Combined tDCS neurostimulation and cognitive training found to improve working memory among older adults–especially those with lower starting capacity

Giv­ing mem­o­ry a lift: Can games and brain stim­u­la­tion do it? (Med­ical­New­sTo­day):

A person’s work­ing mem­o­ry may decline with age or if they have demen­tia, Parkinson’s dis­ease, or have had a stroke. When this occurs, the loss can affect their day-to-day qual­i­ty of life, turn­ing even sim­ple tasks into often-demor­al­iz­ing chal­lenges.

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.

Q&A with Dr. Wendy Suzuki on the parasympathetic nervous system and harnessing anxiety for good

by

Anx­i­ety can feel like a heavy weight that we didn’t ask to car­ry. Who wouldn’t love to get rid of it?

But neu­ro­sci­en­tist Wendy Suzu­ki wants to chal­lenge the way we look at our anx­i­ety. In fact, her new book is called Good Anx­i­ety: Har­ness­ing the Pow­er of the Most Mis­un­der­stood Emo­tion.

If you’re skep­ti­cal, so was I. But Suzuki’s point is that anx­i­ety is a nat­ur­al human emo­tion, one that evolved to serve a pur­pose. We feel anx­ious when there is some kind of dan­ger; it primes our body to fight or flee from that dan­ger, in hopes that we’ll end up bet­ter off (i.e., alive). In the same way, our mod­ern anx­i­eties can be a warn­ing sig­nal for things that are wrong: not enough rest, too much mul­ti­task­ing, iso­la­tion from oth­ers. Our anx­ious ener­gy alerts us to change our lives for the bet­ter, she argues.

The frontal lobes, the little brain down under and “Stayin’ Alive” (3/3)

[Editor’s note: Con­tin­ued from Explor­ing the human brain and how it responds to stress (1/3) and On World Health Day 2020, let’s dis­cuss the stress response and the Gen­er­al Adap­ta­tion Syn­drome (2/3)]

More on the Cor­tex, the Lim­bic Sys­tem, and Stress:

The cor­tex is made up of four major sec­tions, arranged from the front to the back. These are called the frontal, pari­etal, occip­i­tal, and tem­po­ral lobes. Each of the four lobes is found in both hemi­spheres, and each is respon­si­ble for dif­fer­ent, spe­cial­ized cog­ni­tive func­tions. For exam­ple, the occip­i­tal lobe con­tains the pri­ma­ry visu­al cor­tex, and the tem­po­ral lobe (locat­ed by the tem­ples, and close to the ears) con­tains the pri­ma­ry audi­to­ry cortex.

The frontal lobes are posi­tioned at the front most region of the cere­bral cor­tex and are involved in move­ment, deci­sion mak­ing, prob­lem solv­ing, and plan­ning. There are [Read more…] about The frontal lobes, the lit­tle brain down under and “Stayin’ Alive” (3/3)
