Neuroimaging of multimodal sensory stimulation in amyotrophic lateral sclerosis

Abstract

Multiparametric MRI suggests a progressive functional deficit in secondary/higher order sensory processing areas in ALS, probably associated with reduction of re-afferent information flow due to progressive immobility. The changes described might also represent an expression of the disease process itself. Evidence for compensatory processes in multimodal associative cortices was found.
