The nervous system of a fly, like that of Drosophila melanogaster, contains around 100,000 neurons and manages various behaviors. Neurons facilitate communication within the system and with other cells, enabling regulation of behaviors. The insect nervous system, having a brain, ventral nerve cord, and ganglia, can independently control movements and behaviors.
The nervous system of a common laboratory fly, Drosophila melanogaster, consists of around 100,000 neurons, similar in number to a lobster. In comparison, a mouse has 75 million neurons, an octopus has 300 million, and a human brain contains about 86 billion neurons.
Despite the varying neuron numbers, these animals' nervous systems control similar behaviors, from basic reflexes to complex activities like finding food and mating. Neurons play a crucial role in communication within the system and with other cells to regulate these behaviors.
The insect nervous system, including that of a fly, is relatively decentralized, comprising a brain, ventral nerve cord, and ganglia. These ganglia can autonomously manage movements and behaviors without direct input from the brain.
