ABSTRACT Diana Miglioretti, PhD Candidate in Biostatistics This talk will describe a statistical approach for the analysis of
direct
cortical electrical interference (DCEI) data with the goal of delineating
and comparing cortical regions critical for two language tasks: adult
speech discrimination and auditory comprehension. It is hypothesized that
speech discrimination is more localized and auditory comprehension more
dispersed both within and between individuals.
DCEI is performed with surgically implanted, indwelling, subdural
electrode arrays, often covering the lateral left cortical surface. A
current passed between a pair of adjacent electrodes creates a temporary
lesion during testing, producing a spatial array of binary responses for
each patient.
