New link between sleep arousals and body temperature may also be connected to SIDS

What is the origin of these arousals? Scientists have discovered that brief arousals are probably triggered by the intrinsic electrical noise from wake-promoting neurons (WPN) in the brain. Their research reveals a previously unrecognized neurophysiological mechanism that links sleep arousals with temperature regulation, and may also provide an important new link between temperature and Sudden […]

When do problems with memory and decision-making affect older adults' ability to drive?

Recently, a team of researchers designed a study to learn more about cognitive health and older drivers’ crash risks. The study focused on links between levels of cognitive function and crash risk among older drivers without dementia over a 14-year study period. They also assessed the link between changes in cognitive function over time and […]
