Brain study on memory delay explains visuomotor mistakes

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, new research indicates. In an Olympics tennis analogy, when a high degree of accuracy is required, a one-second delay in frontal cortex processing could make the difference between an Olympic gold and silver, according to the researchers.
