What is the difference between presynaptic and postsynaptic neurons?
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
What a neurotransmitter is?
A neurotransmitter is a chemical or peptide in synapses, usually between neurons, a neuron and muscle or a neuron and other organ. The neurotransmitter transmits information to and from and within the brain. When a neurotransmitter is released from the presynaptic cell in response to depolarization of the cell by an action potential, it diffuses across the synaptic cleft and binds a receptor or ligand-gated ion channel on the postsynaptic cell. Binding on the postsynaptic cell alters the resting potential of the postsynaptic cell in either an inhibitory or excitatory manner, making the cell less susceptible or more susceptible (respectively) to an action potential. Examples include, but are not limited to, acetylcholine, GABA, noradrenaline, serotonin and dopamine.
A virus causes damage to the sodium channels of the postsynaptic neuron such that they open very slowly in response to a neurotransmitter How does this modify the generation of an action potential?
The sodium influx necessary for depolarization will occur more slowly making the action potential difficult to generate.
What are characteristics of neurotransmitters?
Neurotransmitters are released in response to stimulation. They alter the physiology of the postsynaptic cell. They are synthesized by a presynaptic neuron. They bind to specific receptors on the postsynaptic cell.
Which neurotransmitter is associated with the control of the pain response?
Endorphins
Which neurotransmitter helps your body return to normal after the stress response?
The neurotransmitter that helps the body return to normal after a stress response is the noradrenaline. It is also used to raise blood pressure.
What neurotransmitter stimulates the fight or flight response?
Norepinephrine and epinephrine (adrenaline).
What determines whether the response of a receiving neuron is excitatory or inhibitory?
The type of neurotransmitter.
How the person making an argument influences the response to it?
Yes
What type of ions moves into the cell in response to this neurotransmitter?

Because enkephalins and endorphins often alter a cell's response to a neurotransmitter they are called neuromodulators?
TRUE.
In operant conditioning the stimulus is the behavior of the animal and the response which influences whether or not the behavior is likely reoccur can be under human control-true or false?
False. The stimuli is the thing, sound, or activity that influences the response. The response is the conditioned response, assuming it occurs every time the stimli is present.
