This is a list of animals by number of neurons in their brain. These numbers are estimations derived by multiplying the density of neurons in a particular animal by the average weight or mass of the animal's brain
Overview
Neurons are the cells in the brain which transmit information to and from body parts. In the simplest organisms, they act only to drive the organism to respond to certain stimuli. In higher organisms, reasoning abilities come into play and we can see animals working collectively to achieve a similar goal. Not all animals have neurons; Trichoplax and sponges lack nerve cells altogether.
