Purinergic transmission in the rostral but not caudal medullary raphe contributes to the hypercapnia-induced ventilatory response in unanesthetized rats
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
The medullary raphe (MR) is a putative central chemoreceptor site, contributing to hypercapnic respiratory responses elicited by changes in brain PCO2/pH. Purinergic mechanisms in the central nervous system appear to ...
Serotonergic neurons in the nucleus raphé obscurus are not involved in the ventilatory and thermoregulatory responses to hypoxia in adult rats
(2013-06-15)
The medullary raphé is an important component of the central respiratory network, playing a key role in CO2 central chemoreception. However, its participation in hypoxic ventilatory responses is less understood. In the ...

Impact of ovariectomy and CO2 inhalation on microglia morphology in select brainstem and hypothalamic areas regulating breathing in female rats
(2021-04-01)
The neural network that regulates breathing shows a significant sexual dimorphism. Ovarian hormones contribute to this distinction as, in rats, ovariectomy reduces the ventilatory response to CO2. Microglia are neuroimmune ...
High CO(2)/H(+) dialysis in the caudal ventrolateral medulla (Loeschcke`s area) increases ventilation in wakefulness
(ELSEVIER SCIENCE BV, 2010)
Central chemoreception, the detection of CO(2)/H(+) within the brain and the resultant effect on ventilation, was initially localized at two areas on the ventrolateral medulla, one rostral (rVLM-Mitchell`s) the other caudal ...
ANATOMICAL AND FUNCTIONAL CONNECTIONS BETWEEN THE LOCUS COERULEUS AND THE NUCLEUS TRACTUS SOLITARIUS IN NEONATAL RATS
(Elsevier B.V., 2016-06-02)
This study was designed to investigate brain connections among chemosensitive areas in newborn rats. Rhodamine beads were injected unilaterally into the locus coeruleus (LC) or into the caudal part of the nucleus tractus ...
Contribución de los astrocitos troncoencefálicos en la quimiorrecepción central respiratoriaContribution of brainstem astrocytes in central respiratory chemoreception
(2018)
La quimiorrecepción central respiratoria es esencial para ajustar la respiración frente a las demandas fisiológicas, y para mantener la homeostasis de PCO2 y pH en el cerebro. Se ha descrito que los astrocitos de la ...
