A double dissociation occurs when two functions are disrupted separately in two different individuals or regions of the brain. In this example, patient A can read but not write after an injury to one region, while patient B can write but not read after an injury to the other region. This demonstrates a dissociation between the ability to read and write between the two regions of the cortex.
