Presentation Transcript

Do Now: 2 things

  • Write down today’s Focus Question:

  • How does the “lock and key” analogy fit into the functioning brain?

  • Grab a blank brain from the stool and a marker

  • Slide the blank brain into your whiteboard


    • The lobes (incl. the prefrontal cortex)

    • The major function of the four lobes

    • The cerebellum & brain stem

Homework: Edmodo Sign-Up

  • What is it? A “social-networking” site for our classroom

  • Why? Because now you can watch lobotomies in the comfort of your home

  • How? Go to and enter the “Group Code” when you sign up for an account

    HB 5: jlhp60

Neurons, Chemical Transmission, and Neurotransmission





Tuesday 11/13: As you come in…

  • Grab a review sheet for the quiz on THURSDAY

  • Today

    • Quickly revisit NTs

    • Balance of NTs

    • NT drawings

    • Vote

So what about the neurotransmitters?

  • Chemical messengers that carry a specific type of message

  • Scientists have identified around 50 different neurotransmitters

    • But there are many more

  • Each plays a specific role and function

    • Sleep, move, laugh, concentrate, slow down brain! Move faster brain!


  • Why does serotonin make you happy?

    • Scientists are still not sure why, but they do recognize that there is a relationship between neurotransmitters and cognitive function

  • Correlation!

Your Task: Create a Movie Star Poster for ONE Neurotransmitter

Neurotransmitter Balance

Need for Balance: Too much

Excess of Neurotransmitters can lead to disease in humans

  • Glutamate: Lou Gehrig’s Disease

  • Dopamine: Schizophrenia

Need for Balance: Too Little

Deficiency of neurotransmitters can also lead to disease such as:

  • Dopamine: Parkinson’s

  • Acetylcholine: Alzheimer’s

  • Norepinephrine: Depression, ADHD

  • Serotonin: Depression, bulimia, OCD


Disrupting the balance: drugs

  • Both medication and illegal substances can mimic neurotransmitters in the brain

    • Schizophrenia meds: blocks dopamine

    • Black widow spider venom: increases acetylcholine (muscle contractions)

    • Heroin: decreases GABA, which increases dopamine

Wednesday, 11/14 as you come in…

  • Take a Traumatic Brain Injury Worksheet from the stool

  • Write down today’s focus question: In what ways is the brain affected by injury?

  • Begin working on the TBI worksheet

    • I’ll pass out the NT review guide (thanks 2nd period!)

    • I’ll collect the Resilience Assignment

  • EdmodoReminder: Sign up for Edmodo by Friday!!!

    • Group keys: Human Behavior 2nd period: 1u732z Human Behavior 5th period: jlhp60

    • Incentive: Starting with TODAY’s article, you will receive 2 points on an assessment if you read and COMMENT (3-5 sentences) on the article

What is Traumatic Brain Injury (TBI)?

  • A TBI is caused by a bump, blow or jolt to the head or a penetrating brain injury that disrupts the normal function of the brain

  • 5.3 million Americans are living with a TBI related disability

  • Falls are the leading cause of TBI

  • Motor vehicle crashes result in the largest percentage of death from TBI (31.8%)

What are the types of TBI?

  • Ranges from “mild” TBI – brief change in mental status

    • Concussions are mild TBIs – not to be taken lightly!

  • To “severe” TBI – extended period of unconsciousness or amnesia

TBI in the military

TBI has been “nicknamed” the signature wound of the Iraq and Afghanistan conflicts

Use of IED (roadside bombs) responsible

What are the effects of TBI – Brain Stem

  • L - Problems swallowing food and water

  • D - Decreased vital capacity in breathing

  • I - Sleeping difficulties

What are the effects of TBI – Cerebellum

  • S - Loss of ability to coordinate fine movements

  • B - Loss of the ability to walk

  • H - Dizziness (vertigo)

What are the effects of TBI – Frontal Lobe

  • C - Difficulty with problem solving

  • F - Changes in social behavior. Changes in personality

  • M - Inability to plan a sequence of complex movements needed to complete multi-stepped tasks, such as making coffee

What are the effects of TBI – Parietal Lobe

  • J - Lack of awareness of certain body parts and/or surrounding space

  • O - Difficulties with eye and hand coordination

  • G – Inability to attend to more than one object at a time

What are the effects of TBI – Occipital

  • R - Difficulty identifying colors

  • K - Production of hallucinations

  • E - Word blindness – inability to recognize words (alexia)

What are the effects of TBI – Temporal

  • N - Difficulty in recognizing faces

  • P - Difficulty in understanding spoken words

  • Q - Difficulty with identification of, and verbalization about objects

Review for tomorrow – Bingo:

  • Using your review guide from yesterday, write down ANY of the specific terms into your bingo boxes

  • Then, slip your bingo board into your whiteboard
