This program aims at defining the neural architecture involved in information processing within the human brain, and how information (especially that specific to man kind: words, sentences, numbers,…) is encoded at different levels along brain regions. An important goal is to understand how circuits present in non-human primates are reused to engage in new activities, such as written language from visual pattern recognition areas or number manipulation from spatially mapped parietal areas. Correlations with studies in awake primates will thus also be an important part of this program. With knowledge of the brain ‘encoding’ processes it will become possible to ‘read’ mental representations from imaging signals using learning techniques (eg, Support Vector Machines). Another important component is brain dynamics - the temporal features of the brain signals generated by brain function and cognitive processes. Multimodality is then an important requirement, as fast MRI signals collected at UHF must be integrated to those obtained by MEG or EEG. Advanced statistical processing methods are under development to decode temporal information from those signals.
