Also, Jacques-Louis David was a 19th century painter who is considered to be the principal proponent of the Neoclassical style.
Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
