Tail Flick Modification of Orexin-A Induced Changes of Electrophysiological Parameters in The Rostral Ventromedial Medulla [PDF]

open access: yesCell Journal, 2014
Objective: It is well known that intracerebroventricular (ICV) and supraspinal injections of orexin-A elicit analgesia, but the mechanism(s) of action remains unidentified.

The periaqueductal gray and Bayesian integration in placebo analgesia

open access: yeseLife, 2018
In placebo hypoalgesia research, the strength of treatment expectations and experiences are key components. However, the reliability or precision of expectations had been mostly ignored although being a likely source for interindividual differences.

An Anterior Cingulate Cortex‐Anterior Insular Cortex Glutamatergic Circuit Gates Stress‐Induced Visceral Hypersensitivity and Anxiety via Ionotropic Glutamate Receptors Trafficking

open access: yesAdvanced Science, Volume 13, Issue 52, 18 September 2026.
This study identifies an anterior cingulate cortex (ACC) to anterior insular cortex (AIC) glutamatergic (Glu) circuit that gates stress induced visceral hypersensitivity and anxiety. Circuit activation induces both phenotypes, whereas inhibition relieves them.

Hyperalgesia during acute opioid abstinence: evidence for a nociceptive facilitating function of the rostral ventromedial medulla

open access: yes, 1991
Naloxone-precipitated opioid abstinence is associated with enhancement of reflex responses to noxious stimulation (hyperalgesia). The present experiments in lightly anesthetized rats were designed to determine (1) whether neurons in the rostral ...

The Neuroscience of Religious and Spiritual Practices: A Systematic Review of Neurotheological Evidence

open access: yesBrain and Behavior, Volume 16, Issue 9, September 2026.
Systematic synthesis of 105 neuroimaging and neurophysiological studies demonstrates that religious and spiritual practices, including meditation, prayer, chanting, worship, and mystical experiences, produce practice‐specific neuroplastic changes in brain networks governing attention, self‐referential processing, emotion regulation, connectivity ...

Depressor neurons in rabbit caudal medulla act via GABA receptors in rostral medulla

open access: yes, 1988
Experiments were conducted in urethan-anesthetized rabbits to determine whether vasomotor effects elicited by activation or inhibition of the caudal ventrolateral medulla depend on gamma-aminobutyric acid (GABA)ergic, glycinergic, or alpha-adrenergic ...

Differential modulation of neurons in the rostral ventromedial medulla by neurokinin-1 receptors

open access: yesJournal of Neurophysiology, 2012
The rostral ventromedial medulla (RVM) is part of descending circuitry that modulates nociceptive processing at the level of the spinal cord. RVM output can facilitate pain transmission under certain conditions such as inflammation, and thereby contribute to hyperalgesia.
