The brain of the insect resides in the head, either dorsally or backward. This consists of three lobes:
protocerebrum,deutocerebrum,tritocerebrum.Such lobes are ganglia fused neuron clusters that store sensory information. The growing lobe regulates the different functions or tasks. Neurons range in an amount within the brains of insects. There are 100,000 neurons in the common fruit fly, while one honeybee has 1 million neurons. This contrasts with about 86 billion human brain neurons.
