Researchers and clinicians have long struggled to define, measure, and treat cognitive fatigue. Nature reports on how scientists are enlisting innovative experimental approaches and biological markers to probe the metabolic roots and consequences of cognitive fatigue. #medsky 🧪

Is your brain tired? Researchers are discovering the roots of mental fatigue

Better ways to measure cognitive exhaustion could point to treatments for long COVID and other debilitating disorders.

🧠✨Excited to share my work of the last year @neuromadlab.bsky.social in collaboration with @derntllab.bsky.social! Tracking 90 adults’ glucose, hunger and #mood for 4 weeks. Interesting: In our new preprint, people with lower #interoception show higher mood variability. Have a look: 👇

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 🩺 Work w/ @kristinkaduk.bsky.social @akuehnel.bsky.social @derntllab.bsky.social www.biorxiv.org/content/10.1...

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).

Visual target and task-critical feedback uncertainty impair different stages of reach planning in motor cortex - Nature Communications

Visual uncertainty impairs reach accuracy. The authors show that uncertainty about the target always impairs cortical motor goal encoding in rhesus monkeys, while feedback uncertainty does so only whe...
