When you remember something, your brain probably stores it by creating new nerve connections.
You have three types of memory – sensory, short-term and long-term.
Sensory memory is when you go on feeling a sensation for a moment after it stops.
Short-term memory is when the brain stores things for a few seconds, like a phone number you remember long enough to press the buttons.
Long-term memory is memory that can last for months or maybe even your whole life.
Your brain seems to have two ways of remembering things for the long term. Scientists call these two different ways declarative and non-declarative memories.
Non-declarative memories are skills you teach yourself by practicing, such as playing badminton or the flute. Repetition establishes nerve pathways.
Declarative memories are either episodic or semantic. Each may be sent by the hippocampus region of the brain to the correct place in the cortex, the brain’s wrinkly outer layer where you do most of your thinking.
Episodic memories are memories of striking events in your life, such as breaking your leg or your first day at a new school. You not only recall facts, but sensations too.
Semantic memories are facts such as dates. Scientists think these are stored in he left temporal lobe, at the front left-hand side of your brain.
