What is Aphasia?
This is when a person has some brain damage that results in deficits of speech
100
What does the Temporal Lobe do?
Higher level audio and visual processing
100
What is # 3? What step of Neurotransmission occurs here?
The Synapse and Termination
100
How does Marijuana block pain?
Marijuana is a Glutamate Antagonist and glutamate is the NT that is involved with pain, so blocking Glutamate blocks pain
100
What is Number 4?
The Hypothalamus
200
What is Localization of function?
Each region of the brain plays a specific role in behavior
200
Spinal Cord
Contains ascending and descending neuronal pathways of motor, sensation, and pain
200
What makes the Myelin? What kind of cell is it?
Oligodendrocytes - Glial Cell
200
Why are Amphetamines and LSD awful?
With one use, they can wipe out almost all of the neurons in your brain
200
Which is the Parietal Lobe?
Number 1
300
What is Lateralization of function?
Some processes of behavior are conducted by a single hemisphere
300
Where emotions are regulated
Amygdala
300
Where is synapsin located?
Number 6
300
Where does Nicotine have its effect? Why?
On the Dendrite to start because it is initially excitatory
300
Where the two hemispheres are connected
The Corpus Callosum is number 5
400
What is Distributive Processing?
This is when different parts of the brain communicate and work together to get a function
400
Why is the Frontal Lobe called the Executive Command Center?
It is in charge of our decision making processes regarding language, motor, and emotional responses
400
Explain why Multiple Sclerosis is bad. As in, what it does and how we can treat it.
MS is a virus that acts like Myelin and attaches to it, the body fights it of by destroying it but then they accidentally destroy myelin resulting in loss of functions in cells. We can treat it with Copolymer A which looks like MS and thus the cells attack that instead of what is in the brain
400
How does Caffeine work?
It works by blocking the Calcium channels and if calcium can't get in the nerve ending, then the NT Adenosine (Which tells us to be tired) cannot be released and so we stay more awake/alert
400
What is all in the Midbrain?
Number 1 - Periaquaductal Grey, Substantia Nigra, and Colliculi
500
How was our Cerebellar Patient able to learn motor skills?
The tumor was from birth, so as she was growing up, her right cerebellum did all of the learning for the left half, and so when the tumor was removed, there was no detriment because the brain already adapted
500
How do the Raphe Nucleus and Dorsolateral Pons work together?
The Raphe Nucleus releases serotonin to put us to sleep and the Dorsolateral Pons creates the effect of Atonia so we do not act out our dreams, then the Raphe releases norepinephrine to wake us up again
500
Explain the Trigger Step (In-Depth/Give me an A answer)
This is at the Axon Hillock, where the Action Potential is first created, Sodium comes in and sends the charge just above the absolute threshold which opens up the Sodium Channels for a huge influx of sodium that creates the action potential, then the Sodium Potassium Pumps activate and pump out sodium and pump in potassium to return the charge to baseline
500
Explain how Cocaine works...
It is a Dopamine Agonist and blocks the reuptake of Dopamine, allowing it to continually have its effect, and then cocaine stimulates dopamine receptors as well and "caps" or knocks out the receptors as it leaves
500
What is #6 and its function?
That is the Pituitary Gland and where hormones are stored and where the endocrine system begins
