The hippocampus: an overview
  • The hippocampus is the part of the brain that is involved in forming, organizing, and storing memories. It is a limbic system structure that is particularly important in forming new memories and connecting emotions and senses, such as smell and sound, to memories.
  • The hippocampus is a horseshoe shaped structure, with an arching band of nerve fibers (fornix) connecting the hippocampal structures in the left and right brain hemispheres.
  • The hippocampus is found in the brain's temporal lobes and acts as a memory indexer by sending memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieving them when necessary.

  • And if you can connect anxiety to faulty breathing habits, it means you can change the way you breathe and potentially see some improvement.

However, scientists have consistently shown that humans use their entire brain throughout the day.
