4D technique promises new insights into brain function

January 23, 2009 It’s kind of ironic that the very organ that gives us our intelligence and understanding of the world around us is also the one we understand the least. Now a novel 4D colorimetric technique developed by researchers at Florida Atlantic University, (FAU), that simultaneously maps four dimensions of brain data, (magnitude, 2D of cortical surface and time), in EEG signals could dramatically change the way neuroscientists are able to understand how the brain operates. The technique makes it possible to observe and interpret oscillatory activity of the entire brain as it evolves in time, millisecond by millisecond, so that for the first time, true episodes of brain coordination can be spotted directly in EEG records and carefully analyzed.
