IS 39. Enhanced visuo-spatial and language learning with tDCS
Efficacy and effectiveness of training in conditions like chronic post-stroke aphasia or neglect, or neurodegenerative disorders like mild cognitive impairment (MCI) and Alzheimer’s disease, remain moderate only. Thus, novel strategies to enhance training success and overall behavioural outcome are urgently needed. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation tool that is now being widely used in neuroscientific and clinical research in humans, modulating cortical excitability by application of weak electrical currents in the form of direct current brain polarization.In a series of st...

IS 12. Plasticity in stroke patients: Why brain stimulation may (not) work
Advances in brain imaging techniques allow us to study not just what the brain looks like but how it works. When applied to people who have suffered a stroke this technology has demonstrated reorganization of the way surviving brain regions function. These findings give hope to the idea that new treatments can be designed and more effectively targeted towards individual patients.So how can we measure these changes in organization in the human brain? Brain imaging techniques such as functional magnetic resonance imaging (fMRI) have developed to the point where a detailed appreciation of the damage to brain structures and th...

S14-4. Possibility of a useful intervention of exercise induced by muscle fatigue to change excitabilities of corticospinal and cortico-cortical tracts for functional recovery in neurorehabilitation
Motor learning and synaptic plasticity in the cortex are enhanced by interventions that reduce the effectiveness of GABAergic intracortical inhibition. The disinhibition of SICI by muscle fatigue could enhance synaptic plasticity and improve the consolidation of motor learning. We found that the corticospinal excitability and SICI decrease after exhaustive muscle contraction or muscle fatigue. It seems possible that decreased SICI can enhance synaptic plasticity if motor learning or skill training is combined with muscle fatigue. Interestingly, fatigue in muscles on the opposite side of the body or in lower limb muscles re...

Toward a better dexterity: Direction for future studies
Performing an accurate and adequate motor task is a key function in our daily living activities, and improvement of dexterity is a main concern especially in stroke survivors. Thus, the development of new strategies to improve motor learning and to promote stroke recovery is desirable.
