Cellular Model System Approach

The cellular model system approach focuses on how drugs affect the communication between cells. The primary way drugs can influence a person’s behavior is by altering the signaling between nerve cells. Because the human brain is made of millions of cells, this approach  uses a research strategy of using a simplified system as a model system. We will use slime mold as a model system, because this very simple organism uses chemical signals to communicate between cells, much as nerve cells do in the brain.
