These complex HealthPerfect.net interactions allow neural circuits to process and encode information, support cognitive functions and control behavior. The neural circuits in our brain are similar to electrical circuits. Canadian psychologist, Donald Hebb, explains memory as a reactivation of the same pattern of neurons that were activated at the time of the original experience. Thinking of the Sahara desert activates one network of neurons, while thinking of rats fires up an entirely different network. Over the years, some of the neurons die or are incorporated into circuits that represent different experiences.
