The studies presented here use an adapted oddball paradigm to show evidence that representations of discrete phonological categories are available to the human auditory cortex. Brain activity was recorded using a 37-channel biomagnetometer while eight subjects listened passively to synthetic speech sounds. In the phonological condition, which contrasted stimuli from an acoustic /d/-/t/ continuum, a magnetic mismatch field (MMF) was elicited in a sequence of stimuli in which phonological… CONTINUE READING
