After only a few minutes of activity, the physical activity stimulates the production of new nerve cells and the formation of new brain links. (slideshare.net)
Does Physical Activity Lead to Higher Grades? (voanews.com)
Researcher Amika Singh says the studies showed a link between physical activity and scores on subjects such as math, English and reading. (voanews.com)
Her Amike Singh's paper on 'Physical Activity and Performance at School' is published in the Archives of Pediatric and Adolescent Medicine. (voanews.com)
However, little is known about the brain adaptations to physical activity. (bvsalud.org)
Physical specialists perform interventive treatments like back rub, needle therapy, activities and manual treatments to improve the working of the body. (brainhealthconsulting.com)

There were minimal sex differences in brain activation across the isometric motor tasks indicating men and women were similarly motivated and able to activate cortical motor centers during static tasks. (cdc.gov)

This direct measure of neural and hemodynamic activity shows that the insula, one of the most densely connected hubs in the developing cortex, is a major source of the transient bursting events that are critical for brain maturation. (elifesciences.org)

The classification performance revealed no significant differences across subjects, indicating that all three methods are equally well-suited for single-trial movement prediction. (dfki-bremen.de)
On the other hand, we obtained significant differences in the distance measure, favoring wMNE even after correcting the distance with the number of reconstructed clusters. (dfki-bremen.de)
There were also significant differences in EDA measures between baseline and after treatment in the acute BD groups. (medscape.com)

The putative role of the amygdala during mild stress, in modulating the complexity of a coordinated neural network linking brain to heart, is discussed. (nature.com)

Cats are natural hunters, so it's likely that their dreams involve scenarios related to stalking prey, pouncing, or engaging in playful activities. (petguin.de)

The activity occurs in brain areas where emotions, memory and smells are processed. (neurosciencenews.com)
It seems in recent times our attention has turned to using substances, activities and people to regulate our emotions. (mindfood.com)
No differences in asymmetry were found between emotions in the central and parietal regions. (virginia.edu)

For patients with brain tumors or for epilepsy patients who require surgery, MEG can help precisely identify the areas to be removed. (froedtert.com)

Much of what is known about sex differences in the stress-induced activity of the HPA axis and their underlying mechanisms comes from studies done in rodents. (nature.com)
We conclude with a brief discussion of sex differences in the human HPA axis with the caveat that they are less pronounced than in rodents and are largely dependent on the stress modality. (nature.com)

A study led by Stanford researcher Gregory Bratman showed that people who walked for 90 minutes in a natural area, as opposed to participants who walked in a high-traffic urban setting, had decreased activity in a region of the brain associated with a key factor in depression. (mindfood.com)
