New ‘4D goggles’ allow wearers to be ’touched‘
Posted by Saúl Morales Rodriguéz in categories: entertainment, media & arts, neuroscience, space travel, virtual reality
A team of researchers at UC San Diego and San Diego State University has developed a pair of “4D goggles” that allows wearers to be physically “touched” by a movie when they see a looming object on the screen, such as an approaching spacecraft.
The device was developed based on a study conducted by the neuroscientists to map brain areas that integrate the sight and touch of a looming object and aid in their understanding of the perceptual and neural mechanisms of multisensory integration.
But for the rest of us, the researchers said, it has a more practical purpose: The device can be synchronized with entertainment content, such as movies, music, games and virtual reality, to deliver immersive multisensory effects near the face and enhance the sense of presence.

Failure of the Blood-Brain Barrier Proceeds Dementia
Posted by Steve Hill in categories: biotech/medical, neuroscience
New research from the University of Southern California has shed light on how the decline of the brain’s vascular system precedes the build-up of the plaques and tau tangles associated with Alzheimer’s disease.
A leaky blood-brain barrier sets the scene for dementia
Traditionally, many researchers have focused their efforts on the amyloid and tau proteins that accumulate in the brain and are typical of Alzheimer’s disease progression. However, the researchers in this new study suggest that the problem begins before this due to a leaking blood-brain barrier [1].

A Potential Blood Test for Alzheimer’s Disease
Posted by Steve Hill in categories: biotech/medical, neuroscience
A simple technique to measure the amount of amyloid beta in the brain could improve diagnosis and drug trials for Alzheimer’s disease, according to the results of new research.
A simple blood test
Japanese researchers led by Dr. Katsuhiko Yanagisawa have published a new study suggesting that a screening test could help to boost the success rate of Alzheimer’s drug research. The research team has shown that a simple blood test can accurately measure the amount of amyloid beta, a protein that appears in the early stages of Alzheimer’s disease.

Tickling the brain with electrical stimulation improves memory, study shows
Posted by Shailesh Prasad in categories: biotech/medical, neuroscience
Tickling the brain with low-intensity electrical stimulation in a specific area can improve verbal short-term memory. Mayo Clinic researchers report their findings in Brain.
The researchers found word recall was enhanced with stimulation of the brain’s lateral temporal cortex, the regions on the sides of the head by the temples and ears. Patients recalled more words from a previously viewed list when low-amplitude electrical stimulation was delivered to the brain. One patient reported that it was easier to picture the words in his mind for remembering.
“The most exciting finding of this research is that our memory for language information can be improved by directly stimulating this underexplored brain area,” says Michal Kucewicz, Ph.D., a Mayo Clinic researcher in the Department of Neurology and co-first author. Dr. Kucewicz compares the stimulation to “tickling” the brain.
