The scans let us see just how the drug makes it suddenly seem like everything is so profound. In a separate study published in Cellscientists captured images of how LSD interacts with certain receptors in the brain. It turns out that LSD has a structural feature that makes it bind with the receptor for a long time and keeps the trip going for hours.
LSD has been around sincewhen it was synthesized by the chemist Albert Hofmann. But starting in the s, LSD along with mushrooms and MDMA was deated a tightly controlled substance as part of the war on drugs. As a result, there has been very little research on any of these substances. Another psychedelic drug, psilocybin, is being studied to help ease fears of death in cancer patients. Given this new interest, having a better grasp of the structure of LSD can help us develop better drugs for a variety of conditions.
And knowing how the brain creates meaning can be useful for understanding the neurological basis of mental illnesses like schizophrenia. More recent research has suggested both psilocybin and LSD may help with cluster headachessometimes called suicide headaches because they are so severe that people who experience them often kill themselves. The volunteers were divided into three groups: people who took micrograms of LSD a typical dose for people who want to trippeople who took a placebo, and people who took the LSD along with an acid-canceling drug called ketanserin. More on the this last group later.
After that, they rated how meaningful the snippets were. There were two interesting findings. The people who took LSD found the jazz more meaningful than the people in either of the other groups. The people who had a proper trip suddenly seemed to appreciate the new music more. This makes sense for the people who took LSD versus a placebo. But what about the third group of people who took LSD and ketanserin? Ketanserin is a drug that blocks the ability of LSD to interact with a chemical called serotonin.
So, we know that ketanserin blocks serotonin, and that taking ketanserin blocked the effects of acid. This proves that many effects of LSD are caused by how the drug interacts with serotonin, according to Adam Halberstadta professor of psychiatry at the University of California at San Diego who was not involved in the study.
Earlier animal studies suggested that a different brain receptor, one that affects dopamine, might be responsible for LSD effects. In this case, the active area was a set of structures called the cortical midline structures.
This makes sense, because we already knew that this area plays a role in creating identity and a sense of self. Next, Preller wants to study whether we can get the same effect when people are experiencing meaningful images or touch instead of sound. So we know how LSD creates meaning.
But why do the trips last so long? They took images of how the LSD binds to various serotonin receptors — including the receptor in the Preller study. For many other compounds like serotonin, the lid remains rather flexible.
