Currently intraoperative monitoring using somatosensory evoked potentials has been widely recognized to prevent iatrogenic spinal cord injury. Previous studies only reported the monitoring effects of somatosensory evoked potentials after mechanical factors-caused spinal cord injury. However, spinal cord injury is not only triggered by mechanical factors, biochemical factors and vascular factors may cause spinal cord ischemia-reperfusion injury. It remains unclear whether spinal cord...

Negative motor evoked potentials after cerebral infarction, indicative of poor recovery of limb motor function, tend to be accompanied by changes in fractional anisotropy values and the cerebral peduncle area on the affected side, but the characteristics of these changes have not been reported. As reported previously, the lower limit value of fractional anisotropy of the cerebral peduncle in healthy volunteers is 0.36, and the lower limit of the asymmetry of the cerebral peduncle area is...

PINE BROOK, N.J., July 30, 2012 /PRNewswire/ -- Vision Problems in infants and pre-verbal children are a challenge for ophthalmologists and optometrists to diagnose and manage. Many vision tests look at just the structure of the eye or require a verbal response which many children are either unable or unwilling to give. Dr. Sean Donahue and colleagues at Vanderbilt Eye Institute in Nashville, TN recently presented a poster, Visually Evoked Potential Detection of Amblyopia in the Clinic, at...

PINE BROOK, N.J., June 21, 2011 /PRNewswire/ -- A recent paper published in the Journal of Glaucoma shows a new visual evoked potential (VEP) technique to be a fast, objective method to screen for functional damage in glaucomatous eyes. The technique, called short duration transient VEP (SD-tVEP), significantly decreases test duration and provides less subjectivity in evaluating results compared to traditional VEP methods. The study was carried out at New York Eye and Ear Infirmary (New...
