is the area of the brain at the very front of the frontal lobes. It is involved in "executive functions", such as working memory, decision-making, planning and judgment. Prefrontal regions appear to be particularly sensitive to the effects of aging. It is thought that the reduced ability to recall the context of memories that occurs with advancing age, is evidence that the prefrontal cortex is also critical for context processing - a process involved in many cognitive functions. A recent study has also revealed that emotional stimuli and attentional functions are integrated in a specific part of the prefrontal cortex - the anterior cingulate (located between the right and left halves).
