The percept of time relates to the sense of touch. A new SISSA study A sensory integration account for time perception published in
PLOS Computational Biology uncovers this connection. The challenge to neuroscience posed by the sense of time lies, first and foremost, in the fact there do not exist dedicated receptors - the passage of time is a sensory experience constructed without sensors, notes Mathew Diamond, director of the Tactile Perception and Learning Lab. One might imagine a precise clock in the brain, a sort of stopwatch that registers the start and stop and computes the elapsed time between those two instants. But decades of research have not found any brain mechanism resembling a stopwatch. We thought that understanding sensory systems might be the key to understanding sense of time.

BOSTON - How often a person takes daytime naps, if at all, is partly regulated by their genes, according to new research led by investigators at Massachusetts General Hospital (MGH) and published in
Nature Communications. In this study, the largest of its kind ever conducted, the MGH team collaborated with colleagues at the University of Murcia in Spain and several other institutions to identify dozens of gene regions that govern the tendency to take naps during the day. They also uncovered preliminary evidence linking napping habits to cardiometabolic health. Napping is somewhat controversial, says Hassan Saeed Dashti, PhD, RD, of the MGH Center for Genomic Medicine, co-lead author of the report with Iyas Daghlas, a medical student at Harvard Medical School (HMS). Dashti notes that some countries where daytime naps have long been part of the culture (such as Spain) now discourage the habit. Meanwhile, some companies in the United States now promote napping as a way to

Patients with multiple sclerosis who rely on family members as caregivers may be at particular risk for mistreatment, as those caregivers struggle to balance work, childcare, and health concerns of their own.<em> </em><br />
