TORONTO, April 20, 2016 — Who will win the women’s singles tennis title at the 2016 Rio Olympics this August? That’s a question recent York U brain research can help answer. The new study shows that when doing a visual task, neural activity in the frontal cortex initially reflects the visual goal accurately but errors accumulate during a memory delay, and further escalate during the final memory-to-motor transformation. “Think of all the times you see something and plan to act on it, but after only a short delay you make a mistake,” explains Professor Doug Crawford. “For example, before my morning coffee kicks in, I’m great at making silly mistakes, like putting the honey away in the fridge instead of the peanut butter.” For the study, published online at eNeuro,…
