In a recent study, neuroscientists at the University of Cambridge investigated the brain activity of 12 sheep that were administered ketamine. 

The study aimed to understand the effect of drugs on the brains of people with Huntington’s disease.  

Huntington’s disease is a genetic condition that stops parts of the brain from working over time.  

According to the recent study high doses of ketamine can temporarily switch off the brain.  

Researchers measured changes in the animal’s brain waves once ketamine was administered. Ketamine is an anaesthetic and pain relief drug which is used by over 100,000 people in the UK.

Six sheep were given a 24mg/kg dose of ketamine and within two minutes the brain activity of five of the six stopped completely, one for several minutes. 

This has never been seen before in academic research.  

The study into Huntington’s disease is using sheep under the influence of ketamine showed that the brain can switch on and off in a matter of minutes.  

The researchers think that this pause in brain activity may correspond to what ketamine users describe as the K-hole.
