Language production in neurological populations

2019-06-01

We use experimental tasks to probe language production processes in neurological populations. This approach can lead to refining theories of production, on the one hand, and to important clinical insights, on the other hand.

Lesion evidence for a critical role of left posterior but not frontal areas in alpha-beta power decreases during context-driven word production
Studies suggest that alpha–beta power decreases index word retrieval in context-driven word production. We recorded the electroencephalogram from patients with stroke lesions encompassing the left lateral-temporal and inferior-parietal regions or left lateral-frontal lobe. Results indicate a critical role for the left posterior, but not frontal cortex, in generating the alpha–beta power decreases underlying context‐driven word production.
