Insect brains, like the honey bee brain shown here, are very different in shape from human brains. Despite that, bee and human brains have a lot in common, including many of the genes and neurochemicals they rely on in order to function. The bright green dye marks the presence of tyrosine hydroxylase, a gene that allows the brain to produce dopamine. Dopamine is involved in many important functions, such as the ability to experience pleasure.
