So far I’ve looked at the reptilian and mammalian brains.
It’s time to look at our third, evolutionarily youngest, brain:
The Pre-Frontal Cortex (PFC)
Our PFC is the large area of the brain situated at the front of our brain and it takes most of the frontal lobes in the right and left hemispheres. This is the part of our brain that gives us much of our intelligence and problem solving abilities.
- last major brain region to evolve in humans
- Accounts for approx. 5% of our total brain volume
- doesn't really come oniine until a person is in their early to mid-20s
- Is the first part of our brain to decline as we grow older
- Has numerous connections with other parts of the brain that control dopamine, norepinephrine and seratonin, three neurotransmitters that are important in mood regulation.
- help you to achieve your goals.
- allow you to connect past experience with present action so you can make decisions
- enable you to apply your memories to new situations in order to make sense of them thus building your acquired frame of reference.
- explains why 2 people can have very different memories of the same event.
