Scientists are trying to understand how the brain works when we think. They are creating computer models to mimic how our brains solve problems. These models are tested using brain and behavior experiments. While these models are not as smart as humans yet, they are getting closer. By studying how brain cells work together, researchers hope to explain how our brains create thoughts and behaviors. New technology allows scientists to study brain activity in animals and humans in more detail than ever before. By combining cognitive science, computational neuroscience, and artificial intelligence, researchers are making progress in understanding how our brains process information during thinking and decision-making tasks.
