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…

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…

Can COVID-19 coronavirus “invade” human brain tissue? (Quick answer: evidence so far is mixed)

Tak­ing a Clos­er Look at COVID-19’s Effects on the Brain (NIH Direc­tor’s blog): While pri­mar­i­ly a res­pi­ra­to­ry dis­ease, COVID-19 can also lead to neu­ro­log­i­cal prob­lems. The first of these symp­toms might be the loss of smell and taste, while some peo­ple also may lat­er bat­tle headaches, debil­i­tat­ing fatigue, and trou­ble think­ing clear­ly, some­times referred to as…

Understanding Brain Health via Cosmological Health, and vice versa

Neu­ro­science Meets Astro­physics: Does the Human Brain Resem­ble the Uni­verse? (SciTech­Dai­ly): In their paper pub­lished in Fron­tiers of Physics, Fran­co Vaz­za (astro­physi­cist at the Uni­ver­si­ty of Bologna) and Alber­to Felet­ti (neu­ro­sur­geon at the Uni­ver­si­ty of Verona) inves­ti­gat­ed the sim­i­lar­i­ties between two of the most chal­leng­ing and com­plex sys­tems in nature: the cos­mic net­work of galaxies…

Explore The State of Noninvasive Neurotechnology in 37 minutes and 1 image

? Heads-up: The record­ings for the webi­nar on The State of Non­in­va­sive Neu­rotech­nol­o­gy, held on May 19th, are already avail­able on YouTube. Dr. Ricar­do Gil-da-Cos­­ta (above) and Alvaro Fer­nan­dez (below) gave an excel­lent out­look on the brain tech indus­try, with a deep look into apps and wear­ables and the capa­bil­i­ties that human brain could achieve.…
