S3-3. Clinical application of electroencephalogram-based brain-machine interfaces
A large number of electroencephalogram-based brain-machine interface (BMI) systems developed by industry and academia are now available for neurorehabilitation. However, the lack of phase 1 –2 clinical trials for BMI interventions to post-stroke hemiplegia has been limited their treatment outcome. To test the safety and feasibility of BMI interventions, we conducted trials with a customly developed BMI system for patients with acute/subacute hemiparetic stroke. Four inpatients partic ipated in this study in the early phase (7–24 days from stroke onset).

A cloudy story: Guillain–Barré syndrome concealed by a spontaneous intracerebral haemorrhage
We present a case of Guillain–Barré syndrome (GBS), probably associated with influenza vaccine, occurring in a patient some days after a spontaneous haemorrhagic stroke. A 79-year-old woman was admitted to the neurosurgery department after a sudden severe headache, dizziness, and progressive generalised weakness. She had a history of hypertension and paroxysmal atrial fibrillation in dicumarolic therapy. Head CT scan showed a haemorrhagic stroke in left cerebellum, with compression on the fourth ventricle.

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.

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...

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...

P 84. High-frequency neuronavigated cerebellar repetitive Transcranial Magnetic stimulation (rTMS) increases human pharyngeal motor cortex excitability
Conclusions: Our data show for the first time that high-frequency (10Hz) cerebellar stimulation can produce long-lasting increases in human pharyngeal motor cortex excitability, with larger and longer-lasting effects of the intervention primarily seen in the contralateral projection. Hence 10Hz cerebellar rTMS may play a therapeutic role in the treatment of dysphagia after hemispheric stroke.

P 126. Righthemispheric inhibitory rTMS in patients with letfsided brain infarcts: Effect on cerebral blood flow using PET and speech performance
Discussion: rTMS with inhibitory effect on the rightsided homologous speech area plus speech therapy in patients with left sided brain infarcts and aphasia results in better recovery of language performance compared to patients who received speech therapy only.

P 229. Transcranial Laser Stimulation-A New Method for Non-Invasive Modulation of Cortical Excitability
Conclusions: The M1 excitability was found to be reduced after TLS in dose dependent manner. These findings may give insight into the mechanisms of nirLLL effects in the human cerebral cortex, also suggesting more suitable applications of TLS in clinical settings.

11. “Two is better than one”? Simultaneous monitoring of multichannel somatosensory evoked potentials and electroencephalogram during carotid endarterectomy
In carotid endarterectomy (CEA), EEG and somatosensory evoked potentials (SEPs) are the most commonly used monitoring techniques to prevent perioperative stroke. However, which of these methods is the most appropriate is not definitely established. Here we evaluated retrospectively simultaneous EEG and SEP recordings. Our CEA series was analyzed backward to identify 30 patients requiring carotid shunt. Shunting was performed in 7.1% of 420 consecutive CEA over a 20-month period. All CEAs were continuously monitored by multi-channel EEG and SEPs before, during and 20min following carotid cross-clamping. The most reliable SE...

Reply to “Perception of lower extremity loading in stroke”
As reflected by the comments of Kumar et al. (2014), there is an increasing interest in developing quantitative measurements of complex sensorimotor behaviors in people with neurologic injury or disease. In concept, our manuscript “Perception of lower extremity loads in stroke survivors” addresses one of these behaviors, which is likely to be important to gait function in stroke survivors. While we believe that impairment in load perception plays an important role in gait, Kumar et al. raise many important issues related to interpreting data from testing paradigms with higher complexity, and in extrapolating these labo...

The P300 in middle cerebral artery strokes or hemorrhages: outcome predictions and source localisation
Stroke is the leading cause of disability and is the third leading cause of death worldwide (Murray and Lopez, 1997). According to the World Health Organisation, a total of 15 million people suffer a stroke each year. Strokes can principally be classified into two main categories, ischemic and hemorrhagic (Donnan et al., 2008). 85 % of all strokes are of ischemic origin (Qureshi et al., 2001) and most commonly occur within the territory of the middle cerebral artery (MCA). The MCA supplies the lateral portion of the cerebral cortex (about 60 % - 70 % of the hemisphere).
