The endocannabinoid system (ECS) plays a key role in regulating neurogenesis and inflammatory processes in the brain. The increasing prevalence of Cannabis use among women highlights the importance of understanding sex-specific effects of cannabinoids, particularly in the context of hormonal interactions. This study aimed to investigate the effects of delta-9-tetrahydrocannabinol (THC) and...

Ketamine, a non-competitive N-methyl-D-aspartate acid (NMDA) receptor antagonist, produces rapid and sustained antidepressant actions, but the underlying molecular mechanism remains unclear. The CX 3 CL1/CX 3 CR1 signaling is closely related to mood disorders, and this study aims to investigate its role in ketamine’s antidepressant actions. We pharmacologically (AZD8797, a selective CX 3 CR1...

Post-Perturbation Integrative Neuroplasticity (PPIN) is a descriptive framework for sustained, non-pathological cognitive reorganization following significant perturbation events such as severe trauma, near-death experiences, or extreme stress. Unlike acquired savant syndrome, which typically produces narrow, domain-specific skill emergence, PPIN describes broad cross-domain integration,...

Psychedelics such as psilocybin have been linked to enhanced neuroplasticity and symptom relief in affective disorders, but the neurobiological mechanisms and impact of environmental context remain unclear. Here, we tested whether a single dose of psilocybin (0.3 mg/kg) alters synaptic density in healthy individuals and whether setting-dependent subjective experience shapes this effect. Fifteen...

Neuroplasticity refers to the tendency of the nervous system to change structurally and functionally due to experience. The adult visual cortex was historically presumed rigid and unchangeable. However, recent research has identified residual neuroplasticity in the visual cortex extending into adulthood, which may be mediated by environmental factors including visual deprivation. Eagleman and...

Psilocin (4-hydroxy-N, N-dimethyltryptamine) is a substituted tryptamine alkaloid and a nonselective serotonergic agonist acting predominantly at 5-HT2A/C receptors, with substantial binding to 5-HT1A and 5-HT2B receptors. Microdosing is the practice of taking a very small, sub-perceptual dose, typically 5% to 10% of a full recreational dose, to improve mood, creativity, and focus without...

BACKGROUND: Posttraumatic stress disorder (PTSD) and major depressive disorder are often comorbid in humans. Psilocybin reportedly has beneficial therapeutic effects on depression, possibly by promoting neuroplasticity. PTSD is associated with the dysregulation of neuroplasticity in the hippocampus and medial prefrontal cortex (mPFC). We hypothesized that psilocybin might reduce fear memory by...

The brain’s ability to rewire itself, neuroplasticity, declines dramatically with age. Children learn faster; adults get stuck in patterns; older adults struggle to adapt. The reasons for this decline remain unclear. In a companion paper (Solis, 2026a), I critically evaluated the broad hypothesis that N,N-dimethyltryptamine (DMT) has endogenous physiological functions. The evidence was found to...

Ketamine has revolutionized the treatment of mood disorders by offering rapid antidepressant effects, particularly in individuals with treatment-resistant depression. Unlike traditional monoaminergic antidepressants, ketamine acts primarily through antagonism of the N-methyl-D-aspartate (NMDA) receptor, initiating a cascade of glutamatergic signaling that promotes synaptic plasticity,...

Suicide, the individual desire to take one's own life, at whose core lies the unbearable psychological pain Shneidman called psychache, is a uniquely human experience. Unlike depression, suicidality has no preclinical analog. Suicidality and chronic depression, long treated as a single clinical entity, are increasingly recognized as partly separable in neurobiology and treatment response....
