🧠💤 While we sleep, the brain isn’t just resting - it’s choosing.

Sleep strengthens the memories we decide to keep. Top-down control beats emotional salience every night. 🌙

Do you get in a bad mood if you are hungry? Over 4 weeks with EMA+CGM, we tested if mood shifts are subconsciously driven by glucose levels or ratings of metabolic state #neuroskyence 🩺

Summary of the study. A: The schematic shows the experimental procedure, illustrating five weekly lab visits followed by 2 MR visits labeled from S1 to S7. After the first session (S1), participants undergo four weeks of continuous glucose monitoring (CGM) combined with ecological momentary assessment (EMA). B: The CGM system uses a small flex sensor placed at the posterior upper arm that is inserted in the subcutaneous fatty tissue. The glucose sensor, positioned beneath the skin surface layers (epidermis and dermis), measures glucose levels in the interstitial fluid within the subcutaneous adipose tissue. The data is wirelessly sent via near field communication (NFC) to the FreeStyle Libre 3 app on the participant’s cell phone. The accuracy of the sensor concerning capillary glucose has been validated (Alva et al., 2022). C: Participants rate their metabolic and mood states twice daily using a visual analog scale (VAS), ranging from 0 (not at all) to 100 (very).

A 4-day working week boosts sleep *and* work performance. What are we waiting for? 🙌
www.cell.com/trends/cogni...
How can a 4-day working week increase wellbeing at no cost to performance?
The 4-day working week is gaining interest, with international trials reporting enhanced staff wellbeing and performance, despite spending less time on the job. Here, we argue that improved performance on a 4-day working week arises through two psychological mechanisms of recovery and motivation: because better rested, better motivated brains, create better work.

An orange-blue sunset triggers melatonin (and #sleep), but indoor lights keep people up.

This small NIH-sponsored study developed a light that advances melatonin 1.3 hours by replicating those colors, turning night owls into natural sleepers:

ADHD is associated with a high risk of suicide across sexes and all ages. This risk is decreased by treating with meds: methylphenidate/amphetamines (aka ritalin/adderall). The protective effect is seen in children, adults, and veterans. (references below)
