Humans have big brains and our frontal lobes, just behind the forehead, are particularly huge. Injuries to this part of the brain often happen after blows to the head or a stroke. Paradoxically, some people with frontal lobe injuries can seem unaffected – until they’ve been carefully evaluated. The frontal lobes are sometimes described as the executives of the brain, or conductors of the orchestra. Among other things, they control and organise our thinking and decision-making processes.
