1. The brain

2. Parts of the Brain The brain is largely not understood!
There are many regions of the brain that we don’t know what they do

3. Brain Stem
Breathing
Digestion
Circulation
Heart beat

4. Cerebellum
Walnut sized lobe
Controls movement, balance, coordination

5. Cerebrum This is the largest part. It is divided into four lobes
Frontal- reasoning and thinking, motor skills
Parietal- processing tactile sensory information such as pressure, touch, and pain
Temporal lobe- interpreting sounds and the language we hear, memory formation
Occipital lobe- interpreting visual stimuli and information

6. HypoThalamus
Temperature control
Thirst and hunger

7. Amygdala
Emotion, especially fear
The fight or flight response

8. Sight Humans heavily rely on sight as our primary sense
The occipital lobe is responsible for interpreting what we see
Sometimes our eyes deceive us though because…
Our brain interprets the signal weirdly
We have trained ourselves to look at things a certain way
Or both!

15. Color and light
Color is detected by cones. We have three kinds: red, blue and green.
Light is detected by rods

Blindness can be caused because a part of your eye does not work, or it does not communicate with the brain
