Ketamine what is a k hole

They also took EEG readings of their cerebral cortices to see how the brain's electrical activity matches up with their drug experiences. At the lower doses, they found that the brain goes through three phases while on ketamine. They lost the ability to move, but their eyes stayed open they could also blink.

You can think of that as a conversation in a busy restaurant. Things seem chaotic while lots of information is being exchanged during conversations at different tables. During the second phase of a ketamine high, the team observed oscillations between lower frequency theta waves and higher frequency gamma waves. There's a lot of talking, but not a lot of information being exchanged.

The brain is processing reality and exchanging information, in a uniform but very different way. In turn, the six sheep who received the highest doses of ketamine had very different patterns of brain activity shortly after getting dosed.

In five of the sheep, after two minutes, their brain activity seemed to shut off. Sheep brains and human brains are far from perfect parallels, and the team was only imaging the cerebral cortex.

In the last 18 months telemedicine has been used for much more than simple check-ins with the primary care physician, it's now being used to help with…. An expert breaks down the many factors that contributed to the current overdose crisis and what it will take to break the trend. Harm reduction is more than a "common sense" approach. It's a movement designed to protect the health, safety, and agency of people who use drugs. Caffeine is found in many migraine drugs, but too much caffeine can also be a trigger.
