The external stimulus generates neural impulses in sensory organs during encoding which helps to receive the information and process it in different areas of the brain, in order to derive a meaning and represent it to be processed further.

(ii) Storage − It is the second stage of memory in which the encoded information is stored and retained over a period of time to be used later.

(iii) Retrieval − It is the third stage and refers to bringing the stored information into awareness in order to be able to perform the cognitive tasks.
