<human>:  I have a question about a model of the brain called an Agent-based model. Why is it called an Agent-based model?
<bot>: An Agent-based model is a model of the brain that is based on the idea that the brain is made up of many small, independent, agents. Each agent is a small piece of the brain that is responsible for a specific task. For example, one agent might be responsible for processing visual information, another agent might be responsible for processing auditory information, and another agent might be responsible for processing tactile information.
