African grass rats (Arvicanthis niloticus) exposed to dim lights (DLD) for four weeks experienced, on average, a 30% decrease in the number of ‘dendritic spine’ connections in their brains, which are the tiny protrusions near the solid green line, a dendrite. These rats performed poorly on a maze-like task. Rats exposed to bright light (BLD), on the other hand, had many more of the dendritic connections and showed superior performance on the task.
