5-HT1A receptors in the dorsal hippocampus mediate the anxiogenic effect induced by the stimulation of 5-HT neurons in the median raphe nucleus
(Elsevier B.V., 2008-04-01)
We evaluated the involvement of dorsal hippocampus (DH) 5-HT1A receptors in the mediation of the behavioral effects caused by the pharmacological manipulation of 5-HT neurons in the median raphe nucleus (MRN). To this end, ...
The dorsal raphe nucleus exerts opposed control on generalized anxiety and panic-related defensive responses in rats
(Elsevier B.V., 2003-06-16)
It has been proposed that the ascending dorsal raphe (DR)-serotonergic (5-HT) pathway facilitates conditioned avoidance responses to potential or distal threat, while the DR-periventricular 5-HT pathway inhibits unconditioned ...
Whole body sodium depletion modifies AT1 mRNA expression and serotonin content in the dorsal raphe nucleus
(2019-04-01)
Angiotensin II (Ang II) acts on Ang II type 1 (AT1) receptors located in the organum vasculosum and subfornical organ (SFO) of the lamina terminalis as a main facilitatory mechanism of sodium appetite. The brain serotonin ...
The lateral habenula regulates defensive behaviors through changes in 5-HT-mediated neurotransmission in the dorsal periaqueductal gray matter
(ELSEVIER IRELAND LTD, 2010)
Chemical stimulation of the lateral nucleus of the habenula (LHb), an area implicated in the regulation of serotonergic activity in raphe nuclei, affects the acquisition of inhibitory avoidance and escape expression of ...
Anxiolytic-like effects of median raphe nucleus lesion in the elevated T-maze
(Elsevier B.V., 2004-08-12)
The cell bodies of 5-HT containing neurons that innervate the limbic forebrain are mainly found in the dorsal raphe nucleus and in the median raphe nucleus (MRN). To assess the role of the median raphe nucleus in anxiety, ...

Role of 5-HT in stress, anxiety, and depression
(Elsevier B.V., 1996-05-01)
There are conflicting results on the function of 5-HT in anxiety and depression. To reconcile this evidence, Deakin and Graeff have suggested that the ascending 5-HT pathway that originates in the dorsal raphe nucleus (DRN) ...
