Study reveals how reward enhances connectivity between the ventral striatum and the default mode network, impacting behavior.
Age and gender both appear to affect the relationship between state fatigue and brain activation.
Study reveals an association between signal detection theory, brain activation patterns, and subjective state fatigue. In those with multiple sclerosis, greater effects of fatigue were seen.
Walking exercise on a treadmill improves cognitive abilities, including learning and memory, and preserves hippocampal volume in people with relapse-remitting multiple sclerosis.
Exoskeletons that help those with spinal cord injuries to walk may help to improve bowel function.
Two key metrics of signal detection theory, perceptual certainty and response bias, correlate with changes in cognitive fatigue.
Changes in functional connectivity within the fatigue network occur in response to cognitive fatigue.
People with spinal cord injuries have the same brain activity during processing speed tasks as healthy older adults. The findings suggest the theory of accelerated cognitive aging following SCI is correct.
Those with MS allocate neural resources less effectively when faced with increased cognitive task demands, and this likely results in the increased mental fatigue those with the neurodegenerative disorder experience.
Using a modified story memory technique, people with multiple sclerosis showed improvements in learning and memory. Additionally, fMRI neuroimaging revealed changes in brain activity related to working memory and word encoding.
