A dog's brain functions similarly to a human brain, with regions responsible for different activities like sensory perception, movement, learning, and memory. In a dog's brain, you would find structures such as the cerebral cortex, which processes information, the cerebellum, responsible for coordination and balance, and the hippocampus, involved in memory formation. Overall, a dog's brain enables them to perceive the world around them, learn from experiences, and interact with their environment.
