Working Memory.
• The executive part of Working Memory involves the prefrontal lobe.
• The verbal part --- such as rehearsing words or numbers silently --- involves the speech areas of the cortex (especially the dominant hemisphere). E.g., Broca and Wernicke's areas.
• The visual part --- such as visual imagery to think about how to walk from one place to
another --- seems to involve visual regions, including the occipital lobe.

Longterm Memories. Longterm memory functions are widely distributed throughout the brain, For example, perceptual memory involved perceptual regions, while executive memory, such as plans for future actions, engage frontal regions .

Selective Attention and Conscious (reportable) Events. • Attention improves our ability to perceive stimuli. In the case of
executive attention, the executive regions of the prefrontal lobe shapes perceptual activity in the posterior half of cortex.
• Conscious events seem to mobilize frontal and parietal regions of
cortex.
