Mice (IMAGE) Proceedings of the National Academy of Sciences Caption Normal mice (left) shred a pressed cotton square and arrange the material to build a nest. Nesting behavior is impaired (center) following injection of alpha-synuclein fibrils into the striatum (the part of the brain where dopamine producing neurons project to), but this behavior is preserved in fibrilinjected mice co-treated with EHT and caffeine (right).
