Memory formation is the process by which our brains encode, store, and retrieve information. It begins when we experience something new, and our brain takes in sensory information. This information is then transformed into a format that can be stored, often involving structures like the hippocampus, which plays a crucial role in forming new memories. Once information is encoded, it can be stored in different types of memory, such as short-term memory and long-term memory. Retrieval occurs when we recall or recognize this stored information, allowing us to use our memories in daily life. This entire process is essential for learning and adapting to our environment.
