Neuroscience Daily for 20 August follows 3 stories from r/neuro and r/neuroscience, moving through rem sleep metabolism, ptsd astrocytes, amanita eeg.

Chapters

• 00:00:00 — Intro
• 00:00:08 — REM Sleep Metabolism
• 00:01:03 — PTSD Astrocytes
• 00:02:03 — Amanita EEG
• 00:03:07 — Closing

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.

Neuroscience Daily for 19 August follows 3 stories from r/neuro and r/neuroscience, moving through efficient coding, dopamine dips, semaglutide hunger circuit.

Chapters

• 00:00:00 — Intro
• 00:00:10 — Efficient Coding
• 00:01:08 — Dopamine Dips
• 00:02:07 — Semaglutide Hunger Circuit
• 00:03:14 — Closing

1. Efficient Coding

This story is about a bioRxiv preprint asking why Weber's law appears so reliably in perception. Weber's law says that the smallest noticeable change in a stimulus tends to scale with the size of that stimulus.

2. Dopamine Dips

This story is about a bioRxiv mouse study on dopamine dips and punishment-resistant reward seeking. The researchers studied a behavior associated with addiction, where an animal keeps pursuing a reward even when the action carries a cost.

3. Semaglutide Hunger Circuit

This story is about a PNAS study on how semaglutide recruits AgRP hunger neurons in female mice. AgRP neurons are usually associated with hunger, low energy availability, and energy conservation, so researchers have often expected GLP-1 drugs to suppress or bypass them.

Neuroscience Daily for 18 August follows 3 stories from r/neuro and r/neuroscience, moving through ect medication response, vestibular adaptation, neuroplasticity claims.

Chapters

• 00:00:00 — Intro
• 00:00:14 — ECT Medication Response
• 00:01:10 — Vestibular Adaptation
• 00:02:08 — Neuroplasticity Claims
• 00:02:47 — Closing

1. ECT Medication Response

This story is about whether electroconvulsive therapy, or ECT, can help psychiatric medications work again, based on a post on r/neuro. The post shares a video called and presents the idea that ECT may create a biological substrate that makes later medication more effective.

2. Vestibular Adaptation

This story is about a horse rider performing rapid changes in body position, in a video shared on v.redd.it. The post asks whether repeated riding maneuvers could adapt the vestibular system, which helps the brain track head motion and orientation.

3. Neuroplasticity Claims

This story is about a Substack post presenting neuroplasticity as a life-changing idea. It argues broadly that the brain can change through experience, practice, and behavior, but provides no study, experiment, or measurable result.
