Nerve impulses

Neurons communicate by receiving and transmitting these impulses.

1

Process of information exchange

The axon terminal's and the presynaptic neuron are stimulated. The terminals contain synaptic vesicles, which empty neurotransmitters into the synapse between the neurons. Neurotransmitters activate the postsynaptic neuron, changing it's voltage. Once the excitation of threshold is reached, the action potential begins, and a neuron fires.

2

Synapse

The small gap between neurons where information is exchanged.

3

Synaptic vesicles

Places where neurotransmitters are stored until release into the synapse.

4

Neurotransmitters

Chemicals that stimulate your own so they can communicate.

5

Excitatory neurotransmitter

Make neurons more likely to fire.

6

Inhibitory neurotransmitter

Make neurons less likely to fire.

7

Excitation threshold

The voltage difference necessary to destabilize a neuron, causing an action potential to occur.

8

Action potential

The brief change and electrical charge the destabilize is a neuron. The action potential stimulates the axon terminal, restarting the process.
