University of Birmingham researchers report a delayed response to processing written words could signify an increased risk of developing Alzheimer's disease in patients with MCI.
In people with PTSD, the brain expresses an enhanced response to deviant tones, suggesting their brains over process any environmental changes. Additionally, researchers note, the more enhanced the response, the worse those with PTSD performed on cognitive and memory tests.
A new study published in Frontiers in Ecology and Evolution reveals turtle brains have evolved slowly, but constantly, over the last 210 million years. The study also reveals the first turtles with fully formed shells were more likely to have lived on land, not in the water.
Contrary to previous findings, researchers report Omega 3 fatty acids do not help improve reading, learning and memory skills in school aged children.
According to researchers, older adults who exercised for most of their lives showed signs of slowed down aging. The study reports those who actively cycled into older age had lower cholesterol levels and better immune systems than those who did not partake in regular exercise.
Older adults with higher levels of aerobic fitness suffer less often from age related memory failures, researchers report.
Study reports people access fully detailed memories at different speeds and levels of detail, often accessing older information first. Findings could help developing treatments for those with PTSD, researchers say.
A new MRI study reveals those who get to sleep and wake up late have lower resting brain connectivity in regions associated with the maintenance of consciousness. Researchers report the reduced brain connectivity is linked to poorer attention, slower reactions and increased daytime sleepiness.
Maternal exposure to infection prior to pregnancy can transfer into life long cellular immunity in infants who are breastfed.
Memory performance can be enhanced by rhythmic neural stimulation, using both invasive and non-invasive techniques.
