A team of researchers at the University of Illinois at Urbana-Champaign has found that when bees experience positive versus negative events, their brains process and remember the events differently. In their paper published in Proceedings of the Royal Society B, the group describes their study of bee brain processing and memory retention and what they found.

Scientists have known for a long time that vertebrates handle positive and negative events differently, storing and retrieving those memories in their brains differently, as well. In this effort, the researchers wanted to know if the same could be said of invertebrates such as the common honeybee. To find out, they exposed test bees to positive or negative events and then studied gene expression in a part of their brain known as the mushroom body—an area involved in processing sensory information, learning and memory.

More specifically, the researchers exposed the bees to positive experiences such as tending to their young or negative experiences such as dealing with a threat like an enemy or a predator. They then quickly froze the bees...
