What is the limbic system
200
The resting state of a neuron is about __________ mV.
What is -70

These two neurotransmitters are also produced as a hormone near the kidneys. They are used to "kick up" energy for the body. It is related to adrenalin.
What is norepinephrine?
200
Schizophrenia is most closely linked with excess receptor activity for the neurotransmitter _____.
What is dopamine
300
A layer of fatty tissue encasing the fibers of many nuerons: enables vastly greater transmission speed of neural impulses.
What is myelin sheeth
300
Which part of the brain controls the pituitary gland?
What is the hypothalamus

The _____________ level for a neuron to fire an Action Potential is -55 mV.
What is Threshold?
300
A drug that acts to mimic or increase the amount of a specific type of neurotransmitter in the synaptic gap is called an _______.
What is an agonist?
300
When a patient has Parkinson's, she/he is low on _____?
What is dopamine
400
With regard to the process of neural transmission, a refractory period refers to a time interval in which a segment of the _____ is unable to transmit an electrical signal.
What is an axon
400
Just like Phineas Gage, damage to your ______ lobe will not kill you, but will change your _______
What is frontal/personality
400
A segment of an axon may reach -80mV during the __________ _________.
What is refractory period.
400
This type of drug blocks (corks) receptors in the emitting neuron so excess neurotransmitter (of a specific type) can't be reabsorbed. These drugs are called
What is a reuptake inhibitor?
400
Animal research has revealed a general reward system that triggers the release of the neurotransmitter ______.
What is dopamine
500
The peripheral nervous system is to sensory neurons as the central nervous system is to _______
What is interneurons
500
A picture of a cat is flashed in the left visual field and a picture of a mouse is flashed in the right visual field of a split brain patient. The individual will be able to use her right hand to indicate she saw a ______
What is a mouse
500
Dendrites receive chemical info from neurotransmitters coming from pre-synaptic gap neurons. These produce tiny electical changes in the neuron, some adding and some subtracting the neuron's electrical charge. These + and - charges accumulate in the neuron's ____________ until the neuron reaches a charge of ___
What is axon hillock, and -55 mV?
500
This neurotransmitter is involved in memory production and also motor (muscle) movement. Black Widow venom causes a sudden release of this neurotranmitter, effectively paralyzing it's victims.
