Large neuroimaging study finds social isolation to be an early indicator of increased dementia risk

Why do we get a buzz from being in large groups at fes­ti­vals, jubilees and oth­er pub­lic events? Accord­ing to the social brain hypoth­e­sis, it’s because the human brain specif­i­cal­ly evolved to sup­port social inter­ac­tions. Stud­ies have shown that belong­ing to a group can lead to improved well­be­ing and increased sat­is­fac­tion with life. Unfor­tu­nate­ly though, many…

Collaborative neuroimaging initiative BrainChart helps chart how brains change across the lifespan

For decades, growth charts have been used by pae­di­a­tri­cians as ref­er­ence tools. The charts allow health pro­fes­sion­als to plot and mea­sure a child’s height and weight from birth to young adult­hood.

On brain folding and fitting 86 billion neurons inside our 1400 cc crania

The human brain has been called the most com­plex object in the known uni­verse. And with good rea­son: It has around 86 bil­lion neu­rons and sev­er­al hun­dred thou­sand miles of axon fibers con­nect­ing them. Unsur­pris­ing­ly, the process of brain fold­ing that results in the brain’s char­ac­ter­is­tic bumps and grooves is also high­ly com­plex. Despite decades of…
