A team led by Carola Wiklund-Hörnqvist at Umeå University, tracked brain activity in humans while being repeatedly tested with or without feedback.
The technology behind the game, which Neurable showed me and also demonstrated at the Siggraph conference on computer animation and interactive techniques in Los Angeles last week, uses dry electrodes placed on the scalp and electroencephalography to track brain activity.
It tracks brain activity using a single electroencephalography sensor (EEG) at the forehead, as well as other sensors that monitor breathing rate, head motion, heart rate, blink rate, and skin temperature.
The company has developed a sensor-laden headset that tracks brain activity using a single electroencephalography sensor (EEG) at the forehead, and other sensors that monitor breathing rate, head motion, heart rate, blink rate, and skin temperature all of which can be indicators of whether a person is engaged or excited.
Studying food choice is a really nice pathway to find the brain mechanisms of restrictive eating". Steinglass and psychology professor Daphna Shohamy, a principal investigator at the Zuckerman Mind Brain Behavior Institute, tracked brain activity in anorexic patients in a recent study.
Using Bluetooth technology, the headband tracks brain activity and gives real-time feedback via guiding sounds.
fMRI is normally used to track brain activity by measuring blood flow.
Another example used a television comedy as the stimulus, and tracked brain activity over time as the assay of online processing (Hasson, Furman, Clark, Dudai, & Davachi, 2008).
Studying this neural wiring in humans is difficult because the only technique available to track brain activity in real time, called functional magnetic resonance imaging (fMRI), does not yet have the resolution to watch individual neurons at work.
