General Knowledge Level Is Associated With Structural Brain Network Connectivity

An individual’s level of general knowledge is associated with structural brain network connectivity, neuroscientists at Ruhr-Universität Bochum and Humboldt-Universität zu Berlin have shown. “Although we can precisely measure the general knowledge of people, and this wealth of knowledge is very important for an individual’s journey through life, we currently know little about the links between […]

Noradrenaline Reconfigures Functional Brain Connections During Stress

Selective release of the neurotransmitter noradrenaline reconfigures communication between large-scale networks in the brain, researchers at ETH Zurich have shown for the first time. The findings bring insight into speedy neural processes that happen in the brain in stressful situations. In moments of acute stress — for example, a life-threatening situation in road traffic — […]

Brains Work In Sync During Music Therapy

The brains of a patient and therapist become synchronised during a music therapy session, a study from researchers at Anglia Ruskin University has demonstrated. The finding could improve future interactions between patients and therapists. This is the first music therapy study to use a procedure called hyperscanning, which records activity in two brains at the […]

Dendrites Are Unexpectedly Active In Neural Computation

Most neurons have many branching extensions called dendrites that receive input from thousands of other neurons. Dendrites aren’t just passive information-carriers, however. According to a new study from MIT, they appear to play a surprisingly large role in neurons’ ability to translate incoming signals into electrical activity. Neuroscientists had previously suspected that dendrites might be […]

New Brain Mapping Technique Reveals How Information Is Processed

A novel technique for rapidly mapping the epic network of connections between neurons in the brain has been developed by researchers. Infrared laser stimulation techniques were combined with functional magnetic resonance imaging in animals to generate mapping of connections throughout the brain. “This is a revolution in detecting connections in the brain. The ability to […]
