Brain Regions association with working memory

The working memory, as seen in Baddeley's model, is divided into several components. Each is associated with a different region of the brain.

Phonological Loop

• The phonological store is located in the parietal lobe
• The Articulatory rehearsal component is in both the frontal lobe and the cerebellum
• The speech production area associated with articulatory rehearsal is also known as Broca's area

Visuospatial Sketchpad

• This involves the dorsal and ventral streams
• The visual cache - storage takes place in the occipital and visual cortex
• The inner scribe - spatial rehearsal takes place in the inferior parietal lobe.

Central Executive

• The prefrontal cortex is associated with this component.
• This is the brain region that deals with higher level cognitive tasks.
• Evidence has found activation particularly in the dorsolateral region of the prefrontal cortex.

Episodic buffer

• There is little information available about the anatomical location of the episodic buffer.
• Similarly to the other three components, it is likely to be associated with multiple locations
