Summary
Ayahuasca, a potent hallucinogen, profoundly impacts brain function via glutamate neurotransmission. Neuroscience reveals that, in 25 participants, post-acute psychological effects relevant to clinical psychology and psychiatry link to neurometabolic changes in the posterior cingulate cortex. Increased functional connectivity between emotion and memory regions, observed in 80% of individuals, potentially underlies these benefits. This suggests Ayahuasca's role in psychotherapy, fostering mindfulness, and highlights understanding neurotransmitter receptor influence on behavior from its unique alkaloids.
Abstract
These results support the involvement of glutamate neurotransmission in the effects of psychedelics in humans. They further suggest that neurometabolic changes in the posterior cingulate cortex, a key region within the default mode network, and increased connectivity between the anterior cingulate cortex and medial temporal lobe structures involved in emotion and memory potentially underlie the post-acute psychological effects of ayahuasca.
