Summary of "Dynamics of Ketamine-induced Loss and Return of Consciousness across Primate Neocortex."

Ketamine is a noncompetitive N-methyl-D-aspartate antagonist and is known for unique electrophysiologic profiles in electroencephalography. However, the mechanisms of ketamine-induced unconsciousness are not clearly understood. The authors have investigated neuronal dynamics of ketamine-induced loss and return of consciousness and how multisensory processing is modified in the primate neocortex.

Dynamics of recovery from anaesthesia-induced unconsciousness across primate neocortex.

How the brain recovers from general anaesthesia is poorly understood. Neurocognitive problems during anaesthesia recovery are associated with an increase in morbidity and mortality in patients. We stu...

Nonlinear dynamics captures brain states at different levels of consciousness in patients anesthetized with propofol.

The information processing capability of the brain decreases during unconscious states. Capturing this decrease during anesthesia-induced unconsciousness has been attempted using standard spectral ana...

Exogenous GM1 Ganglioside Attenuates Ketamine-Induced Neurocognitive Impairment in the Developing Rat Brain.

A prolonged exposure to ketamine triggers significant neurodegeneration and long-term neurocognitive deficits in the developing brain. Monosialotetrahexosylganglioside (GM1) can limit the neuronal dam...

(R)-ketamine induces a greater increase in prefrontal 5-HT release than (S)-ketamine and ketamine metabolites via an AMPA receptor-independent mechanism.

Although recent studies provide insight into the molecular mechanisms of the effects of ketamine, the antidepressant mechanism of ketamine enantiomers and their metabolites are not fully understood. I...

Peripheral antinociception induced by ketamine is mediated by the endogenous opioid system.

Ketamine is a drug largely used in clinical practice as an anesthetic and it can also be used as an analgesic to manage chronic pain symptoms. Despite its interactions with several other signaling sys...

Clinical Trials [8046 Associated Clinical Trials listed on BioPortfolio]

Ketamine Plus Lithium in Treatment-Resistant Depression

The purpose of this study is to test the antidepressant effect of ketamine when given repeatedly over a period of 1 week, as well as the use of Lithium as a relapse-prevention strategy for...

Effects of TAK-063 on Preventing Ketamine-Induced Brain Activity Changes as Well as Psychotic-Like Symptoms in Healthy Male Adults

The purpose of this study is to determine whether ketamine-induced brain activity changes are modulated by TAK-063 administration using neuroimaging battery tests.

Influence of Intracranial Lesions on Bispectral Index

The purpose of this study is to assess whether BIS values at return of consciousness are different in patients with or without brain tumors.

Reducing Ketamine-Induced Agitation, by Midazolam or Haloperidol Premedication After Adult Procedural Sedation

Ketamine is the cornerstone of procedural sedation in emergency department but ketamine induced agitation has limited its usage by many physicians. As a solution, some propose using midazo...

Ketamine Associated With Morphine PCA After Total Hip Arthroplasty

Ketamine (an analgesic drug often associated with morphine in the treatment of Opioid Induced Hyperalgesia) is often mixed in Morphine PCA syringe. We make the hypothesis that ketamine adm...

Medical and Biotech [MESH] Definitions

A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.

A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.

The use of several ANESTHETICS together in small amounts, as opposed to a larger amount of one drug, to induce loss of sensation and loss of consciousness.

The period of emergence from general anesthesia, where different elements of consciousness return at different rates.

Compounds capable of relieving pain without the loss of CONSCIOUSNESS.
