1. REM Sleep Metabolism

This story is about an energy paradox during REM sleep, based on a paper in Communications Biology. The researchers describe how the sleeping brain can show high energy demand even while some measures of energy supply appear constrained.

2. PTSD Astrocytes

This story is about a proposed astrocyte mechanism in PTSD, from a 2025 paper in Signal Transduction and Targeted Therapy. The authors combined human imaging, post-mortem tissue, and a mouse model to argue that reactive astrocytes increase MAO-B activity and tonic GABA in medial prefrontal cortex.

3. Amanita EEG

This story is about an exploratory human EEG recording during Amanita muscaria use, shared through a GitHub research project. The investigator used a consumer Muse headset with four sensors and compared one mushroom night with a control night.
