The Phi Complex as a neuromarker of human social coordination

Researchers from Florida Atlantic University (FAU) have been able to identify neural signatures of effective, real-time coordination between people in one of the first studies in the field of social neuroscience to actually record, measure and analyze both behavior and brain activity simultaneously in two interacting humans.

New compounds promising candidates for neurodegenerative disease drug development

Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease.

Multitasking mental cells

In the mid-1990s, scientists at the University of Parma, in Italy, made a discovery so novel that it shifted the way psychologists discuss the brain. After researchers implanted electrodes into the heads of monkeys, they noticed a burst of activity in the premotor cortex when the animals clutched a piece of food.
