The brains of shrimps and insects are more alike than we thought

New research shows that crustaceans such as shrimps, lobsters and crabs have more in common with their insect relatives than previously thought — when it comes to the structure of their brains.

Both insects and crustaceans possess mushroom-shaped brain structures known in insects to be required for learning, memory and possibly negotiating complex, three-dimensional environments, according to the study, led by University of Arizona neuroscientist Nicholas Strausfeld.

The research, published in the open-access journal eLife, challenges a widely held belief in the scientific community that these brain structures — called “mushroom bodies” — are conspicuously absent from crustacean brains.- SCIENCEDAILY
