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.
They are transmitted between neurons at a synapse, into neurons at a dendrite, and along neuro â¦ ns at the axon. Transmission at the synapse is via neurotransmitters released from the end of one neuron into the synapse, where they diffuse quickly over to the next neuron, usually to a dendrite or dendritic spine.he action of a neurotransmitter on a neuron is to open ion pores which allow Sodium ions to enter the neuron. The action along an axon of a neuron is an interchange of Sodium and Potassium ions, which propagates the impulse via the action potential.
