How do structural connectivity and conduction speed shape the development of brain oscillations? In @NSR_Family, we introduce ξ–αNET, a model linking the connectome and interareal delays to aperiodic and alpha rhythms. @sosa_valdes doi.org/10.1093/nsr/nw…

It’s time to rethink Parkinson’s disease. Our work reframes PD as a disorder of the somato-cognitive action network (SCAN), and shows that normalization of SCAN connectivity represents a shared mechanism across diverse effective therapies. nature.com/articles/s4158… @ndosenbach

3.6h/day of phone use is linked to less brain volume and activity in your salience network. This network helps you: - decide what's worth your attention - regulate emotional responses - resist impulses

This network helps you:
- decide what&apos;s worth your attention
- regulate emotional responses

This is one of the most important studies in sleep science. Van Dongen et al. ran the experiment that changed how we understand chronic sleep restriction. They had subjects sleep 4h, 6h, or 8h nightly for 14 days, testing cognitive performance every 2 hours. The 6h group’s…

Competitive gamers: 6h of sleep is a hidden nerf. 6h/night for 2 weeks → reaction time & attention decline to the equivalent of pulling MULTIPLE all-nighters. Worst part: subjective fatigue plateaus, so you stop noticing. If you're not getting 7+ hours/night, you're trolling.
