How is information carried between neurons?

Information is communicated between neurons through chemicals called neurotransmitters.
 

What are the synaptic vesicles?
 

Synaptic Vesicles: Containers in ends of axon terminals that contain neurotransmitters.

What's usually on a dendrite, and receives neurotransmitters?

A receptor is an area that receives neurotransmitters. Usually on dendrites.

What is "resting potential?"
 

Resting Potential is when a neuron isn't being  stimulated by other neurons' neurotransmitters
 

When is a neuron at "Graded Potential?"
 

When is a neuron at "Action Potential?"
 

A neuron is at action potential when it is stimulated enough that it fires neurotransmitters at other neurons.
 

What is reuptake?
 

Reuptake is when a neurotransmitter is taken back into the axon terminal that released it. 
 

When reuptake is blocked, the neurotransmitter stays in the synapse and keeps stimulating the next neuron.
 

What is one function that acetylcholine controls in the brain?
 

In the brain, Acetylcholine helps control memory.
