Lateral habenula glutamatergic neurons projecting to the dorsal raphe nucleus promote aggressive arousal in mice

Nature Communications, 2022
The dorsal raphe nucleus (DRN) is known to modulate aggressive behaviour in rodents. Here the authors show that glutamatergic projections from the lateral habenula to DRN modulate aggression between male mice.

Electro-oscillographic correlation between dorsal raphe nucleus, neocortex and hippocampus during wakefulness before and after serotoninergic inactivation

Brazilian Journal of Medical and Biological Research, 1999
Theta rhythm in many brain structures characterizes wakefulness and desynchronized sleep in most subprimate mammalian brains. In close relation to behaviors, theta frequency and voltage undergo a fine modulation which may involve mobilization of dorsal ...

PROJECTIONS OF DORSAL AND MEDIAN RAPHE NUCLEI TO DORSAL AND VENTRAL STRIATUM [PDF]

Acta Medica Iranica, 2007
The ascending serotonergic projections are derived mainly from mesencephalic raphe nuclei. Topographical projections from mesencephalic raphe nuclei to the striatum were examined in the rat by the retrograde transport technique of HRP (horseradish ...

Dorsal raphe nucleus controls motivation-state transitions in monkeys. [PDF]

Sci Adv
The dorsal raphe nucleus (DRN) is an important source of serotonin in the brain, but fundamental aspects of its function remain elusive. Here, we present a combination of minimally invasive recording and disruption studies to show that DRN brings about ...

Dorsal Raphe Nucleus Down-Regulates Medial Prefrontal Cortex during Experience of Flow [PDF]

Frontiers in Behavioral Neuroscience, 2016
Previous neuroimaging studies have suggested that the experience of flow aligns with a relative increase in activation of the dorsal raphe nucleus, and relative activation decreases of the medial prefrontal cortex and of the amygdala.

Photostimulation Alters c-Fos Expression In The Dorsal Raphe Nucleus [PDF]

Brain Research, 2005
Retinal afferents to the dorsal raphe nucleus (DRN) have been described in a number of species, including Mongolian gerbils, but functional correlates of this optic pathway are unknown at present.

Glutamatergic drive of the dorsal raphe nucleus [PDF]

Journal of Chemical Neuroanatomy, 2011
The dorsal raphe nucleus (DR) contains the majority of serotonin (5-hydroxytryptamine, 5-HT) neurons in the brain that regulate neural activity in forebrain regions through their widespread projections. DR function is linked to stress and emotional processing, and is implicated in the pathophysiology of affective disorders.

Dorsal raphe nucleus enkephalin peptide modulates behavioral preference. [PDF]

Neuropsychopharmacology
Abstract The endogenous opioid system is a powerful modulator of motivation and affect. The dorsal raphe nucleus (DRN) in the midbrain has been established as an important site of opioid action and is an integral hub in behavioral modulation.

Anatomic and Functional Topography of the Dorsal Raphe Nucleus [PDF]

Annals of the New York Academy of Sciences, 2004
Abstract: Serotonergic systems play an important and generalized role in regulation of sleep‐wake states and behavioral arousal. Recent in vivo electrophysiologic recording studies in animals suggest that several different subtypes of serotonergic neurons with unique behavioral correlates exist within the brainstem raphe nuclei, raising the ...
