In the heart of an ancient castle, a young fox named Reyna sat before a chessboard. She had always been curious about how her brain planned each move, and today she would finally understand. Her grandmother, a wise old vixen, watched from a velvet chair. "Your brain is the control center of your body," she said softly. "Every thought, every move, begins there." Reyna nodded, her eyes fixed on the pieces.
As Reyna reached for a knight, her grandmother explained, "Nerves send signals from your brain to your muscles, and back again." Reyna imagined tiny messengers racing through her body. She learned that each signal travels along a neuron, a special cell that carries information. "So when I move this piece," Reyna said, "my brain sends a signal to my paw." Her grandmother smiled. "Exactly, and your memory helps you recall past games."
