Beacon Biosignals raises $27M to scale EEG, AI-based neurobiomarker discovery platform

Neu­rotech start­up Bea­con Biosig­nals scores $27M to bring AI to EEG analy­sis (Med­C­i­ty News):

Elec­troen­cephalog­ra­phy is a decades-old tech­nique for cap­tur­ing brain activ­i­ty, data that are used to eval­u­ate brain dis­or­ders. Bea­con Biosig­nals is apply­ing arti­fi­cial intel­li­gence to these tests, and the neu­rotech­nol­o­gy start­up has found a ready mar­ket in phar­ma­ceu­ti­cal com­pa­nies inter­est­ed in assess­ing how their exper­i­men­tal brain ther­a­pies are work­ing. Now Bea­con Biosig­nals has some­thing else: $27 mil­lion in financ­ing. [Read more…] about Bea­con Biosig­nals rais­es $27M to scale EEG, AI-based neu­ro­bio­mark­er dis­cov­ery platform

Becoming better mind-wanderers to boost problem-solving and mood

by

I’m a big believ­er in day­dream­ing now and then—especially when I’m out hik­ing. There’s some­thing about being in nature that helps me let go of dai­ly cares and allows my mind to wan­der where it will, which feels great and often jump­starts my cre­ativ­i­ty as a writer and musician.

I admit, though, I’ve been trou­bled by research show­ing how mind-wan­der­ing could make me less pro­duc­tive or depressed—the last thing I need! But it turns out this gap between per­son­al expe­ri­ence and sci­ence may best be explained by how researchers have lumped togeth­er dif­fer­ent kinds of mind-wan­der­ing. Not all research has dif­fer­en­ti­at­ed between depres­sive rumi­na­tion (like replay­ing an ongo­ing dis­agree­ment with our spouse in our minds) and pleas­ant day­dream­ing (let­ting our minds wan­der freely).

The per­ils of open­ing the mind (Boston Globe):

“For­get the joy­stick. Today you can use your mind alone to nav­i­gate vir­tu­al envi­ron­ments or fly real-world drones. You can buy sleek head­bands that read your brain sig­nals and help you med­i­tate or stay focused. Or you can get them for your kids to make sure they’re work­ing, not day­dream­ing [Read more…] about Let’s antic­i­pate the poten­tial mis­use of neu­ro­log­i­cal data to min­i­mize the risks–and max­i­mize the benefits

Machine-learning study finds EEG brain signatures that predict response to antidepressant treatments

Brain-wave pat­tern can iden­ti­fy peo­ple like­ly to respond to anti­de­pres­sant, study finds (Stan­ford Med­i­cine press release):

“A new method of inter­pret­ing brain activ­i­ty could poten­tial­ly be used in clin­ics to help deter­mine the best treat­ment options for depres­sion, accord­ing to a study led by researchers at the Stan­ford School of Medicine.

Stan­ford researchers and their col­lab­o­ra­tors used elec­troen­cephalog­ra­phy, a tool for mon­i­tor­ing elec­tri­cal activ­i­ty in the brain, and an algo­rithm to iden­ti­fy a brain-wave sig­na­ture in [Read more…] about Machine-learn­ing study finds EEG brain sig­na­tures that pre­dict response to anti­de­pres­sant treatments

Wear­able brain devices sold with ques­tion­able claims (Com­put­er World):

“Wear­able ‘neu­rotech­nol­o­gy’ devices have in recent years hit the main­stream mar­ket; pitched to con­sumers as a way to improve mem­o­ry and atten­tion, boost brain fit­ness and con­trol games and objects with the pow­er of the mind.

An analy­sis of com­mer­cial­ly avail­able wear­able ‘neu­rode­vices’ pub­lished this week in jour­nal Neu­ron has cast doubt on whether their mak­ers can back up such claims.
