What exactly happens in a brain when it is hit by a hallucinogen?

Now, a team of Swiss researchers has used MRI imaging to follow the brain as it's under the influence of acid.

And their results support the idea that hallucinogens cause the breakdown of the system that helps the brain keep track of which information is coming from the real world and which is generated by the brain itself.

Your brain has to essentially decide which of it to take seriously and raise to the level of consciousness, which to monitor subconsciously, and which to discard.

Based on this and additional research, neuroscientists have proposed that the thalamus acts as a gatekeeper for sensory information flowing into the cortex.

As a consequence, the cortex gets overwhelmed by information and starts losing track of information, leading to a flood of intense sensations and other cognitive disruptions.
