The level or point at which a neuron fires, or a neural impulse is triggered.
A special class of neurotransmitters that regulate the activity of neurons and systems in the brain.
The most common neurotransmitter, which is used in movement in the peripheral nervous system and related to attention and memory in the brain.
Areas on neurons that connect and respond to neurotransmitters.
Chemical messengers that allow neurons to communicate with other neurons across the synapse.
The small space between the axon terminal of one neuron and the dendrites of other neurons.
The state in which a neuron reaches its Threshold of Excitation and fires, or sends an electrical impulse down the axon.
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.
