Tues Sept 27 and Wed Sept 28Cerebral Dominance, Split Brain

• Objective: Students will explain the parts and roles of the endocrine system, genetic issues, and the different hemispheres.

1. CBM2. Cerebrum/Hemispheres/Lobes3. Notes: Endocrine System4. Exit ticket5. Finish Reading Ch. 2; vocab cards due on day of test6. Test: A-Day Monday Oct 3; B-Day Tuesday Oct 4

Brain Regions

• Hindbrain– Coordinates motor activity,

posture, equilibrium and sleep patterns and regulate breathing and blood circulation.

• Midbrain– Controls sensory processes

• Forebrain– Controls cognitive, sensory and

motor function, and regulate temperature, reproductive functions, eating, sleeping and the display of emotions.

Cerebrum• Divided into hemispheres• Specific strengths/weaknesses• Work together to communicate• Corpus Callosum• Cerebral cortex

HemispheresLEFT

• Controls right side of body• Verbal• Sequential• Logical problem solving• Analytical• Factual• Abstract• Outlining• Details• Comprehending speech &

writing

RIGHT

• Controls left side of body• Visual• Random• Creative• Patterns• Intuitive• Summarizing• Big picture• Music & shapes• Simple commands• Emotions

Cerebrum

Split Brain Operations http://www.youtube.com/watch?v=ZMLzP1VCANo&feature=related

Do the hemisphere have to be connected for a person to function?

How did this operation affect the person?What would be the pros & cons of having this surgery done?

• Plasticity– http://www.learner.org/vod/vod_window.html?pi

d=1575What does this show us about the brain?

Lobes

• Frontal– Motor Cortex– Broca’s area– http://www.learner.org/

vod/vod_window.html?pid=1592

• Parietal– Somatosensory Cortex

• Temporal– Auditory Cortex– Wernicke’s area

• Occipital– Visual Cortex

Endocrine System• Connected with nervous

system(brain pituitary other

glands hormones brain)

• Send messages throughout the body via hormones

• Hormones & Neurotransmitters

Glands

• Secrete hormones• Important glands:

– Pituitary– Adrenal– Pineal– Thyroid– Islets of Langerhans– Gonads

• Gland Issues– Dwarfism/Giantism– Various adrenal diseases– Hypothyroidism/Hyperthyroidism– Diabetes– Sex characteristics

Exit TicketBased on today’s information, answer the

following questions.1. What area of the brain being injured would

have the greatest impact? Why?2. If there was an experimental treatment to

that might help you recover from the injury, would you be willing to try it? Why/why not?
