New Study Brings Bio­mark­ers For Depres­sion Clos­er To The Clin­ic (Forbes):

Sci­en­tists have been study­ing bio­log­i­cal signs of depres­sion in the brain, look­ing for mark­ers that could be used to iden­ti­fy the dis­or­der. A team of sci­en­tists recent­ly devel­oped a tech­nique using machine learn­ing that can iden­ti­fy whether a giv­en patien­t’s brain scan shows one of depres­sion’s neur­al sig­na­tures [Read more…] about Machine learn­ing study finds stan­dard­ized brain scan bio­mark­er to detect depres­sion with 66% accuracy

The more hours you sit per day, the smaller your medial temporal lobe (MTL) seems to become, brain scans show

Sit­ting is bad for your brain — not just your metab­o­lism or heart (UCLA release):

“UCLA researchers recruit­ed 35 peo­ple ages 45 to 75 and asked about their phys­i­cal activ­i­ty lev­els and the aver­age num­ber of hours per day they spent sit­ting over the pre­vi­ous week. Each per­son had a high-res­o­lu­tion MRI scan, which pro­vides a detailed look at the medi­al tem­po­ral lobe, or MTL, a brain region involved in the for­ma­tion of new memories.

The researchers found that seden­tary behav­ior is a sig­nif­i­cant pre­dic­tor of thin­ning of the MTL and [Read more…] about The more hours you sit per day, the small­er your medi­al tem­po­ral lobe (MTL) seems to become, brain scans show

This Brain Scan­ner Is Way Small­er Than fMRI but Some­how 1,000% Creepi­er (Giz­mo­do):

“It may look like some­thing befit­ting Halloween’s Michael Myers, but the device pic­tured above is actu­al­ly a break­through in neuroscience—a portable, wear­able brain scan­ner that can mon­i­tor neur­al activ­i­ty while a per­son is mov­ing [Read more…] about Wear­able brain scan­ners to enable broad­er, eas­i­er, cheap­er access to neuroimaging

Can brain scans identify ADHD and help predict treatment response?
