How is the lobster's nervous system structured, relying on clusters rather than a centralized brain?

Answer

Fifteen scattered nerve clusters called ganglia

The internal mechanics of the lobster's nervous system demonstrate a decentralized processing architecture when compared to vertebrates. Lobsters do not develop a complex, centralized brain structure comparable to that found in mammals. Instead, their sensory processing and motor control are managed by approximately fifteen distinct, scattered nerve clusters distributed throughout the length of their body. Although there is a main nerve cluster situated near the head region that handles primary stimulus processing, the overall system relies on these numerous ganglia to coordinate responses and interpret environmental inputs across their segmented body plan.
