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.

The processing of non-canonically ordered constituents in long distance dependencies by pre-school children: a real-time investigation.

Four experiments were performed which had the goal of determining how and when young children acquire the ability to understand long distance dependencies. These studies examined the operations underlying the auditory processing of non-canonically ordered constituents in object-relative sentences. Children 4-6 years of age and an adult population participated in the study, which employed a cross modal picture priming methodology to determine when constituents in a non-canonical position are reactivated during ongoing sentence comprehension.
