The clip opens with a brief synopsis of the process of neural transmission. The billions of neurons that compose our nervous system communicate with one another through the transmission of electrical signals or impulses. A synaptic gap separates the axon of the message-sending neuron from the dendrite of the receiving neuron. When impulses reach the axon terminal of the message-sending neuron, neurotransmitters are released and cross the synapse to receptor sites on the dendrites of the receiving neuron.
A computer generated-image displays the process. A green ball of light represents the electrical impulse. The impulse travels along the axon until it reaches the terminal and releases neurotransmitters represented by red balls of light. The neurotransmitters cross the synaptic gap and bind to receptor sites on the dendrites of the receiving neuron.
