Defining Hypoperfusion in Chronic Aphasia: An Individualized Thresholding Approach.

Within the aphasia literature, it is common to link location of lesioned brain tissue to specific patterns of language impairment. This has provided valuable insight into the relationship between brain structure and function, but it does not capture important underlying alterations in function of regions that remain structurally intact. Research has demonstrated that in the chronic stage of aphasia, variable patterns of reduced cerebral blood flow (CBF; hypoperfusion) in structurally intact regions of the brain contribute to persisting language impairments.

Cross-modal phonetic encoding facilitates the McGurk illusion and phonemic restoration.

In spoken language, audiovisual (AV) perception occurs when the visual modality influences encoding of acoustic features (e.g., phonetic representations) at the auditory cortex.
