Have you ever heard of a treatment that emerged from the past? Well, there are many to consider, but a street drug made its exposure over 60 years ago.
People believed this could help treat depression. Introducing Lysergic acid diethylamide (LSD), commonly called acid, changes how people sense the world surrounding them. It comes as a white powder or clear colorless liquid. However, Neuroscience studies show that LSD “frees brain activity from anatomical restrictions.” Truth being provided, some effects are unpredictable depending upon the amount taken. We do not worry about how LSD is legal and is not considered an addictive drug. Still, users who have developed tolerance to it must have consumed progressively larger doses than usual.
According to NeuroImage, new research has shown that LSD’s psychedelic effects may cause functional connectivity and brain structure to be less intense. This study also indicates that LSD can increase the complexity of a segregated brain state. These findings offer new insight into the relationship between consciousness and brain function.
Studies of consciousness usually focus on the loss of consciousness, such as sleep, anesthesia, or coma. We believe it is possible to gain insights by studying altered states of consciousness, such as LSD-induced psychedelic states.
Considering consciousness is the integration of multiple brain networks and subnetworks. Researchers sought to understand how these patterns of brain connectivity changed over time with the help of LSD.
Luppi and his associates used functional magnetic resonance imaging to study the brain connectivity and structural structure of 15 healthy volunteers in two different sessions. Participants were administered a placebo during one session. They were then given active LSD doses during the second session.
“Neurons that fire together, wire together” is the norm. However, the researchers discovered that LSD caused brain activity to be “less constrained than normal by the presence or lack of an underlying anatomy connection.”
“We know that brain structure can have a significant influence on the brain function in normal circumstances. Using LSD, the relationship is weaker compared to the former. The system makes function less constrained.” Luppi explained that this is almost the exact opposite of anesthesia.
According to the study’s authors, LSD influenced the brain in a way that allowed it to explore functional connectivity patterns beyond the ones imposed by anatomy. It could have led to the unusual beliefs and experiences that the researchers reported during the psychedelic experience. It also reflected an increase in functional complexity.
Luppi explained to PsyPost, “Integration of information and segregation are fundamental properties of brain functioning: We found LSD does not affect them equally but has specific effects on each.” These brain integration or segregation changes also fluctuated over time and were associated with subjective experiences.
One example is losing your sense of self in a psychedelic experience. This phenomenon, also known as “ego death” or “ego dissolution,” was linked to a high level of global integration.
Luppi stated that this is a relatively new area in neuroscience and that more research will be required to understand the effects of LSD and other psychoactive drugs on brain function. A better understanding of the effects of LSD and other psychedelics on brain function may help to identify potential clinical applications, such as ongoing research at the Centre for Psychedelic Research (London).
He said that studying psychoactive substances provides a unique opportunity in neuroscience. We can explore their effects on brain chemistry, brain function level, and subjective experiences. “In particular, the mind and brain are never static. We are discovering that the journey is just as important as the destination regarding brain function, its evolution over time, and brain function.”
