Low vitamin D associated with faster decline in cognitive function

A research team has found that Vitamin D insufficiency was associated with faster decline in cognitive functions among a group of ethnically diverse older adults, according to an open-access paper published in JAMA Neurology.* According to the researchers — Joshua W. Miller, Ph.D., of Rutgers University, New Brunswick, N.J., and coauthors from the University of California, Davis — Vitamin D may influence […]

How to increase brain activity and memory

A new international study led by the Research Institute of the McGill University Health Centre (RI-MUHC) suggests it may be. Their research has identified a molecule that improves brain function and memory recall is improved. Published in the latest issue of Cell Reports, the study has implications for neurodevelopmental and neurodegenerative diseases, such as autism spectrum disorders […]

Data-mining our dreams

Using computer analysis to decode the meaning of dreams The Dream, 1910 (credit: Henri Rousseau/Museum of Modern Art) Many people assume that this quest to interpret dreams has failed. This conclusion is premature, Kelly Bulkeley, former president of the International Association for the Study of Dreams and author of Dreaming in the World’s Religions: A Comparative History,” writes […]

How the brain ‘takes out the trash’ while we sleep

Image shows cerebral spinal fluid (in blue) entering the brain via a “plumbing system” that piggybacks on the brain’s blood vessels (credit: URMC) A new study shows that a recently discovered system that flushes waste from the brain is primarily active during sleep, giving fresh meaning to the old adage that a good night’s sleep clears the […]

Restoring touch for amputees using a touch-sensitive prosthetic hand

New research at the University of Chicago is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain (credit: PNAS) New research at the University of Chicago is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via […]

Chips that mimic the brain in real time

Photograph and layout of a multi-neuron chip comprising an array of analog/digital silicon neurons and synapse circuits, that can reproduce biophysically realistic neural response properties and dynamics in real-time. The chip was produced using a standard 0.35μm CMOS technology and it occupies an area of 10 square mm. It has 128 neuron circuits and 5120 […]
