Oscillating Brain Waves in Visual Cortex Help Sight

"Scientists measuring brain activity have found that in many regions, such as the sensory or motor cortex, activity sometimes oscillates at different frequencies, forming wave-like pattern," according to Medical News Today. "Despite the fact that such oscillations are frequently observed, and present in many brain regions, their functional role remains unclear. Research done by Dr. Christopher Pack, from McGill University, who looked at such waves occurring in a region of the visual cortex of the brain, suggests these oscillations could have a role in resetting the sensitivity of neurons after eye movements. Further results suggest these waves could also have a role in supporting the brain's representation of space. These results were presented at the 9th Annual Canadian Neuroscience Meeting, on May 25th 2015 in Vancouver, British Columbia." Read more.
