An exploration of the relationships between the effects of psilocybin on behavior, 5-HT 2A receptor occupancy, and neuroplastic effects in mice
Journal of Psychopharmacology – January 06, 2026
Summary
Psilocybin, a potent hallucinogen, offers rapid antidepressant effects. Neuroscience reveals this medicine's pharmacology involves dose-dependent 5-HT2A receptor occupancy (RO₅₀ = 0.88 mg/kg). In mice, a 3 mg/kg dose reduced immobility in a behavioural despair test 24 hours later, while 1.5 mg/kg showed anxiolytic-like effects. Peak acute effects occurred between 44% and 62% receptor occupancy. These psychedelics enhance neuroplasticity, specifically synaptic plasticity, in the prefrontal cortex, not the amygdala. This suggests psilocybin's therapeutic psychology benefits stem from region-specific neuronal rewiring, influencing behavior.

Functional Plasticity in Auditory and Visual Discrimination Processing in Patients with Single-Sided Deafness: An EEG Study.
Trends in hearing – January 01, 2026
Summary
The brains of individuals with single-sided deafness (SSD) show distinct cross-modal plasticity. Examining 37 SSD patients and 32 normal-hearing controls with EEG during an oddball paradigm, early auditory event-related potentials were reduced, while early visual responses were heightened. This indicates that partial auditory deprivation leads to compensatory visual activity, predominantly at lower sensory processing stages. Crucially, higher-level discrimination abilities remain unaffected in both modalities. This provides a clearer understanding of how the brain adapts to sensory loss.

Preadministration of Lorazepam Negates the Long-Term Antidepressant-Like Effects of Psilocybin in Male Wistar Kyoto Rats
Psychedelic Medicine – December 16, 2025
Summary
Psilocybin demonstrates lasting antidepressant effects, persisting for up to 9 weeks in tested rats. In a study with male Wistar Kyoto rats (n=40), those receiving psilocybin alone showed significant improvements compared to controls. However, when lorazepam was administered prior to psilocybin, no antidepressant benefits were observed.

Psilocybin in late-life mental health: Addressing depression, loneliness, and existential anxiety
General Hospital Psychiatry – December 09, 2025
Summary
Psilocybin therapy holds significant promise for addressing late-life mental health conditions like depression and loneliness, where traditional treatments often falter. Clinical trials in general adult populations show sustained improvements in depressive symptoms, existential anxiety, and social connectedness, linked to enhanced brain flexibility and serotonin pathways. However, older adults are notably underrepresented in psychedelic exploration, creating critical gaps in understanding optimal dosing, safety profiles, and long-term outcomes for this demographic. Tailored protocols are essential given age-related physiological changes and potential drug interactions.

Psilocybin triggers an activity-dependent rewiring of large-scale cortical networks
Cell – December 05, 2025
Summary
A single dose of psilocybin dramatically reconfigures brain connections, offering new insights into its therapeutic potential. In mice, psilocybin specifically strengthens communication pathways from areas involved in perception and self-reflection to deeper brain regions. Simultaneously, it weakens connections within repetitive cortical loops. This targeted rewiring, involving structural changes in brain cells, depends on brain activity during drug administration; silencing specific areas prevents the reorganization. These findings illuminate how psychedelics reshape large-scale brain networks, suggesting that modulating brain activity can guide psilocybin's profound effects.

Psychedelics as neuroplasticity enhancers: Mechanisms, therapeutic applications, and translational challenges
Advanced Neurology – December 04, 2025
Summary
Psychedelics like psilocybin and ketamine show remarkable potential in enhancing neuroplasticity, crucial for treating neuropsychiatric disorders. In clinical settings, 60-80% of participants with depression or PTSD reported significant symptom relief when these substances were combined with psychotherapy. These compounds primarily interact with serotonergic and glutamatergic systems, promoting rapid synaptogenesis and changes in brain connectivity. However, challenges regarding safety and the translation of findings into clinical practice remain. Addressing ethical and legal issues is essential for integrating these therapies into modern psychiatric care.

Psilocybin Maintains Better Brain Function in an Alzheimer’s Disease Model with Reduced Neuroinflammation and Improved Hippocampal Neurogenesis
Alzheimer s & Dementia – December 01, 2025
Summary
Psilocybin significantly improved cognitive and mood functions, including anhedonia, in an Alzheimer's disease model. Mice treated monthly for four months showed enhanced pattern separation and recognition memory. Neuroscience links psilocybin to reduced neuroinflammation, specifically microglial inflammasome activity, and enhanced hippocampal neurogenesis within the hippocampal formation. 16 proteins crucial for neuroplasticity and synapse maintenance were upregulated. This medicine offers a pathway for treating cognitive decline and disease pathogenesis, distinct from amyloid-beta plaque reduction, impacting brain health.
