A synapse in the thalamus creates a graded potential followed by an action potential in a secondary interneuron, which reaches the cerebral cortex 4. A primary interneuron forms an action potential and crosses to the opposite side of the brain 5. At a synapse, a presynaptic sensory neuron stimulates the postsynaptic interneuron to form a graded potential in its cell body 6. A stimulus from the brain causes graded potential and then an action potential to form in an upper motor neuron (which crosses back to the original side of the body) 7. In another synapse, neurotransmitter creates a graded potential, which triggers an action potential in the lower motor neuron 8. The lower motor neuron forms a neuromuscular synapse with the hand muscles, which causes the muscles to contract as he writes the letter
