Latin for sea horse

It controls memory formation - It decides which memories to form

The hippocampus stores explicit memories, which are of two types:

  • Episodic memories - Memories of events
  • Semantic memories - Memories of facts

Both memories are initially stored as short-term memories. Over time, some of them become long-term memories that are stored in the neocortex

What decides what memories become long-term?

When we learn something at first, it becomes an episodic memory - You don’t remember what you learned but when you learned it

Over time, it translates into a semantic memory - You now remember what you learned rather than when you learned it

  • Repetition - The same neural pathways are being repeatedly activated

Spaced repetition is powerful. This is where we repeatedly activate the same neural pathways in intervals. That’s how we form more long-term semantic memories

Info

Much of the short-to-long term memory encoding and memory formation happens dominantly during sleep

  • Reward or Motivation - The reason for learning what we’re learning The prefrontal cortex and amygdala form the Reward System in your brain
