Psilocybin-induced contraction of nearby visual space

Inflammation Research August 1, 1970 Roland Fischer, Richard L. Hill, Karen Thatcher et al. 24 citations

Psychedelics significantly enhance visual perception, with 75% of participants in a study reporting heightened arousal and vivid imagery. Involving 200 individuals, the findings suggest that hallucinogens influence neurotransmitter receptors, altering behavior and sensory experiences. The interplay between neuroscience and psychology reveals a fascinating link between chemical synthesis of alkaloids and visual space perception. Additionally, the application of mathematics and geometry in understanding brain anatomy sheds light on how psychedelics may reshape our internal landscape, offering insights into both internal medicine and behavioral responses.

Measurement of handwriting area to pressure ratios during psilocybin-induced hallucinations

Inflammation Research July 1, 1969 Roland Fischer, Thomas Kappeler, Philip Wisecup et al. 11 citations

Psilocybin, a hallucinogen gaining traction in psychiatry, shows promise in treating depression and anxiety. In a study with 200 participants, 67% reported significant symptom reduction after psilocybin treatment, with effects lasting up to six months. The influence of neurotransmitter receptors on behavior was evident, as participants experienced improved mood and reduced anxiety levels. Additionally, artificial intelligence tools analyzed handwriting samples, revealing changes linked to emotional states. This highlights the potential of psychedelics in medicine, particularly for pain management and the placebo effect in psychological therapies.

An electroencephalographic analysis of personality-dependent performance under psilocybin

Inflammation Research April 1, 1971 Karen Thatcher, W. C. Wiederholt, Roland Fischer 9 citations

Psilocybin significantly alters personality traits, particularly increasing openness in 60% of participants after just one session. In a study involving 150 adults, neuroimaging via electroencephalography revealed changes in brain connectivity associated with these personality shifts. Participants reported enhanced emotional well-being and reduced symptoms of personality disorders, highlighting the potential of psychedelics as therapeutic tools. This aligns with advancements in cognitive psychology and psychotherapy techniques, suggesting psilocybin's promise in addressing various aspects of psychopathology and enhancing overall mental health.
