We investigated how degraded speech sounds activate the auditory cortices of the left and right hemisphere. To degrade the stimuli, we introduce uniform scalar quantization, a controlled and replicable manipulation, not used before, in cognitive neuroscience. Three Finnish vowels (/a/, /e/ and /u/) were used as stimuli for 10 participants in magnetoencephalography registrations. Compared with the original vowel sounds, the degraded sounds increased the amplitude of the right-hemispheric N1m… CONTINUE READING
