چکیده
Stroke is one of leading cause of death and disability worldwide. Early detection during golden hour and treatment of individual neurological dysfunction in stroke using easy-to-access biomarkers based on a simple-to-use, cost-effective, clinically-valid screening tool can bring a paradigm shift in healthcare, both urban and rural. In our research we have designed a quantitative automatic home-based oculomotor assessment tool that can play an important complementary role in prognosis of neurological disorders like stroke for the neurologist. Once the patient has been screened for stroke, the next step is to design proper rehabilitation platform to alleviate the disability. In addition to the screening platform, in our research, we work in designing virtual reality based rehabilitation exercise platform that has the potential to deliver visual stimulation and in turn contribute to improving one's performance.

THE EFFECT OF POSTERIOR CEREBRAL PULMONARY DIRECT ELECTRICAL STIMULATION (TDCS) ON IMPROVING SPATIAL, VISUAL, AND VERBAL PERCEPTUAL ABILITIES
Background & Aims: Direct electrical stimulation of the brain is a therapeutic technique that can be effective in improving visual, verbal, and spatial perception. The present study investigated the effect of direct electrical stimulation (tDCS) of the posterior parietal cortex on improving spatial, visual, and verbal perceptual abilities. Materials & Methods: In this quasi-experimental study,...
متن کاملInfluence of Repetitive Light Stimulation on Alpha Dynamics
A relative high power in the alpha band (8 – 13Hz) at a particular EEG position is believed to indicate an active inhibitory state of the corresponding cortical site. According to this hypothesis an active inhibitory state corresponds to a lower engagement of the cortical site and is accompanied by a higher engagement of other sites (possibly neighboring ones). In this project the influence of ...

متن کاملDissociation of response variability from firing rate effects in frontal eye field neurons during visual stimulation, working memory, and attention.
Recent studies suggest that trial-to-trial variability of neuronal spiking responses may provide important information about behavioral state. Observed changes in variability during sensory stimulation, attention, motor preparation, and visual discrimination suggest that variability may reflect the engagement of neurons in a behavioral task. We examined changes in spiking variability of frontal...
