Neuroimaging of the periaqueductal gray: State of the field [PDF]

NeuroImage, 2012
This review and meta-analysis aims at summarizing and integrating the human neuroimaging studies that report periaqueductal gray (PAG) involvement; 250 original manuscripts on human neuroimaging of the PAG were identified. A narrative review and meta-analysis using activation likelihood estimates is included.

Functionally selective signaling for morphine and fentanyl antinociception and tolerance mediated by the rat periaqueductal gray. [PDF]

PLoS ONE, 2014
Functionally selective signaling appears to contribute to the variability in mechanisms that underlie tolerance to the antinociceptive effects of opioids.

Neural Correlates of Fear in the Periaqueductal Gray [PDF]

The Journal of Neuroscience, 2016
The dorsal and ventral periaqueductal gray (dPAG and vPAG, respectively) are embedded in distinct survival networks that coordinate, respectively, innate and conditioned fear-evoked freezing. However, the information encoded by the PAG during these survival behaviors is poorly understood.

Study on the central neural pathway and the relationship between the heart and small intestine via a dual neural tracer

PLoS ONE, 2022
Despite very different functions, studies increasingly report that there may be a potential central nervous anatomical connection between the heart and the small intestine.

The Midbrain Periaqueductal Gray Control of Respiration [PDF]

The Journal of Neuroscience, 2008
The midbrain periaqueductal gray (PAG) organizes basic survival behavior, which includes respiration. How the PAG controls respiration is not known. We studied the PAG control of respiration by injecting d , l -homocysteic acid in the PAG in ...

P/Q-type calcium-channel blockade in the periaqueductal gray facilitates trigeminal nociception: a functional genetic link for migraine? [PDF]

, 2002
The discovery of mis-sense mutations in the alpha1A subunit of the P/Q-type calcium channel in patients with familial hemiplegic migraine indicates the potential involvement of dysfunctional ion channels in migraine.

Exploration driven by a medial preoptic circuit facilitates fear extinction in mice

Communications Biology, 2023
A circuit running from CamKIIα-positive neurons of the medial preoptic area to the ventral periaqueductal gray induces exploration of a fear-conditioned place and facilitates fear extinction in mice.

Ventrolateral Periaqueductal Gray Neurons Are Active During Urination

Frontiers in Cellular Neuroscience, 2022
The ventrolateral periaqueductal gray (VLPAG) is thought to be the main PAG column for bladder control. PAG neurons (especially VLPAG neurons) and neurons in the pontine micturition center (PMC) innervating the bladder detrusor have anatomical and ...

Participation of pro-inflammatory cytokines in neuropathic pain evoked by chemotherapeutic oxaliplatin via central GABAergic pathway

Molecular Pain, 2018
Background Neuropathic pain is observed in patients as chemotherapeutic oxaliplatin is used to treat metastatic digestive tumors; however, the mechanisms responsible for hyperalgesia are not well understood.

Effects of Salmon Calcitonin on the Concentrations of Monoamines in Periaqueductal Gray in Formalin Test

Balkan Medical Journal, 2019
Background: The receptors of salmon calcitonin, located on certain areas of the brain such as the periaqueductal gray matter, are responsible for pain modulation.
