DECODING MENTAL STATES FROM HUMAN BRAIN ACTIVITY
Is it possible to predict what a person is thinking based alone on their current brain activity? This project investigates ways to decode and predict a person’s thoughts based from functional magnetic resonance imaging (fMRI) data. Such “thought reading” can reveal how information is neurally encoded in the brain. The idea is that it is only possible to decode a thought if one knows the correct code. Such research has many potential application, as for example in detection of deception, in the control of computers and artificial prostheses by brain activity, or even (more controversial) in market research.
ATTENTION, AWARENESS AND FUNCTIONAL BRAIN CONNECTIVITY
This project investigates the relationship between consciousness, attention and dynamic changes in brain connectivity. We have so far demonstrated an increased connectivity between early and late visual areas when subjects become aware of stimuli. Changes in spatial attention lead to highly specific changes in connectivity within early visual areas. Wenn subjects were asked to compare two stimuli presented in their visual field the connectivity between their retinotopic representations was was increased. Such studies of connectivity reveal how remote brain areas cooperate in mediating awareness and attention.
