The rostral ventrolateral medulla (RVLM), also known as the pressor area of the medulla, is a brain region that is responsible for basal and reflex control of sympathetic activity associated with cardiovascular function. (wikipedia.org)
Specifically, we focus on changes in the rostral ventrolateral medulla (RVLM), a critical brain region for basal and reflex control of sympathetic activity. (wikipedia.org)
The rise in blood pressure during an acute aversive stress has been suggested to involve activation of angiotensin type 1A receptors (AT(1A)Rs) at various sites within the brain, including the rostral ventrolateral medulla. (edu.au)
In this study we examine the involvement of AT(1A)Rs associated with a subclass of sympathetic premotor neurons of the rostral ventrolateral medulla, the C1 neurons. (edu.au)
The overall distribution correlated with that of the AT(1A)Rs mapped by other methods and demonstrated that the majority of C1 neurons express the AT(1A)R. Cre-recombinase expression in C1 neurons of AT(1A)R-floxed mice enabled demonstration that the pressor response to microinjection of angiotensin II into the rostral ventrolateral medulla is dependent upon expression of the AT(1A)R in these neurons.

Consistent findings on MR imaging indicative of CM are attenuation/obliteration of the dorsal subarachnoid space at the cervicomedullary junction and rostral displacement of the caudal cerebellum by the occipital bone. (vin.com)
Nucleus solitarius divides into two parts: rostral and caudal. (statpearls.com)
The carotid body detects changes in PaCO2 through chemoreceptors, and this information gets conveyed to the nucleus solitarius (NTS) glutamatergic neurons that will target rostral ventrolateral medulla and respiratory pattern generator, leading to increased sympathetic activity. (statpearls.com)
Interneuronal α-synuclein transfer, which underlies protein spreading from the medulla oblongata to more rostral brain regions in this rat model, is not a mere consequence of passive release from damaged or dead neurons. (biomedcentral.com)
Therefore, the authors asked whether activation of mu receptors in the caudal, medial, or rostral MRR depressed ventilation and the response to hypercapnia, respectively. (silverchair.com)
These results lead to the conclusion that mu receptors in the caudal MRR rather than the middle MRR or rostral MRR are important but not exclusive for attenuating the hypercapnic ventilatory response. (silverchair.com)
