Some Neurological Principles Relevant to the Origins of — and the Cortical Plasticity-Based Remediation of — Developmental Language Impairments

Conference paper
Part of the Research and Perspectives in Neurosciences book series (NEUROSCIENCE)


Recent advances in integrative neuroscience have led to an increasing understanding of the brain plasticity mechanisms underlying perceptual, cognitive and motor skill learning in children and in adults (see Merzenich et al. 1991 a, b; Merzenich and Sameshima 1993; Merzenich and DeCharms 1996; Buonomano and Merzenich 1998, for reviews). These studies have shown how these natural neurological processes can contribute to the often-powerful behavioral expressions of chronic neurological illnesses and disabilities (see Merzenich et al. 1991 a, 1993, 1996 a, b; Merzenich and Jenkins 1995; other chapters, this volume). They also point to practical strategies by which the same dynamic brain processes can be marshalled for neuroscience-guided, training-based amelioration of specific neurological impairments.
