Psychedelic use can intensify psychological distress, especially for women with public health care. Analyzing data from 484,732 individuals reveals private health insurance links to lower distress, while public coverage correlates with higher distress. For women, psilocybin and LSD use reinforced lower distress with private insurance but significantly heightened distress with public health care. This behavior suggests psychedelics interact with existing healthcare access, failing to mitigate structural inequalities in clinical psychology and potentially worsening outcomes.

Background: Structural inequalities in healthcare access may influence how individuals experience the psychological effects of psychedelic substanc...

Emotion, Motivation, Reasoning, and How Their Brain Systems Are Related.

Brain sciences  – May 16, 2025

Summary

The intricate dance between emotion and motivation in our brains reveals how we pursue rewards and avoid threats. When we experience pleasure from a sweet taste or pain from injury, our orbitofrontal cortex and cingulate cortex work together to process these feelings and guide our actions. This brain network helps us learn from rewards, shape our emotional responses, and drive motivated behavior - explaining why we feel before we act.

Abstract

A unified theory of emotion and motivation is updated in which motivational states are states in which instrumental goal-directed actions are perfo...

Participant experiences of icaros (Amazonian curative songs) during a traditional medicine ceremony at the Takiwasi Center, Peru

Journal of Psychedelic Studies  – May 15, 2025

Summary

Curative songs, or icaros, significantly enhance healing in Amazonian traditional medicine, particularly during ayahuasca ceremonies. Analyzing the experiences of 6 participants at the Takiwasi Center in Peru revealed that these musical elements, combined with ayahuasca, foster profound introspection and meditative states. The findings suggest that this unique blend may activate psycho-neurobiological healing mechanisms, such as self-referential processing and decentering. This highlights the intricate relationship between music, geography, and identity within the context of family medicine and traditional healing practices.
