Synapses act as gatekeepers in the nervous system. What does this mean?

Every stimuli that generates an action potential is sent to the brain. The gatekeeping of the synapses occurs only when the body is unconscious and resting.

The synapses guard against unwanted pain signals. The synapses prevent very strong stimuli from being passed along to the next neuron.

The synapses sort through the action potentials, organizing the signals by their types and their location of origin.

Not every action potential is transmitted to the next neuron. Stimuli must be strong enough or come from enough areas to be passed on.
