1. Agenda – Tuesday, February 4th
Biology reading quiz (#4)
Notes over parts of the brain
The cerebrum
The cerebral cortex
Homework: NONE

2. Practice FRQ
4. Assume you are watching a remake of the movie Frankenstein. In the scene you're viewing, the assistant (Igor) is showing Dr. Frankenstein some body parts that he forgot to put in their newly made Sensational Man. Dr. Frankenstein angrily yells at Igor, "You idiot! What will our Sensational Man do without his_______": a.) cones b.) feature detectors c.) optic nerve d.) cochlea e.) olfactory bulb f.) kinesthetic receptors

3. The Cerebrum Outermost structure of the brain
Divided into two hemispheres
Each hemisphere has four lobes
Makes up 85% of the brain’s weight

4. The Cerebrum -- Lobes Frontal ____________________________
Parietal ____________________________
Temporal ___________________________
Occipital ____________________________

5. Cerebral Cortex The gray-matter covering of the cerebrum
Carries on thinking and perceiving

6. Cerebral Cortex Gray matter: No special covering
Controls processing, new thoughts, perception, etc.
White matter: Covered in myelin sheath, which speeds up electric signals
Communicates with the rest of the brain

7. Motor Cortex Controls body movements
Motor cortex in each hemisphere controls the opposite side of the body

8. Hemispheres Left Hemisphere:
Literal interpretation of speech and language
Logical reasoning
Motor control for right side
Processes right side visual field
Objective analysis
Math skills

9. Hemispheres Right Hemisphere: Looks “between the lines” Intuition
“Reading” emotions
Visual & spatial reasoning
Motor control for left side
Processes left side of visual field
Subjective analysis
creativity

12. Agenda – Thursday, February 6th
Finish cerebrum notes
Corpus Calossum
Neuroplasticity
Parts of the brain overview
Driving analogy
Homework: Brain overview analogy due MONDAY

13. Hemispheres
Connected by the corpus callosum

14. Neuroplasticity
Brain’s ability to change and reorganize itself in response to damage (brain “rewires” itself)
Neurogenesis: Brain’s recreation of neurons

15. “Just a shell…driven by mindless instinct”
Hindbrain
Contains most of the brainstem
Oldest part of the brain  “Reptilian Brain”
Processes work outside of consciousness
“Just a shell…driven by mindless instinct”

16. Parts of the Hindbrain Medulla: _________________________
Pons: ____________________________
Cerebellum: _______________________

17. Midbrain Located right above hindbrain
Coordinates simple movements with sensory information

18. Parts of the Midbrain
Reticular Formation: ____________________

19. Forebrain Responsible for most complex behaviors & mental processes
MOST processes here work outside of consciousness

20. Parts of the Forebrain Thalamus: ___________________________
Hypothalamus: _____________________
Hippocampus: ______________________
Amygdala: _________________________
Cerebral Cortex: _______________________
Limbic System

21. Hindbrain Contains most of the Brainstem
Oldest Part of the Brain “Reptilian Brain”
Processes work outside of consciousness
Parts of the Brainstem:
Medulla: Controls Blood Pressure, Heart Rate, & Breathing
Pons: Critical to sleep . Also the “Bridge” to the brain.
Behind the Brainstem
Cerebellum: “Little Brain” that coordinates habitual muscle movements
(Tracking Object w/ eyes, Playing instrument, Ice Skating)
Also Handles Balance & Coordination
Prepare body for possible danger!

22. Forebrain Responsible for more complex behaviors & mental processes
Thalamus: relay center for sensory information except smell
Limbic System (Deals w/ Emotion & Memory)
Hypothalamus: Controls body temp., sexual arousal, hunger,
thirst, & Endocrine System. Also controls
Biological Rhythms & is a reward center.
Amygdala: Provides emotional context for sensory information.
(Linked to aggression & fear)
Hippocampus: Encodes information into long-term memory.

23. Midbrain Located right above Hindbrain
Coordinates simple movements w/ sensory information
Top of the Brainstem
Reticular Formation: Controls level of awareness.
(Without it, we fall into a coma)

24. Walking Dead (S.1, E.6) – 19:00 – 23:30
