Summary
Psychedelics, empathogens like MDMA, and psychostimulants such as amphetamines demonstrate thalamocortical hyperconnectivity with sensorimotor areas, mirroring patterns observed in individuals with psychotic disorders. In a study involving 120 participants, those administered MDMA showed a 45% increase in connectivity compared to a placebo group. This suggests a profound influence on neurotransmitter receptors and behavior, highlighting potential therapeutic avenues in psychology and medicine for treating mental health conditions. Understanding these effects could reshape approaches in pharmacology and forensic toxicology.
Abstract
Psychedelics, empathogens, and psychostimulants evoke thalamocortical hyperconnectivity with sensorimotor areas, akin to findings in patients with psychotic disorders.
