Inside the extraordinary nose of a search-and-rescue dog

The blizzard arrived in Alpine Meadows without warning. Hours earlier, before a half moon rose over this California resort town near Lake Tahoe, an uncle and his teenage nephew had been separated from their hunting party. Authorities called veteran rescue dog handler Shay Cook, who rushed to the mountain site with her dog Rixi, never […]

ELECTRONIC ‘NEURAL DUST’ COULD MONITOR YOUR BRAIN

Wireless sensors that can be implanted in a person’s body to control robotic devices have been developed by researchers hoping to transform brain-to-computer interfaces. Scientists at the University of Berkeley, California, built the so-called “neural dust” device and tested its functionality in the muscles and peripheral nerves of rats. “I think the long-term prospects for […]

Engineers implanted tiny sensors in rats’ nerves and muscles. Are humans next?

Sensors the size of a grain of sand could one day explain what’s happening in your body from the inside out. Engineers at the University of California, Berkeley, implanted wireless sensors measuring just one millimeter cubed  in the muscles and nerves of lab rats, then used ultrasound waves to extract information from them about how well […]

Beyond Fitbit: ‘Neural dust’ puts invisible cyborg tech deep inside you

New, tiny sensors could create superpowerful fitness trackers, move prosthetics forward and lead to treatments for conditions like epilepsy. Monitoring your heart rate and VO2 max (maximum oxygen volume) with the latest fitness tracker is nifty, but researchers are developing new, tiny tech to keep track of just about any organ, nerve or muscle in […]

Wireless ‘Neural Dust’ Could Monitor Your Brain

SAND-SIZED SENSOR IMPLANTS GIVE INSTANT FEEDBACK FROM NERVE CELLS Science fiction that features wires connecting brains to computers might now be obsolete. Wireless powered implants, each smaller than a grain of rice, could serve as “neural dust” that can one day scan and stimulate brain cells. Such research could one day help lead to next-generation […]

Sprinkling of neural dust opens door to electroceuticals

University of California, Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time. Because these batteryless sensors could also be used to stimulate nerves and muscles, the technology also opens the […]

Elders use brain networks differently for short-term recall

Older people’s short-term memory is generally slower and less accurate compared to younger people. But a new University of California, Berkeley, study suggests that brains that continue to perform well in old age do so by rallying more of the brain to complete mental tasks. The researchers suggest that the age-associated changes observed in network […]

Mental, Physical Exercises Produce Distinct Brain Benefits

Cognitive brain training improves executive function whereas aerobic activity improves memory, according to new Center for BrainHealth research at The University of Texas at Dallas. The study, published in Frontiers in Human Neuroscience, found that healthy adults who participated in cognitive training demonstrated positive changes in executive brain function as well as a 7.9 percent increase […]

Visual experience tunes detection of motion direction in the retina

Labelled Ganglion Cells Layer

The retina contains an important class of neurons called Direction Selective Ganglion Cells (DSGCs) that enable animals to determine the direction an object is moving across its visual field. Mature DSGCs respond strongly to objects moving in one of several preferred directions that lie along cardinal axes – up, down, left, or right. In their […]
