Movement velocity effect on cortical reorganization and finger function in stroke.
… of function is linked to favorable brain reorganization. The brain is primed for neuroplastic reorganization after stroke but the rehabilitation interventions must be well designed. Forced use of the paretic limb as a training regimen has been shown to be effective; however, the optimal …

A Rodent Animal Model for Forelimb to Lower Jaw Reorganization in Primary Somatosensory Cortex (SI) Barrel Field
… this study is to examine mechanisms underlying cortical reorganization in rat primary somatosensory (SI) cortex that follows forelimb deafferentation. The majority of human patients suffering from limb loss or brachial plexus avulsion injury, as well as patients that receive brachial plexus …

Some principles of somatosensory cortical organization in rats and humans
… research elucidated principles of somatosensory cortical al organization at the level of the receptive field, cortical map, and cortical area in the rat and human. throughout these studies, a central focus was on the connection between each level of organization and the capacity for cortical …

Dynamic and Integrative Properties of the Primary Visual Cortex
… as the association field (AF). We first used cortical reorganization as a model to investigate the role that a specific network of V1 connections, the long-range horizontal connections, might play in temporal and spatial integration across the AF. When retinal lesions ablate sensory …

Sound-to-Touch Sensory Substitution and Beyond
… (2) the brain has the remarkable capability of cortical reorganization. Sensory substitution has previously been successfully applied as a solution for blindess via vision-to-touch substitutions. To this end, a sound-to-touch sensory substitution device, The Versatile Extra-Sensory Transducer …

Brain Activation and Connectivity In Non-Disabled Multiple Sclerosis Patients
… patients with MS. Recent evidence has implicated cortical reorganization as a mechanism to limit the clinical manifestation of the disease. Functional MRI was used to test the hypothesis that non-disabled MS patients (Expanded Disability Status Scale ≤ 1.5) show increased recruitment of cognitive …

Circuit Dynamics of Adult Visual Cortex
… plasticity in the adult V1, we studied the cortical reorganization that accompanies retinal lesions. Removal of visual input cause axonal sprouting of long-range horizontal connections from pyramidal cells in layer 2/3. Our in vivo approach allowed us to determine the dynamics of the process …

Localization and Function Of RNA Interference in the Cerebral Cortex
<p>During the course of adult cortical plasticity, a number of signal transduction mechanisms are brought into play. To study regulatory genes implicated in this process, we inhibited gene expression by harnessing the machinery of RNA interference (RNAi) pathway via small hairpin RNAs (shRNA) …

Neuropsychological functions and association with single photon emission computed tomography (SPECT) in Greek multiple sclerosis patients : efficacy of a computerized cognitive rehabilitation intervention
… plasticity mechanisms might be hampered and cortical reorganization of the brain is limited, restorative or functional cognitive training interventions utilizing either computer assisted or manualized interventions have demonstrated positive pre to post treatment effects, including good …
