TL;DR: Description of mapping methods using spherical splines, both to interpolate scalp potentials (SPs) and to approximate scalp current densities (SCDs) with greater accuracy in areas with few electrodes.

TL;DR: The present data corroborated the functional neuro-anatomy of word recognition systems suggested by other neuroimaging methods and described their timecourse, supporting a cascade-type process that involves different but interconnected neural modules, each responsible for a different level of processing word-related information.

TL;DR: Surface splines are mathematical tools for interpolating functions of two variables that are smoother, give more precisely located extrema and converge faster toward the 'true' potential surface when the number of recording electrodes is increased.

TL;DR: The dissociation of an exogenous, obligatory frontal component from the sensory-specific response in the auditory N1 suggests that parallel processes served by distinct neural systems are activated during acoustic stimulation.

TL;DR: This study demonstrates that simple dipolar models, applied on electrical data, make it possible to reveal functionally distinct cortical areas in the auditory cortical area involved in the N100 wave generation.
