The optic lobes are thought to be involved in visual processing (left). In this study, researchers found that guppies with larger optic lobes more quickly learned a visual discrimination task—identifying which color well contained food. The fish telencephalon is thought to be involved in spatial learning, memory, and inhibitory control (right). Here, the researchers found that a larger telencephalon might enhance the fish’s cognitive flexibility, allowing them to more quickly associate food with a new color after the researchers switched it.
