In laboratory studies, house mice can navigate mazes and solve multi-step puzzles, demonstrating cognitive abilities comparable to rats in learning and memory tasks.
- 05
The olfactory bulb in mice comprises roughly 25 percent of their total brain volume, compared to just 5 percent in humans, enabling extraordinarily sensitive smell detection.
