Study finds that playing videogames may be more cognitively beneficial for children than other forms of screentime (social media, watching videos/ TV)

by

Many par­ents feel guilty when their chil­dren play video games for hours on end. Some even wor­ry it could make their chil­dren less clever. And, indeed, that’s a top­ic sci­en­tists have clashed over for years.

In our new study, we inves­ti­gat­ed how video games affect the minds of chil­dren, inter­view­ing and test­ing more than 5,000 chil­dren aged ten to 12. And the results, pub­lished in Sci­en­tif­ic Reports, will be sur­pris­ing to some.

How ’sleeping on it’ can help the prefrontal cortex regulate emotional responses, making us feel better in the morning

by

Instead of lying awake wor­ry­ing, we’re often told to “sleep on it” when mak­ing deci­sions both big and small. And there’s actu­al­ly a sci­en­tif­ic basis for this advice. Sleep can influ­ence our response to emo­tion­al sit­u­a­tions, and helps us to man­age our men­tal health.

To under­stand why sleep and emo­tions are so con­nect­ed, it’s impor­tant to first under­stand what hap­pens in the brain when we encounter some­thing emo­tive.

Study on the “ABCs of Mental Health” finds that simply believing you can improve mental wellbeing helps actually improve it

by

The num­ber of peo­ple strug­gling with poor men­tal health and men­tal dis­or­ders has been ris­ing around the world over the past few decades. Those who are strug­gling are increas­ing­ly fac­ing dif­fi­cul­ties access­ing the kind of sup­port they need – leav­ing many wait­ing months for help, if they even qual­i­fy for treatment.

While it’s clear that more needs to be done to improve access to treat­ment, it doesn’t mean peo­ple inevitably have to strug­gle with their men­tal health as a result. In fact, there are many things peo­ple can do on their own to main­tain good men­tal health – and even pre­vent men­tal health prob­lems from devel­op­ing in the first place. Accord­ing to our recent research, one of the steps you can take to improve your men­tal well­be­ing may be as sim­ple as believ­ing that you can.

In our recent study, we asked 3,015 Dan­ish adults to fill out a sur­vey that asked ques­tions about men­tal health – such as whether they believe they can do some­thing to keep men­tal­ly healthy, whether they had done some­thing in the past two weeks to sup­port their men­tal health, and also whether they were cur­rent­ly strug­gling with a men­tal health prob­lem. We then assessed their lev­el of men­tal well­be­ing using the Short Warwick–Edinburgh Men­tal Well-being Scale, which is wide­ly used by health­care pro­fes­sion­als and researchers to mea­sure men­tal well­be­ing.

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. The per­centile scores they pro­vide, espe­cial­ly across mul­ti­ple vis­its, help doc­tors screen for con­di­tions such as obe­si­ty or inad­e­quate growth, which fall at the extremes of these scores.

Mean­while, it is pos­si­ble to mea­sure brain devel­op­ment with imag­ing tech­nolo­gies such as ultra­sound, mag­net­ic res­o­nance imag­ing (MRI) and com­put­erised tomog­ra­phy (CT). The devel­op­ment of these tech­nolo­gies has led to a wealth of research on how the brain changes, and each year, mil­lions of clin­i­cal brain scans are per­formed world­wide. Despite this progress, there are few mea­sures that are used to aid in mon­i­tor­ing brain devel­op­ment. Why?

Mapping ‘psychedelic trips’ in the brain to better direct their therapeutic effects

For the past sev­er­al decades, psy­che­delics have been wide­ly stig­ma­tized as dan­ger­ous ille­gal drugs. But a recent surge of aca­d­e­m­ic research into their use to treat psy­chi­atric con­di­tions is spurring a recent shift in pub­lic opinion.

Psy­che­delics are psy­chotrop­ic drugs: sub­stances that affect your men­tal state. Oth­er types of psy­chotrop­ics include anti­de­pres­sants and anti-anx­i­ety med­ica­tions. Psy­che­delics and oth­er types of hal­lu­cino­gens, how­ev­er, are unique in their abil­i­ty to tem­porar­i­ly induce intense hal­lu­ci­na­tions, emo­tions and dis­rup­tions of self-aware­ness.

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 spec­u­la­tion and research, the under­ly­ing mech­a­nism behind this process remains poor­ly under­stood. As bio­me­chan­ics and com­put­er sci­ence researchers, we have spent sev­er­al years study­ing the mechan­ics of brain fold­ing and ways to visu­al­ize and map the brain, respec­tive­ly.
