Memories are stored in the brain through the strengthening of connections between neurons, forming neural pathways. Skills are stored similarly, with repeated practice and reinforcement leading to the creation of specific neural networks dedicated to that skill. Both memories and skills are encoded in different regions of the brain, depending on the type of memory or skill being stored.
Memories outside of conscious awareness are often referred to as implicit memories. These are stored memories that can influence behavior and emotions without being consciously recalled.
Short term memories are typically stored acoustically or phonologically, which means information is stored based on its sound. This type of encoding makes it easier to remember information by repeating it verbally in our minds.
