**incoming processes is known as an afferent process, and outgoing processes are known as efferent processes. Virtually all of our thoughts, feelings, and actions can be brought down to a neuron"s reaction. The neuron: neurons vary widely in shape and size. Interneurons; exist directly inside the cns; complete all the translations/interpretations: communicates only with other neurons, approx. 10-100 billion: using their terminal endings, they communicate with the motor and sensory neurons, there was a debate about whether the brain was run on electrical currents or chemical reactions. The first discovery on the matter (base work on the electric theory) was founded by galvani (1737-98); an italian physicist: he took a frog and killed it, then hooked electric wires to the legs of the frog. Auto loewi wished to prove that the neurotal messaging was run by chemicals. He failed several times, not finding anything to prove the chemical theory.
