population of serotonin-producing (or serotonergic) neurons.

The bacteria may speed up learning because the Raphe nuclei stimulate a brain region called the hippocampus, which handles spatial memory, she says.

As if low energy weren't depressing enough, the lack of light may also cause neurons called raphe nuclei to cut back production of serotonin, the feel-good neurotransmitter.
