How do we deal with the biological state “I’m thinking”? Can perception, recognition, decision, planning, and other subjective states be explained by objective relationships? I stand on the assumption that all these phenomena can be interpreted at the level of neural function. Based on this viewpoint, I am exploring the neural circuitries underlying animal behaviors.
