Caudal brainstem raphe nuclei: Neural substrate for their involvement in the expression of some biological rhythms
(1996-11-14)
Nucleus raphe pallidus (RPa) lies ventrally in the caudal brainstem, where it is coextensive rostrally with the nucleus raphe magnus (RMg) and caudally with the nucleus raphe obscurus (ROb). Retrograde neuronal tracing ...
5-HT neurons of the medullary raphe contribute to respiratory control in toads
(2021-11-01)
Air-breathing vertebrates undergo respiratory adjustments when faced with disturbances in the gas composition of the environment. In mammals, the medullary raphe nuclei are involved in the neuronal pathway that mediates ...
Patterns of fos activation in rat raphe nuclei during feeding behavior
(ELSEVIER SCIENCE BV, 2008)
To analyze the differential recruitment of the raphe nuclei during different phases of feeding behavior, rats were subjected to a food restriction schedule (food for 2 h/day, during 15 days). The animals were submitted to ...
Effect of electrolytic lesion of the median raphe nucleus on behavioral and physiological measures of stress.
(1999-12-01)
The effect of electrolytic lesion of the median raphe nucleus was measured on behavioral and physiological parameters related to stress 24 h after the lesion. In of the elevated plus-maze the lesion decreased the percentage ...

Opioid mu-receptors in the rostral medullary raphe modulate hypoxia-induced hyperpnea in unanesthetized rats
(Wiley-Blackwell, 2012-03-01)
Aim: It has been suggested that the medullary raphe (MR) plays a key role in the physiological responses to hypoxia. As opioid mu-receptors have been found in the MR, we studied the putative role of opioid mu-receptors in ...
