1. Parts of the Brain

2. Control center for the body Runs everything the body does
Function of the brain
Organ in the body that allows: thought, emotions, movement, dreams, etc.
Control center for the body
Runs everything the body does

3. Makes up 85% of the brain’s mass/weight
Cerebrum
Makes up 85% of the brain’s mass/weight
Thinking part of the brain
Controls your voluntary muscles (those muscles you have control over)

4. Frontal lobe True center for control in the brain
Responsible for reasoning, problem solving, judgment, impulse control, motor control, memory and higher level emotions (empathy and altruism)
Last to develop when a young adult
Front part of cerebrum

5. Parietal Lobe Responsible for processes such as pain and touch
Also responsible for movement, speech, recognition, orientation, and cognition (calculating the location and speed of objects)
Found directly behind frontal lobe in cerebrum

6. Responsible for visual sense and processing
Occipital Lobe
Responsible for visual sense and processing
Found at back of cerebrum

7. Temporal Lobe
Responsible for auditory (sound) sensation and language recognition
Also involved in emotion, memory, and speech
Found below other parts of cerebrum and towards center of brain

8. Neural bridge connection both hemispheres
Corpus Callosum
Neural bridge connection both hemispheres
Located in the center of the brain
Hypothesized that right have of brain controls left half of body and vice versa

9. Controls balance, movement, posture, and coordination
Cerebellum
Controls balance, movement, posture, and coordination
Also involved in learning movement
Found at the back and bottom of the brain

10. Brain stem
Responsible for all functions your body needs to stay alive (such as breathing, digesting food, circulating blood, etc.)
Controls all involuntary (you have no control over) functions

11. Pons Responsible for level of arousal and consciousness, and sleep
Also relays sensory information to/from the brain
Also involved in controlling autonomic body function (things you don’t think about)
Top half of brain stem

12. Also relay station for nerve signals going/to and from brain
Medulla oblongata
Helps body control autonomic functions (like respiration, digestions, and heart rate)
Also relay station for nerve signals going/to and from brain
Bottom half of brain stem

13. Pituitary Gland
Produces and releases hormones into your body that are linked to growth

14. hypothalamus Linked to pituitary gland to control body functions
Monitors and controls your circadian rhythms (daily sleep/wake cycle), homeostasis (inner balance in body, including temperature), appetite, thirst, other bodily urges and also plays a role in emotions, autonomic functions, and motor functions

15. Thalamus The relay station of the brain
Most sensory signals like sound and vision, go through this organ on their way to other parts of the brain for processing
Also plays a function in motor control

16. Amygdala Latin for almond (which relates to its shape)
Helps in storing and classifying emotionally charged memories
Plays a large role in emotions, especially fear
Trigger responses to strong emotions like sweaty palms, freezing, increased heart rate/respiration, and stress hormone release

17. Hippocampus
Primary role is in memory formation, classifying information, and long-term memory
Also involved in interpreting incoming nerve signals and spatial relationships

18. Neurons and learning
Neurons are the microscopic cells in the nervous system
When new things are learned the messages travel from one neuron to another
Eventually the brain starts to create connections (pathways) between neurons, so things become easier to do
