Longitudinal animal experiments in the field of regenerative biology often require repeated use of short-term anesthesia (minutes to a few hours). Regain of consciousness limits the level of ...

I set out to trace how a once-fringe idea, that consciousness might depend on quantum activity in the brain’s microscopic scaffolding, has converged with new anesthesia research and a bold proposal ...

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, ...

(Katlowitz et al., Nature, 2026, color adjusted) Our brains might be more alert when unconscious than we realized. A new study of brain cells in the hippocampus shows that people under general anesthe ...

A major finding by a doctor at the Harvard Medical School may revolutionize the administration of anesthetics to patients awaiting surgery. If current applications of the new discovery prove ...

Rabbits are one of the most used experimental animals in biology and medical research because they are docile, easy to raise, moderate in size and omnivorous. For disease modeling in rabbits, various ...

An innovative study uses the anesthetics propofol and isoflurane in humans to study the patterns of reemerging consciousness and cognitive function after anesthesia. Millions of surgical procedures ...

Records provided to FOX Investigators by Rise for Animals show the University of Wisconsin School of Veterinary Medicine performed experiments on six beagles from Ridglan Farms in 2023 that ended with ...
