Dynamic simulations

Definition

Dynamic simulations are computational models that mimic the behavior of biological systems over time, allowing for the exploration of how various components interact within those systems. These simulations are crucial for understanding complex processes such as signaling cascades and cross-talk, as they provide insights into the temporal changes and responses that occur in biological networks. By simulating the dynamics of these interactions, researchers can predict outcomes, test hypotheses, and gain a deeper understanding of cellular mechanisms.
