Phillip Alvelda: More intelligent; less artificial | ApplySci @ Stanford

Cortical founder and former DARPA NESD program manager Phillip Alvelda discusses AI and the brain at ApplySci’s Wearable Tech + Digital Health + Neurotech Silicon Valley conference on February 26-27, 2018 at Stanford University: Join ApplySci at the 9th Wearable Tech + Digital Health + Neurotech Boston conference – September 25, 2018 at the MIT Media […]

Software records, organizes, analyzes 1 million neurons in real-time

Martin Garwicz and Lund University colleagues have developed a novel method for recording, organizing, and analyzing enormous amounts of neurohysiological data  from  implanted brain computer interfaces. The technology simultaneously acquires data from 1 million neurons in real time. It converts spike data and sends it for processing and storage on conventional systems. Subject feedback is provided in […]

Closed loop EEG/BCI/VR/physical therapy system to control gait, prosthetics

Earlier this year, University of Houston’s Jose Luis Contreras-Vidal developed a closed-loop BCI/EEG/VR/physical therapy system to control gait as part of a stroke/spinal cord injury rehab program.  The goal was to promote and enhance cortical involvement during walking. In a study, 8 subjects walked on a treadmill while watching an avatar and wearing a 64 […]

Direct brain path for sight, sound via implanted microscope

Rice University’s Jacob Robinson, with Yale and Columbia colleagues, are developing FlatScope — a flat, brain implanted microscope that monitors and triggers neurons which are modified to be fluorescent when active. While capturing greater detail than current brain probes, the microscope also goes through deep levels that illustrate  sensory input processing — which they hope to […]

Tetraplegic patient moves arm with thoughts via BCI/FES system

Bolu Ajiboye and Case Western colleagues used an implanted  BrainGate2 brain-computer interface to allow a tetraplegia patient to control arm movements via an implanted FES muscle stimulation system.  A robotic arm, which was needed in previous BrainGate experiments,  was no longer required. Neural activity was recorded from two 96-channel microelectrode arrays implanted in the motor […]

Magnetic coils might improve neural prostheses

Neocortex stimulation is used to treat neurological disorders, including Parkinson’s disease and paralysis. Current electrode-based implants have limited efficacy. It is difficult to create precise patterns of neural activity, or to achieve consistent responses over time.  This can be addressed by magnetic stimulation, but until now, coils small enough to be implanted into the cortex […]
