Periods 1-3  Neuroscience of Addiction  My plans for our guest teacher today:   

Today we will get ready for our “worms on drugs” lab.  It is a short period (due to Bring Joy to a Child) .  Pass out labs to the students and have them take 10 minutes to read the lab.


  • In their notebooks (or on onenote if they wish) have students complete the title, date and goals for the lab.  Then have them watch the short video on how to take a worm “pulse.”
  • Answer question 1 based on the video
  • Watch the next video and answer question 6 (there is no question 5- sorry!)
  • Next class students will complete this experiment. We will have 5 different solutions for the worms.  They will be coded A- D.   One will be pond water, one will be nicotine, one will be ethanol, one will be an opiate and non-opiate pain killer.  Neither the worm nor the student will know which solution is which.   All solutions are worm grade (they are such a low concentration that they could not affect a human).


There will probably be time left at this point.  Students can start our next lesson, Opiates


Students should include objectives and guiding questions.  The guiding questions should be answered in full sentences.  Due next class.  Students should also complete their “drug cheat sheet” for opiates.

Tuesday, November 27th-

Dr. Susan Hakeman,  Psychiatrist  will talk to our class about how she treats patients suffering from depression, anxiety and other mental health problems.  There will be time for great questions from the audience.  Take good notes.  Ask questions.

Tuesday, October 30th-

Nicotine addiction and genetics-

Why are some people more likely than others to become addicted to nicotine?  A look at some potential factors .

Look at the following site:

Click on “genes and addiction”-  read this short article and describe the complex interaction between genetic and environmental traits that contribute to a person’s risk of becoming addicted to a drug.

  •  Next click on “Pedigree Investigator”  We will look at a pedigree of a family that has a particularly high rate of nicotine addiction.  We will complete a pedigree w/s with this
  • Next click on “Discovering Addiction Genes” and read.  There is no one gene that can predict whether or not someone will become an addict.  Why?
  • Once gene that can affect the addiction rates of nicotine users is a CYP protein.  Read the following abstract and summarize.
  • Finally, we will get out the models of pre-synaptic and post-synaptic neurons that have AcH receptors.  We will model an action potential that ends at a synapse also containing nicotine.  We will add a CYP enzyme to help break down nicotine and discuss how this enzyme may look different in different people.  Genes do play a role in how a drug is metabolized.


Friday, October 26th

Brain Anatomy pre-assessment

Monday, January 22nd–  The final.

You may use your drug cheat sheet to write anything about the topics listed on that sheet.  Everything must be handwritten but you may print out a new copy if you wish to add more info about any section.


Drug Cheat Sheet :  cheatsheet

Study Guide:  (Informal) –  Review unit 1-4 tests.  The final will include the following topics:

  1.  Basic brain parts
  2. Basic parts of a neuron
  3. How neurons communicate with each other (Na+/K+ /Cl-/Ca+) are all ions that are important in this process.
  4. Neurotransmitters commonly used in this class (Dopamine, Seratonin, Glutamate, GABA, AcH)
  5. Reward Pathway- and things that influence it
  6. Drugs on “cheat sheet”  How each of these drugs affects neuron-neuron communication
  7.  Why dose, age, method of administration, and frequency matter!  Example:  chewing coca leaves during religious ceremonies vs. snorting cocaine, vs. smoking crack cocaine.  Short and long term outcomes of each.  Example 2:  5% THC joints vs. 50% THC “oil”  used in edibles.   Possible Short and long term outcomes of each

Thursday, January 18th-  Individual projects due!  Class presentations (for extra credit).

Friday 9/23/16

Part 2:  The synapse.  On Wednesday we discussed one type of neurotransmitter that bonds to a receptor on the post synaptic neuron.  This resulted in Na+entering the post synaptic neuron through a gated channel and if the cell became positive enough, the electrical signal (action potential) would travel through the axon.  These are called excitatory neurotransmitters

Today we will look at neurotransmitters that cause Cl- gates to open.  This results in the cell becoming even more negative, (hyperpolarized) and even further away from an action potential.  These types of NTs are called “inhibitory neurotransmitters” and prevent a message from continuing across the post synaptic neuron.

HW continue working through lesson 5.  Review page 1 of lesson 5 to see if you know all vocab and objectives.  Pick up a study guide on Monday.

Wednesday 9/21/16

Activity 3-2a: Mapping Brain Regions by Imaging

Another way to associate brain anatomy and brain function is to use imaging, or brain scans. Two types of neuroimaging are regularly used, and an understanding of each will allow you to better understand how the technique helps us map the brain. The techniques are Positron Emission Tomography, or PET scan, and Magnetic Resonance Imaging, or MRI analysis.

Lesson 5 intro

You will have class time to work on these activities.  Whatever you do not finish will be homework that is due on Monday

Wed/Thur 9/30 and 10/1

Communication between neurons.  This involves both an electrical stimulus and a chemical one.  If the electrical stimulus is strong enough, neurotransmitters (chemicals such as dopamine) are released from the pre-synaptic knob of one neuron and into the synapse (space between 2 neurons).  If enough neurotransmitters bind to receptors on the post synaptic neuron, then the electrical stimulus will be transmitted through the axon of the second neuron and the process can continue.  Today we will be modeling the this electrical component of neuron communication, called the  ACTION POTENTIAL

This activity must be done in class and the instructions are in the hanging files.

If you would like additional information, resources and activities on the action potential, you may complete all or part of activities 4-7, 4-8 and 4-9.

  3. Work on Nervous system booklet pag 6/ PET and MRI scans (instructions in book)

Activity 3-2a: Mapping Brain Regions by Imaging

Another way to associate brain anatomy and brain function is to use imaging, or brain scans. Two types of neuroimaging are regularly used, and an understanding of each will allow you to better understand how the technique helps us map the brain. The techniques are Positron Emission Tomography, or PET scan, and Magnetic Resonance Imaging, or MRI analysis.

Start by viewing the following video, which shows a methamphetamine user getting a brain scan to look at his brain before and after methamphetamine use.

  • What kinds of questions did Dr. Volkow ask the subject prior to performing the brain scan?
  • When she explained the brain scan to the subject, what did the red areas show/how did she interpret his scans?
  • She showed the subject an MRI scan and a PET scan. Which one showed more detail about specific cells and molecules?
  • What general brain area does she point out to the subject that shows a difference compared to the “normal brain”? (inside or outside? left side or right side?)PET Scans
  • PET scans are very specific in that they use a particular, radioactively labeled molecule and examine where that molecule localizes in the brain. Frequently, the molecule examined is glucose. Glucose utilization helps us know which areas of the brain are most active (active cells metabolize glucose efficiently).
  • Don’t get bogged down in worrying about what dopamine and the reward pathway are yet.

Activity 3-2b: Mapping Brain Regions by Imaging


MRI Scans

MRI scans are specific for a very different reason. Rather than using radioactively labeled tracer molecules, the MRI relies on the fact that different tissue types in different states of activity will respond differently to a magnetic field. The magnets are used to alter the alignment of subatomic particles. When the magnet is switched off, the electrons return to their normal state at different rates. Thus some tissues will remain aligned while others do not. Alignment will vary based on cell types in the region as well as cell activit
