Fujitsu, GE Healthcare, Macquarie University and Macquarie Medical Imaging are using AI to detect and monitor brain aneurysms on scans faster and more efficiently. Fujitsu will use AI to analyze brain images generated by GE’s Revolution C scanner and an algorithm that detect abnormalities and aneurysms. The algorithm will be capable of highlighting an arterial ring […]
Building on his prior brain-controlled prosthetic work, Stanford’s Krishna Shenoy has developed a simpler way to study brain electrical activity, which he believes will lead to tiny, low-power, wireless brain sensors that would bring thought-controlled prosthetics into much wider use. The method involved decoding neural activity in aggregate, instead of “spike sorting.” Spike sorting must be […]
Clive Svendsen, Gad Vatine, and Cedars Sinai and Ben Gurion University of the Negev colleagues have recreated the blood-brain barrier outside of the body using induced pluripotent stem cells for the first time. In a study, the recreated bbb functioned as it would in the individual who provided the cells to make it. This could […]
Adam Gazzaley and UCSF colleagues have developed a focus-driven digital meditation program that improved attention and memory in healthy adults in a recent study. MediTrain tailors meditation session length to participant abilities, and challenges users to increase session time. Subjects received significant benefits in 6 weeks. On their first day, they focused on their breath […]
Miguel Nicolelis has developed a non-invasive system for lower-limb neurorehabilitation. Study subjects wore an EEG headset to record brain activity and detect movement intention. Eight electrodes were attached to each leg, stimulating muscles involved in walking. After training, patients used their own brain activity to send electric impulses to their leg muscles, imposing a physiological gait. With […]
University of Vermont researchers have developed an algorithm that detects anxiety and depression in children’s voices with 80 per cent accuracy, according to a recent study. Standard diagnosis involves a 60-90 minute semi-structured interview with a trained clinician and their primary care-giver. AI can make diagnosis faster and more reliable. The researchers used an adapted […]
Klaus Gerwert at Ruhr-Universität Bochum has developed a blood + CSF test that he claims can detect Alzheimer’s disease 8 years before the onset of symptoms. The goal is early stage therapy to achieve better results than current treatment protocols. To reduce false positive results from the initial study, the researchers first used a blood […]
Edward Chang and UCSF colleagues are developing technology that will translate signals from the brain into synthetic speech. The research team believes that the sounds would be nearly as sharp and normal as a real person’s voice. Sounds made by the human lips, jaw, tongue and larynx would be simulated. The goal is a communication method for […]
Charles Marmar, Adam Brown, and NYU colleagues are using AI-based voice analysis to detect PTSD with 89 per cent accuracy, according to a recent study. PTSD is typically determined by bias-prone clinical interviews or self-reports. The team recorded standard diagnostic interviews of 53 Iraq and Afghanistan veterans with military-service-related PTSD, as well as 78 veterans without […]
NeuroSigma has received FDA clearance for its forehead patch which stimulates the trigeminal nerve during sleep to treat ADHD. The device won CE Mark approval in Europe in 2015. The approval was based on study of 62 subjects. Over four weeks, those who received the treatment showed a decrease in ADHD-RS by -31.4%. The control group showed a -18.4% decrease. […]
