Cannabis Perturbs Dynamic Brain States

Biological Psychiatry October 21, 2025 Katharina S Lege, Pablo Mallaroni, Sepehr Mortaheb et al. 1 citation

Background The impact of acute cannabis exposure on brain function and cognitive performance varies among individuals. Acute effects of cannabis on behavior may be absent or benign in chronic users, while occasional users experience significant impairment in day-to-day operations. It is hypothesized that repeated cannabis use induces neuroadaptations leading to tolerance and desensitization,...

Dynamic Functional Hyperconnectivity After Psilocybin Intake Is Primarily Associated With Oceanic Boundlessness.

Biological psychiatry. Cognitive neuroscience and neuroimaging July 1, 2024 Sepehr Mortaheb, Larry D. Fort, Natasha L. Mason et al. 15 citations

Psilocybin is a widely studied psychedelic substance that leads to the psychedelic state, a specific altered state of consciousness. To date, the relationship between the psychedelic state's neurobiological and experiential patterns remains undercharacterized because they are often analyzed separately. We investigated the relationship between neurobiological and experiential patterns after...

Study protocol: Cerebral characterization of sensory gating in disconnected dreaming states during propofol anesthesia using fMRI

Frontiers in Neuroscience February 13, 2024 Benedetta Cecconi, Javier Montupil, Sepehr Mortaheb et al. 6 citations
