Título: Prospects for high-resolution imaging of scalp EEG and mobile brain/body imaging
Resumen: Though the electroencephalogram (EEG) was the first brain activity imaging modality (1926-), ironically it remains the least technically developed – despite its clear advantages for low cost, non-invasive human brain imaging that enable its use in large or very large research, screening, and diagnostic applications. Its technical disadvantage arises from the spatial mixing of potentials originating in brain cortex as they pass through brain tissue conductance boundaries. I will present evidence that high-resolution EEG source imaging is possible. Further, another strength of EEG imaging – its lightweight sensors – allows EEG to play a central role in new mobile brain/body imaging (MoBI) systems to study brain dynamics supporting our natural cognition – our normal actions and experience, including social interactions, in normal 3-D environments.
