Phone-based support for psychosis

University of Washington’s Dror Ben Zeev has published a paper detailing a wide array of phone-based technology meant to support the recovery of psychosis throughout life — from early detection to symptom management to vocational rehabilitation, The study includes self reported mental health assessments, self-management interventions, medication reminders, messages from case managers, tele-therapy, and skill […]

Sensor tracks cerebral aneurysm hemodynamics

Georgia Tech’s Woon-Hong Yeo has developed a 3D-printed, stretchable, battery-free, wireless sensor, implanted in brain blood vessels to measure incoming blood flow, to evaluate aneurysm healing.  The tiny device wraps around stents or diverters implanted to control blood flow in affected vessels. It is believed to be the first demonstration of aerosol jet 3D printing to […]

AI detects brain aneurysms, predicts rupture risk in surgery

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 […]

New electrodes, brain signal analysis, for smaller, lower power, wireless BCI

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 […]

App optimizes meditation length to improve attention and memory

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 […]

Study: Noninvasive BCI improves function in paraplegia

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 […]

AI detects depression in children’s voices

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 […]

Thought generated speech

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 […]
