Highlights •Twenty minutes of direct-current stimulation improved visual acuity by ∼15% •Stimulation changed the amplitude of visually evoked potentials •Subjects with the lowest acuity benefited the most from stimulation

Stimulating the visual cortex of the brain for 20 minutes with a mild electrical current can improve vision for about 2 hours, and those with worse vision see the most improvement, according to a Vanderbilt University study published this week in Current Biology. A/prof Geoff Woodman said...
