An Introduction to the Virtual Neuroscience Lab
Series
Introduction to MeDarci J. Harland• 12 years high school biology/science• Ph.D in Educational Technology • MIND project role:
– Biology expert– Meet with scientists– Story board the modules– Create professional development materials– Communicate with the computer animators– Support teachers who implement our Virtual
Labs2
History of The MIND ProjectThe Vision: Design virtual online
laboratories Bringing cutting edge science &
research into the high school classroom
Provide realistic simulation science experiences
NIH grant: SEPA3
Virtual Neurotransmitter
Lab: Cocaine Study
A look at the role of dopamine in the brain through current
research.
Introductory Video Ways to implement
Use animated graphics Individual or groups Teach scientific method
& data collection Quizzes
Virtual Neuroscience Lab #1: Cocaine Addiction Lab
5
Objectives Describe the 2 stages of motivation in
behavior. Identify the location and function of
dopamine neurons in the brain. Identify the role of dopamine in behavior. Describe the possible role of dopamine in
drug addiction.
A Review of Neuronal Signaling How do neurons communicate with each
other?
Neurotransmission model
Dopamine Neurons in the Brain
Based on these diagrams, what parts of the brain does dopamine affect ? What impact does this have
on the organism?
Dopamine in the Brain Dopamine neurons terminate in the
nucleus accumbens The nucleus accumbens’ output neurons
terminate in the prefrontal cortex The prefrontal cortex contains the limbic
system, which is the center of the brain for pleasure, pain, anger, rage, panic, aggression (fight-flight-freeze responses), and basic sexual responses.
Dopamine and Cocaine Cocaine blocks the dopamine receptors on
the axons of neurons Dopamine that is released can not be
taken up The excess extracellular dopamine alters
the individual’s state of mind, resulting in a “high”
Dopamine & Behavior Log into the Virtual Neuroscience Lab #1 –
Cocaine Study Click on “Desk Area” Read Book 3, Chapter 1 and answer the
first 5 pre-lab questions in the virtual lab notebook
Pre-lab Questions (Virtual Lab Notebook)
1. What are the two phases of motivated behavior?
- Appetitive and Consummatory
2. What is known about the effects of cocaine on dopamine levels in the brain?
- Cocaine increases the levels of dopamine in the brain
Pre-lab Questions (Virtual Lab Notebook)
3. What is the hypothesis being tested in this experiment? - Dopamine levels will increase during the cocaine seeking phase of behavior.
4. If the hypothesis is true, then what should you observe?
- Dopamine levels should go up when the rat is looking for cocaine (before it gets cocaine).
5. What is the name of the method used to measure dopamine levels?
- Fast scan cyclic voltammetry
Activity Perform the cocaine study and write your
article.

The Virtual Stroke Lab
Virtual Neuroscience Lab #2: StrokeIntroduction Video
Student Experience: Video game feel with information given only when needed
Students can do this individually, small groups or as a demo.
Virtual Neuroscience Lab #2: Stroke (cont.)
Web-based, no special software needed
Information in EMR: facts students use to make decisions.
Professional Development: answers, implementation ideas, and standards
Objectives Describe stroke symptoms Choose primary & secondary diagnostic
tests for a specific patient. Interpret the results of a CT scan & CT
angiogram to identify the area of the bleed & structure of an aneurysm.
Perform a scientific procedure to save the life of our patient.
Introduction to Stroke (students) What happens when blood can’t get to
certain areas of the body?
Lung cells die; can’t exchange CO2 & O2Heart cells die; part of heart can’t pumpBrain cells die; brain neurons can’t send impulses
Kidney cells die; can’t remove wastes
Pulmonary embolus
Heart attack; myocardial infarction
Stroke
Renal vein thrombosis
Activity #1 Log on and complete the Virtual Stroke
Lab as a student Take your time, and enjoy the lab
