Not all sleep is equal when it comes to cleaning the brain

New research shows how the depth of sleep can impact our brain's ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study reinforces and potentially explains the links between aging, sleep deprivation, and heightened risk for Alzheimer's disease.

Fast, flexible ionic transistors for bioelectronic devices

Researchers have developed the first biocompatible internal-ion-gated organic electrochemical transistor (IGT) that is fast enough to enable real-time signal sensing and stimulation of brain signals. The IGT provides a miniaturized, soft, conformable interface with human skin, using local amplification to record high quality neural signals, suitable for advanced data processing. This could lead to safer, smaller, and smarter bioelectronic devices that can be implanted in humans over long periods of time.

Smoking and alcohol: Double trouble for the brain?

Along with many other harmful health consequences, smoking tobacco causes chemical changes, oxidative stress and inflammation in the brain. Excessive alcohol use can have similar effects. Surprisingly, however, very few studies have examined the combined impact of smoking and alcohol on the brain. Now, researchers have shown that in rats, the joint use of tobacco and alcohol could increase neural damage in particular brain regions.

Why environmental cues make drug addiction extra hard to beat

Besides triggering the brain's emotional and stimulus-response systems, environmental cues activate areas where memories are processed, according to this study. Prompting these memory processing systems makes it extra difficult to counter addiction because the classic stimulus-response mechanisms are reinforced by the memory effects of environmental drug cues. While this double effect makes it hard to treat drug abuse, this finding may offer a way to use cues to improve cognitive behavioural therapy.
