Abstract: The process by which memories are stored in our brains is not known until today. Therefore, this theory mainly focuses on the process by which memories are stored in our brain. However, it is abstract but linked with common real world phenomenon. Memories can be stored chemically, magnetically, electrically or any kind of way in our brains. It is mentioned that this theory cannot deny another processes but strongly recommends the chemical storing mechanism. According to this theory -- some regions are present in Cerebrum region, which namely Memory Storage Region. Consists of two parts, namely, 1. Factor 2. Cluster of Special Cells (CSC) CSC secretes chemical substances. The Particular Secretory Unit or PSU. This PSU has some categories and each category is involved for a particular sense organ. And some types of chemicals are including in a category. For a particular event, different type of chemicals units of a same category are bound orderly with each other and form a chemical chain. This chain gives a feeling, respect to this event, and stores it in Memory Storage Region of brain as a memory. Initially it is active but gradually loses its energy. Again when it gets charged, it is reactivated. This time animal can remember their previous experience.
