Transcranial direct current stimulation headset receives FCC approval The headset is an early player in the wave of non-invasive devices that will enable improved brain function.  It passes direct current between the cathode and anode, which are placed over the prefrontal cortex, making neurons more excitable.  This helps them to fire more quickly, improving reaction time. When the currents are removed, […]

Motion sensor – potential for autism diagnosis and treatment? Rutgers and Indiana University researchers have developed a motion sensor that they claim can help diagnose and treat autism. A movement tracker is attached to the individual, which senses “systemic signatures,” measuring each person’s movement as they respond to various screen images from a computer program showing 240 images a second.  This analyzes the importance […]

Neuromorphic chip mimics human brain in real time University of Zurich and ETH Zurich scientists have created a two by two millimeter microchip with 11,011 electrodes that mimics the brain’s processing power.   The brain-like microchips are not sentient beings, but can carry out complex sensorimoter tasks in real time.  Previous brain-like computer systems have been slower and larger.  This system, developed by Professor […]

FDA approves EEG-based device to diagnose ADHD US regulators have approved a device that analyzes brain activity to help confirm a diagnosis of attention deficit hyperactivity disorder in children ages 6-17.  It records different kinds of electrical impulses given off by neurons in the brain and the frequency the impulses are given off each second. The EEG based, Neuropsychiatric EEG-Based Assessment Aid test is […]

Computer model of the brain simulates daydreams Washington University researchers have created a computer model to help scientists learn how the brain’s anatomical structure contributes to the creation and maintenance of resting state networks.   They hope that the model will help them understand why certain portions of the brain work together when a person daydreams or is mentally idle, helping doctors better […]

Device uses sounds to build mental images University of Bath scientists have developed the vOICe sensory substitution device to help blind people use sounds to build a mental image of things around them. Blindfolded study participants captured an accurate mental image of an object in front of them when a wearable camera and the vOICe device converted its visual image into […]

Avatar therapy addresses voices in schizophrenia Researchers at University College London and the Wellcome Trust have developed an avatar based system to enable those suffering from schizophrenia to control the voice of hallucinations. The patient creates a computer-based avatar, choosing the face and voice of the entity they believe is talking to them. The system then synchronizes the avatar’s lips […]

High resolution mapping uncovers brain circuit architecture Salk and Gladstone Institute scientists have found a way to untangle neural networks by enhancing a brain mapping technique that they first developed in 2007. “These initial results should be treated as a resource not only for decoding how this network guides the vast array of very distinct brain functions, but also how dysfunctions […]

Eye tracking data helps diagnose autism, ADHD, Parkinson’s USC’s Laurent Itti and researchers from Queen’s University in Ontario have created a data heavy, low cost method of identifying brain disorders through eye tracking.  Subjects watch a video for 15 minutes while their eye movements are recorded. An enormous amount of data is generated as the average person makes three to five saccadic […]
