Environmental stimulus is suspected to play a role in both serotonin levels and neuron proliferation in the brain. To understand the relationship between environmental stimulus and serotonin levels Drosophila melanogaster were raised in two different environments, a stimulus rich and a stimulus deprived environment. The heads were isolated at different times and assayed for serotonin using an ELISA. The heads were also microscopically examined to determine if there were changes in neuroanatomical structures. It was observed that serotonin levels rose in flies that were reared in the stimulus rich environment. It was also observed that over time the flies reared in the stimulus rich environment had a change in character of the neuroanatomical structure, the protocerebral bridge.
