Final answer:
The brain, specifically the hippocampus, amygdala, cerebellum, and prefrontal cortex, plays a major role in memory. Neurotransmitters such as epinephrine, dopamine, serotonin, glutamate, and acetylcholine are also involved in memory formation.
Step-by-step explanation:
The brain plays a major role in memory, and there are specific brain regions involved in different types of memory. The hippocampus is responsible for encoding new memories and transferring them into long-term memory. The amygdala is involved in emotional memory and helps determine which memories to store. The cerebellum is involved in procedural memory, while the prefrontal cortex is involved in semantic memory. Neurotransmitters such as epinephrine, dopamine, serotonin, glutamate, and acetylcholine also play a role in memory formation and consolidation.
