Cortisol’s Role in PTSD Vulnerability

Researchers discovered how stress-induced hormones like cortisol influence the likelihood of developing PTSD. Using a rat model with a blunted hormonal response to stress, they observed impaired fear extinction, reduced hippocampal volume, and sleep disturbances, all traits associated with PTSD.

Taming the Flame of Aging: Key Pathway for Chronic Inflammation Revealed

Researchers have unveiled the key role of the cGAS/STING molecular signaling pathway in driving chronic inflammation and functional decline during aging. The team discovered that blocking the STING protein suppressed inflammatory responses in aging cells and tissues, leading to improved function.

Early Hallucinations in Parkinson’s Tied to Faster Cognitive Decline

Early hallucinations in Parkinson's disease patients might signal a faster cognitive decline. Through comprehensive neuropsychological interviews and electroencephalography measurements, researchers were able to link minor hallucinations, typically underreported, to more rapid deterioration of frontal executive function in subsequent years.

Wireless Brain-Spine Interface: A Leap Towards Reversing Paralysis

In a pioneering study, researchers designed a wireless brain-spine interface enabling a paralyzed man to walk naturally again. The 'digital bridge' comprises two electronic implants — one on the brain and another on the spinal cord — that decode brain signals and stimulate the spinal cord to activate leg muscles.

Amputees Sense Temperature in Missing Limbs

A new study reveals amputees can feel temperature in their phantom limbs using thermal electrodes placed on their residual arms. Participants in the study reported feeling heat or cold, and discerning material types, such as copper, plastic, or glass.

Machine-Learning Algorithm Predicts What Mice See From Brain Data

EPFL researchers have developed a novel machine learning algorithm called CEBRA, which can predict what mice see based on decoding their neural activity. The algorithm maps brain activity to specific frames and can predict unseen movie frames directly from brain signals alone after an initial training period. CEBRA can also be used to predict movements of the arm in primates and to reconstruct the positions of rats as they move around an arena, suggesting potential clinical applications.

Motivation Is Affected by Oxidative Stress, but Nutrition Can Help

Higher levels of glutathione in the nucleus accumbens correlated with better and more steady performance in motivation-based tasks. Findings suggest improvements in accumbal anti-oxidant function that can be acquired via diet or supplementation may be a feasible approach to help boost motivation.
