(June 28, 2012) Researchers have long been interested in
discovering the ways that human brains represent thoughts through a complex
interplay of electrical signals. Recent
improvements in brain recording and statistical methods have given researchers
unprecedented insight into the physical processes underlying thoughts. For example, researchers have begun to show
that it is possible to use brain recordings to reconstruct aspects of an image
or movie clip someone is viewing, a sound someone is hearing or even the text
someone is reading.
