Hairlike electrodes offer a new era for comfortable EEG monitoring

The future of electroencephalography (EEG) monitoring may soon look like a strand of hair. In place of the traditional metal electrodes, a web of wires and sticky adhesives, a team of researchers from Penn State created a hairlike device for long-term, non-invasive monitoring of the brain's electrical activity.

Caffeine increases brain complexity during sleep and shifts it toward a critical state

Caffeine shifts brain activity during sleep by increasing EEG complexity and reducing long-range temporal correlations, particularly in non-REM (NREM) sleep. These changes reflect a movement toward a “critical regime” of neural processing, more pronounced in younger adults.

Noninvasive decoder could help restore movement after spinal cord injury

When a person sustains an injury to the spinal cord, the normal communication between the brain and the spinal circuits below the injury are interrupted, resulting in paralysis.

Multidimensional sleep health linked to better cardiometabolic outcomes

Healthy sleep includes multiple components, such as number of hours of sleep per night, how long it takes to fall asleep, daytime functioning and self-reported sleep satisfaction, and addressing these different dimensions of sleep may help to reduce cardiometabolic health and related risk factors, according to a new American Heart Association scientific statement published today in Circulation: Cardiovascular Quality and Outcomes.

Biocompatible liquid ink enables scalp-printed electrodes for non-invasive EEG

For the first time, scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology, presented December 2 in the Cell Press journal Cell Biomaterials, offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.
