1. Bell Work Describe a neurotransmitter.
True or False: A neuron is a cell.
What is the myelin?

2. Neuron Review

3. CNS vs. PNS

4. You Need:
Brain Diagram
The Brain

5. The Hindbrain Lower portion Medulla – Vital functions
Pons – located in front of medulla, regulates body movement, sleep, alertness/attention
Cerebellum – Rests under cerebrum, involved in balance and coordination

6. Hindbrain Image
Brain Stem

7. The Midbrain Located in the middle Vision and hearing
Reticular Activating System – Begins in hind, travels to fore, important for attention, sleep, and arousal.
Some drugs alter the activity
Loud noises waking/alerting

8. Not Labelled

9. The Forebrain Thalamus Hypothalamus Sensory center, transmits messages
Hypo = below
Regulates body temp, stores nutrients, influences motivation and emotion.
Hunger/thirst
Caring for offspring
Aggression

10. Forebrain Cont’d Limbic System Amygdala Hippocampus
Emotion and Aggression
Hippocampus
Memory
Dory from Nemo – damaged LS

11. Label the Amyg. And Hippo Together

12. Forebrain

13. Cerebral Cortex Cerebrum The part that “thinks”
Biggest cerebrum is in humans
Biggest part of brain
Cerebral Cortex
Surface that is wrinkly
The part that “thinks”
Deals with memory, language, perception, complex motor functions.

14. What makes humans special?
Largest cerebrum (based on body size).
2 hemispheres
Like a walnut
Corpus Callosum connects hemispheres
Opposite from where message is sent
Right = left, Left = Right

16. Four Lobes of Cerebral Hemisphere
What does hemisphere mean?
Occipital Lobe
Sight
Parietal
Perception of “Touch” senses.
Temporal
Hearing and memory
Frontal
Reasoning, planning, logic

17. 4 Lobes On Rights

19. Wrap Up
Why do you think each part of the brain is involved in something different?

20. Right Brain vs. Left Brain
