Quick Answer. Voltaire wrote Candide as a satire of the then-prevalent philosophical optimism advanced by Gottfried Wilhelm Leibniz. Voltaire, moved by contemporary events like the Seven Years' War and the 1755 Lisbon earthquake, felt that optimism was a naive way of viewing the world.
Neurons carry impulses from one place to another, around the many parts of the nervous system. They connect receptors to the central nervous system and also connect one part of the nervous system to another, for example in the brain and spinal cord.
Nerve impulses travel from neuron to neuron via neurotransmitters that are released into the synapse by the sending neuron. The neurotransmitter binds to a receptor on the recâ¦eiving neuron. When enough receptors are triggered, an action potential is initiated on the receiving neuron. Sujey Leon Hernandez.
