The small space between the axon terminal of one neuron and the dendrites of other neurons.
Chemical messengers that allow neurons to communicate with other neurons across the synapse.
Areas on neurons that connect and respond to neurotransmitters.
The most common neurotransmitter, which is used in movement in the peripheral nervous system and related to attention and memory in the brain.
A special class of neurotransmitters that regulate the activity of neurons and systems in the brain.
The level or point at which a neuron fires, or a neural impulse is triggered.
The state in which a neuron is not firing or sending a neural impulse and when there is a negative electrical charge inside the neuron.
The state in which a neuron reaches its Threshold of Excitation and fires, or sends an electrical impulse down the axon.
