Loss of empathy in frontotemporal dementia linked to brain activity changes

Patients with frontotemporal dementia often lack the ability to empathize. A study at Karolinska Institutet has now shown that these patients do not show the same brain activity as healthy individuals when they witness the pain of others, a finding that it is hoped will increase understanding of this specific dementia disease.

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.
