Technology.am (Sept. 09, 2009) — University of Victoria researcher Phil Zeman has developed a new and less expensive procedure for analyzing electroencephalogram (EEG) data that identifies the location of special brain activities.
Traditionally, it is functional Magnetic Resonance Imaging (fMRI) that is used to identify which areas of the brain are active during different mental states.
Zeman’s technology is an inexpensive alternative to fMRI—$100,000 versus several million dollars. It also requires little maintenance and can be used in an ordinary laboratory or office.
The EEG analysis tool is called “Multiple Origin Spatio-Temporal modeling of EEG” (MOST-EEG).
The University of Victoria invention uses the electrical activity obtained from a person’s scalp, recorded while she or he plays a video game. The tool provides a 3-D representation of brain activity during different mental states.
The procedure could be used to identify areas of the brain that aren’t working properly or aren’t communicating well to other areas.
It also has the potential to track brain changes underlying the kind of neuroplasticity—the capacity of the nervous system to modify its organization—that may be a factor in recovery from stroke and brain injury.
