Background:
Focusing on low-level perceptual activities, and robust, controlled explorations with medium-sized cohorts, several studies have shown tACS effects related to oscillatory activity and inter-regional synchrony.
For example, in healthy subjects, occipital tACS showed an increase in
Methods:
Design: The DIRECT ANGIO trial is a French academic, investigator-initiated, multicenter, controlled, open-label, blinded endpoint, two-arm randomized, clinical trial to compare the effectiveness and safety of direct angio-suite admission versus the standard radiological or emergency
Visual functions are widely distributed over large areas within the cerebrum. Secondary to such wide distribution, visual field defects (VFD) are a common outcome of brain insults especially cerebrovascular stroke whether hemorrhagic or ischemic. Among these, homonymous hemianopia is the most
Stroke or unsufficient cerebral circulation is a non-traumatic disease due to occlusion or rupture of brain blood circulation characterized by neurological deficits such as loss of motor control, cognitive impairment, oral disorder or sensory changes in one half of the body resulting from changes.
Visual field defects after posterior cerebral artery stroke can be improved by vision restoration training (VRT), but when combined with transcranial direct current stimulation (tDCS) which alters brain excitability, vision restoration can be potentiated in the chronic stage. Because it is possible
Hypothesis: Intranasal insulin will improve post-stroke cognitive impairment if administered in the early post-acute stroke phase compared with placebo.
Design: Block randomized, double-blind placebo-controlled trial of 40 patients, 20 per group.
Study population: Ischemic stroke patients presenting

Methodology
Sampling:
Convenient sampling will be conducted to all in and out-patients with stroke referred consecutively to occupational therapy department in Kowloon Hospital during the data collection period. Patients who meet the following inclusion criteria are admitted for study.

Background
Purpose and Experimental Design Reading a line of text is usually achieved by planning a series of saccades, which allow the eyes to jump from one word to another (reading scan-path). Arabic readers use peripheral visual information to the left of the word in order to plan their reading
In this study of patients suffering an aneurysmal subarachnoid hemorrhage (SAH) we would like to validate former results from CSF studies through microRNA profiling investigate the pathophysiological mechanisms that lead to systemic complications such as cardiac dysfunction, acute lung injury (ALI)
Study design: A PROBE (Prospective, Randomized, Open-label, Blinded-endpoint) design
Methods:
1. Visual perceptual learning (VPL) group
1. Visual perceptual learning (24 times for 2 months, 3 times per week) in visual field defect areas
2. At baseline and post-VPL evaluations (2 months after):
In this study of patients suffering an aneurysmal subarachnoid hemorrhage (SAH) we would like to investigate the pathophysiological mechanisms that lead to the phenomenon delayed cerebral ischemia (DCI).
We will accomplish this through analyzing the profile of microRNA expression in the
The specific aim of this study is to improve recovery of visual function after brain injury. A prominent theme of current neuroscience research regarding the sequelae of brain injury posits that activity-dependent plasticity underlies neuro-recovery. If that is the case, there is good reason to
