• We tend to think of our memories as discrete items summoned up by associations which are often words or some other cognitive construct
• In reality a memory is comprised of cognitive, emotional, sensory and movement components that are linked because they most often occur together or in sequence
• While some associations are unilateral, some are bi-lateral

The concept applies to functions that are located near each other in the brain or have shared or common pathways

• Activating one area of the brain can activate others nearby or connected areas
• This is the underlying reason why changing inputs can change outputs
