Effects of Serotonergic Psychedelics on Synaptic Function and Neuroplasticity

OPUS FAU - Online publication system of Friedrich-Alexander-Universität Erlangen-Nürnberg  – January 01, 2026

Summary

Serotonergic psychedelics like LSD, psilocin, and DMT significantly inhibit neurotransmission, with notable effects on neuronal network activity. In a study using primary rat cortical cultures, psychedelics decreased synaptic vesicle fusion by up to 30% after 3-30 minutes of treatment. While DMT and psilocin enhanced responses at glutamatergic synapses, LSD and psilocin reduced presynaptic calcium transients. Additionally, LSD and DMT inhibited spontaneous neuronal firing without altering evoked responses. These findings deepen our understanding of how psychedelics could inform treatments for neuropsychiatric conditions.

A compelling increase in brain-derived neurotrophic factor (BDNF) was observed following low doses of LSD. In a placebo-controlled study with 30 healthy volunteers, BDNF levels rose significantly at 4 hours after a 5 μg dose and at 6 hours for both 5 μg and 20 μg doses compared to placebo. This highlights psychedelic medicine's potential for enhancing neuroplasticity, crucial for therapeutic responses in internal medicine and psychology. The biochemical analysis suggests promising avenues for future studies in psychiatric populations.

Abstract

Despite preclinical evidence for psychedelic-induced neuroplasticity, confirmation in humans is grossly lacking. Given the increased interest in us...

Updated View on the Relation of the Pineal Gland to Autism Spectrum Disorders

Frontiers in Endocrinology  – February 04, 2019

Summary

Low melatonin levels, linked to pineal gland dysfunction, may play a significant role in autism, affecting around 1 in 44 children. This hormone regulates sleep and circadian rhythms, with many autistic individuals experiencing sleep disorders. Abnormal neuroplasticity, such as cortical overgrowth, is also observed. The pineal gland could be a source of N,N-dimethyltryptamine (DMT), suggesting that both melatonin deficiency and DMT metabolism might contribute to autism's development. Exploring these connections could lead to innovative treatments involving melatonin and light exposure.

Abstract

Identification of the biological features of autism is essential for designing an efficient treatment and for prevention of the disorder. Though th...

Ayahuasca, DMT, and Mental Health: A Current Review of Scientific Studies

Current Addiction Reports  – February 21, 2026

Summary

Ayahuasca, a traditional Amazonian brew, shows promise in treating various mental health disorders, including depression and PTSD. In human studies with 60 participants, neuroimaging revealed decreased default mode network activity and increased brain connectivity, suggesting enhanced neuroplasticity. Users often report emotional breakthroughs and heightened self-awareness. While findings are encouraging, especially for addressing core psychological processes, caution is advised for individuals with psychosis or bipolar disorder. Structured trials are essential to establish the safety and efficacy of ayahuasca as a therapeutic option in clinical psychology.

Neuropharmacology of halogenated DMT analogs: psychoplastogenic and antidepressant properties of 5-Br-DMT, a psychedelic derivative with low hallucinogenic potential

Molecular Psychiatry  – October 21, 2025

Summary

A novel compound, 5-Br-DMT, shows promise as a rapid-acting antidepressant without hallucinogenic effects. In a study with mice, a single dose of 10 mg/kg significantly reduced depressive-like behavior. This compound selectively activates serotonin receptors while promoting neuroplasticity through increased expression of genes associated with dendritic growth in the prefrontal cortex and hippocampus. The findings suggest that halogenated DMT derivatives could lead to new treatments for mood disorders, addressing limitations of traditional antidepressants like SSRIs, which often fail to benefit many patients.

Abstract

Current first-line antidepressants, such as selective serotonin reuptake inhibitors (SSRI), often present a delayed onset of action and fail to eff...

Synergistic psychedelic - NMDAR modulator treatment for neuropsychiatric disorders.

Molecular psychiatry  – January 01, 2024

Summary

Combining psychedelics with specific brain receptor modulators may enhance mental health treatment while reducing unwanted effects. New findings show that psilocybin and NMDA receptor compounds like D-serine work together to boost brain plasticity and mood improvement. This dual approach could offer more effective, safer treatment options for depression and other mental health conditions.

Abstract

Modern research data suggest a therapeutic role for serotonergic psychedelics in depression and other neuropsychiatric disorders, although psychoto...

Beyond the 5-HT2A Receptor: Classic and Nonclassic Targets in Psychedelic Drug Action.

The Journal of neuroscience : the official journal of the Society for Neuroscience  – November 08, 2023

Summary

Psychedelic drugs like psilocybin and LSD work through multiple brain pathways, not just the well-known serotonin receptor system. These substances promote the formation of new neural connections and can rewire brain networks, explaining their potential benefits for mental health conditions. While their primary effects occur through serotonin receptors, they also interact with other key brain systems that influence mood and cognition. Scientists are now developing modified versions that could offer therapeutic benefits without hallucinogenic effects.

Advances in the study of NMDA receptors in depression pathogenesis and the antidepressant efficacy of their antagonists.

Asian journal of psychiatry  – June 01, 2025

Summary

Breakthrough brain research reveals why traditional antidepressants can take weeks to work, while newer treatments targeting NMDA receptors can lift severe depression within hours. These receptors, part of the brain's glutamatergic system, act like molecular switches affecting mood and memory. When blocked by specific NMDA receptor antagonists, they trigger rapid improvements in depressive symptoms, offering hope for patients who don't respond to conventional treatments.
