Localisation of Brain Functions: Stimuling Brain Activity and Source Reconstruction for Classification (2006)
Abstract / truncated to 115 words
A key issue in understanding how the brain functions is the ability to correlate functional information with anatomical localisation. Functional information can be provided by a variety of techniques like positron emission tomography (PET), functional MRI (fMRI), electroencephalography (EEG), magnetoencephalography (MEG) or transcranial magnetic stimulation (TMS). All these methods provide different, but complementary, information about the functional areas of the brain. PET and fMRI provide spatially accurate picture of brain regions involved in a given task. TMS permits to infer the contribution of the stimulated brain area to the task under investigation. EEG and MEG, which reflects brain activity directly, have temporal accuracy of the order of a millisecond. TMS, EEG and MEG are offset ... toggle 7 keywordsbrain-computer interface – BCI – brain-machine interface – BMI – EEG – inverse solution – TMS
