Receptor-informed network control theory links LSD and psilocybin to a flattening of the brain's control energy landscape.
Nature communications – October 03, 2022
Summary
Psychedelics like LSD and psilocybin make it easier for the brain to switch between different mental states by "flattening" the energy barriers between them. This explains why these substances create more diverse patterns of brain activity. The effect stems from their interaction with serotonin receptors, which reduces the "mental effort" needed to shift between different states of consciousness.

Ethical Issues Regarding Nonsubjective Psychedelics as Standard of Care
Cambridge Quarterly of Healthcare Ethics – October 01, 2022
Summary
A compelling finding in Psychology reveals psychedelics' therapeutic benefits largely stem from their profound subjective experiences. Although Chemical synthesis is creating "nonsubjective" compounds for individuals with specific mental illnesses, a critical ethical argument emerges for psychotherapists.

Neurovascular Uncoupling: Multimodal Imaging Delineates the Acute Effects of 3,4-Methylenedioxymethamphetamine
Journal of Nuclear Medicine – September 29, 2022
Summary
MDMA's acute effects on the brain are more complex than previously thought. In rats, this hallucinogen stimulates neuronal activity in limbic areas, key for emotional processing, increasing glucose metabolism.

Ketamine Pharmacodynamics Entangled: Reply
Anesthesiology – September 12, 2022
Summary
How Medicine categorizes powerful psychedelics like Ketamine is evolving. For over two decades, Drug Studies involving three drugs (Ketamine, cannabis, psilocybin) in patients and healthy volunteers revealed similar mind-altering effects. Traditional Anesthesia and Pharmacology terms like "dissociation," or focusing on a single Neurotransmitter Receptor, prove insufficient. A new Pharmacodynamics term, "psychoplastogen," is proposed. This describes molecules promoting rapid neural plasticity in the cortex, explaining their healing mechanisms for Treatment of Major Depression, beyond subjective experiences.

Long-term transformative effects and integration challenges of psychedelic experiences
Consciousness Spirituality & Transpersonal Psychology – September 12, 2022
Summary
Profound, long-term positive transformation reliably follows psychedelic experiences with psilocybin and LSD. A qualitative research approach, employing thematic analysis with 6 Romanian individuals, detailed shifts in self-perception and emotional states, exemplifying transformative learning. Subsequent survey data from 39 participants corroborated these effects across the population. Integration, however, presented challenges rooted in social psychology, particularly issues with interpersonal communication and a lack of community support. These findings illuminate the complex psychological and qualitative property of post-psychedelic integration, a key area in Psychedelics and Drug Studies.
