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

—– In the study, both (A) Total medi­al tem­po­ral lobe (MTL) and (B) parahip­pocam­pal thick­ness cor­re­lat­ed inverse­ly with hours of sitting/day, con­trol­ling for age. Ref­er­ence: Sid­darth P et al (2018), Seden­tary behav­ior asso­ci­at­ed with reduced medi­al tem­po­ral lobe thick­ness in mid­dle-aged and old­er adults. PLOS ONE 13(4): e0195549.

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 the rest of this entry »

Wearable brain scanners to enable broader, easier, cheaper access to neuroimaging

Cred­it: Uni­ver­si­ty of Not­ting­ham

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 the rest of this entry »

Can brain scans identify ADHD and help predict treatment response?

AdultADHDBrain

Inside the adult ADHD brain (MIT News):

About 11 per­cent of school-age chil­dren in the Unit­ed States have been diag­nosed with atten­tion deficit hyper­ac­tiv­i­ty dis­or­der (ADHD). While many of these chil­dren even­tu­al­ly “out­grow” the dis­or­der, some Read the rest of this entry »

Interesting Recent Studies and Articles on Neuroplasticity, Cognitive Reserve, and Brain Fitness

Here are four stud­ies and arti­cles, pub­lished in Jan­u­ary, that report very inter­est­ing find­ings and offer inspir­ing ideas:

  • An arti­cle on the role of neu­ro­plas­tic­i­ty in Rep. Gabrielle Gif­fords’ recov­ery.
  • A new study that used a blood test able to detect beta amy­loid 42 (the pro­tein frag­ment that makes up Alzheimer’s plaque) and sug­gest­ed that the asso­ci­a­tion between amy­loid and cog­ni­tive decline could be mod­i­fied by cog­ni­tive reserve.
  • An arti­cle on a new brain scan tech­nol­o­gy to detect Alzheimer’s pathol­o­gy in the brain.
  • An arti­cle report­ing the answer of Don Tap­scott to the ques­tion “What sci­en­tif­ic con­cept would improve every­body’s cog­ni­tive toolk­it?” Read the rest of this entry »
