The Dorsal Raphe Nucleus in the Control of Energy Balance
Trends in Neurosciences, 2021Energy balance is orchestrated by an extended network of highly interconnected nuclei across the central nervous system. While much is known about the hypothalamic circuits regulating energy homeostasis, the 'extra-hypothalamic' circuits involved are relatively poorly understood.

European Journal of Pharmacology, 2002 The interaction between the locus coeruleus and dorsal raphe nucleus was investigated by means of dual-probe microdialysis in conscious rats. The release of noradrenaline and 5-hydroxytryptamine (5-HT) after inhibition or stimulation of locus cocruleus ...

The Dorsal Raphe: An Important Nucleus in Pain Modulation
Brain Research Bulletin, 1994The dorsal raphe nucleus (DRN) is an important nucleus in pain modulation. It has abundant 5-HT neurons and many other neurotransmitter and/or neuromodulator containing neurons. Its vast fiber connections to other parts of the central nervous system provide a morphological basis for its pain modulating function.

Illuminating complexity in serotonin neurons of the dorsal raphe nucleus
Neuron, 2022The function of serotonin in the mammalian brain has been challenging to unravel. In this issue of Neuron, Paquelet et al. (2022) employ microendoscopy to record over 2,000 dorsal raphe serotonin neurons, yielding new insights into their activity from the single neuron to the population level.

Cytoarchitecture of the human dorsal raphe nucleus
Journal of Comparative Neurology, 1990AbstractSerial 50 μm Nissl‐stained sections through the midbrain and pontine central gray of four adult humans (mean age 56 years, mean postmortem delay 3 hours) were analysed and the subnuclei of the dorsal raphe nucleus (DR) delineated on the basis of neuronal morphology and density.

Chemoarchitecture of the primate dorsal raphe nucleus
Journal of Chemical Neuroanatomy, 1998The dorsal raphe nucleus (DR) harbours the largest single collection of serotonin (5-HT)-containing neurons in the brain but also comprises other types of chemospecific neurons. The aim of the present study was to characterise morphologically and immunohistochemically the DR in the squirrel monkey (Saimiri sciureus).

A Direct Retinal Projection to the Dorsal Raphe Nucleus in the Rat
Brain Research, 1994A direct projection from the retina to the dorsal raphe nucleus at the pontomesencephalic junction was demonstrated with both antero- and retrograde tracing techniques in the rat. Following intravitreous injections of choleratoxin subunit B (CTB), horseradish peroxidase (HRP) and CTB-conjugated HRP, varicose fibers were labeled in the lateral region of

Properties of IA in a neuron of the dorsal raphe nucleus
Brain Research, 2012Voltage clamp data were analyzed in order to characterize the properties of the fast potassium transient current I(A) for a presumed serotonergic neuron of the rat dorsal raphe nucleus (DRN). We obtain maximal conductance, time constants of activation and inactivation, and the steady state activation and inactivation functions m(∞) and h(∞), as ...

GABAergic modulation of serotonergic neurons in the dorsal raphe nucleus
Reviews in the Neurosciences, 2018Abstract The dorsal raphe nucleus (DRN), located in the brainstem, is involved in several functions such as sleep, temperature regulation, stress responses, and anxiety behaviors. This nucleus contains the largest population of serotonin expressing neurons in the brain.
