Transcript

Slide 1-

DAY 5: How do cells in the brain communicate? What are the major chemicals in the brain that affect behavior?
Slide 2-

Review of Memory What did we learn about different types and phases of memory? What did we learn from HM?
Slide 3-

Neurons Cells in the brain that carry messages through signals to other parts of the brain.
Slide 4-

1. Label the parts of the neuron. NEURON ACTIVITY 2. Describe how a signal travels through a neuron to the next neuron. __________________________________________________________________________ __________________________________________________________________________ Dendrite Cell body Nucleus Myelin Sheath Axon Axon terminal Synapse
Slide 5-

Connections between neurons Dendrites = Take in information Axon = Send out information How does the brain work? Synapses!
Slide 6-

Let’s go deeper… What’s happening at a synapse? Chemical release from one neuron to another Packages of chemicals (vesicles of neurotransmitters) are released from one neuron Another neuron receives the chemicals (receptors) Neurotransmission
Slide 7-

Neurotransmission Neuron 1 NEUROTRANSMITTERS Chemicals in vesicles that get released Examples: dopamine, serotonin Neuron 2 RECEPTORS Receivers for specific chemicals Examples: dopamine receptor, serotonin receptor
Slide 8-

Normal Neurotransmission (Dopamine signals reward) T R R DA Pre-synaptic neuron Post-synaptic neuron
Slide 9-

Neurotransmission Game! Roles: Electrical signal Vesicles (containing neurotransmitters) Receptor Messenger Transporter Acting it Out: Electrical Signal > Vesicle > Receptor > Messenger Messenger > Receptor > Neurotransmitter > Transporter
Slide 10-

Short break
Slide 11-

Neurotransmitters in your body Glutamate – excites neurons to fire, involved in memory GABA – inhibits (stops) other neurons from firing Serotonin – affects mood Dopamine – involved with feeling reward, learning, & emotion Acetylcholine – involved with memory & attention &muscle action Norepinephrine – involved with alertness
Slide 12-

What do you predict happens when these are out of balance? TOO MUCH leads to migraines or seizures TOO LITTLE leads to seizures, tremors, & insomnia TOO LITTLE leads to depression TOO MUCH leads to schizophrenia. TOO LITTLE leads to tremors and decreased mobility in Parkinson’s & ADHD Alzheimer’s decreases the amount of this TOO LITTLE can cause depressed mood and cause attention deficit problems
Slide 13-

Neurotransmitter Challenge In a group of 3, pick one neurotransmitter. Learn how it operates in the brain normally. Learn what happens if it’s out of balance. Does this result in a different mood status? Does this result in a disease or disorder? With your group, act out a modified version of the Neurotransmission Game to simulate your neurotransmitter working normally and abnormally.
Slide 14-

An example – Glutamate & Epilepsy T R R Pre-synaptic neuron Post-synaptic neuron
Slide 15-

Neurotransmitter Challenge Choose from the following neurotransmitters: Serotonin Dopamine Acetylcholine Norepinephrine
Slide 16-

Reflection Time Think about what you did and learned today. What does that make you think? Where do you feel confused? What are you still curious to learn more about?
