Summary: A new speech prosthetic offers hope for those with speech-impairing neurological disorders. By converting brain signals into speech using high-density sensors and machine learning, the technology represents a significant advancement over current slower communication aids. Though still in early stages, the device has achieved a 40% accuracy in decoding spoken data during limited trials...

Researchers record brainwaves to measure ‘cybersickness’
by Maria Herd, University of Maryland A test subject experiences a potentially stomach-churning virtual reality fly-through of a space station while her brain activity is monitored. Credit: Maryland Blended Reality Center If a virtual world has ever left you feeling nauseous or disorientated, you’re familiar with cybersickness, and you’re hardly alone. The intensity of virtual reality...

FOR EACH COVID-19 DEATH, 9 FAMILY MEMBERS GRIEVE
Every death from COVID-19 will affect approximately nine surviving family members, according to a new study of kinship networks in the United States. Deaths from COVID-19 will have a ripple effect causing impacts on the mental health and health of surviving family members. But the extent of that impact has been hard to assess until...

The science of the penny dropping: Scientists discover memory recall and formation happens at specific times ‘due to the oscillation of brainwaves’
By JOE PINKSTONE FOR MAILONLINE Memory formation and recall is linked to specific brainwaves called theta waves These fire three times a second and only when a person learns successfully They originate from the hippocampus region, deep inside a person’s brain They are again produced when a person remembers one of their memories Recall is...

Brainwave activity reveals potential biomarker for autism in children
Kanazawa, Japan – Autism spectrum disorder (ASD) is a neurodevelopmental disorder that can impair communication ability, socialization, and verbal and motor skills. It generally starts in early childhood and is diagnosed through behavior observation. This means of assessment can be imprecise, which is especially problematic when early identification is vital for developmental follow up. A...

Memory ‘brainwaves’ look the same in sleep and wakefulness
Identical brain mechanisms are responsible for triggering a memory in both sleep and wakefulness, new research at the University of Birmingham has shown. Credit: CC0 Public Domain The study sheds new light on the processes used by the brain to ‘reactivate’ memories during sleep, consolidating them so they can be retrieved later. Although the importance...

Microscopic, Remotely Powered Implant to Read, Transmit Brainwaves from Inside Skull
Brain-computer interfaces and other technologies that rely on reading and stimulating the brain require electrodes to obtain and deliver signals, as well as a way to transmit those signals from within the brain. Electric wires have usually served as the method of connectivity, but they create serious challenges, including a potential for infection, safety issues,...

Controlling robots with brainwaves and hand gestures
System enables people to correct robot mistakes on multi-choice problems MASSACHUSETTS INSTITUTE OF TECHNOLOGY, CSAIL Getting robots to do things isn’t easy: usually, scientists have to either explicitly program them or get them to understand how humans communicate via language.
