Left anterior temporal cortex actively engages in speech perception: A direct cortical stimulation study

▸ Importance of anterior temporal cortex in speech comprehension implicated in semantic dementia. ▸ Direct cortical stimulation of anterior STS/STG impaired auditory sentence comprehension with preserved visual sentence comprehension. ▸ Sentences heard as a series of meaningless utterance. ▸ Sites of stimulation well corresponded with those of speech perception in fMRI activation studies.
