Systems Biology

Connect genes, cells, organs, and environments into one responsive system.

Follow the mechanism1 / 3

Many parts are connected. Genes, proteins, cells, and tissues influence one another, so a change in one node can travel through several linked pathways.

The signal is 67.6, coupling passes 38.9 into the output, and the network produces 24. Changing one node changes the system's response.

This is a small dynamical network, not a whole organism. Real systems add multiple timescales, nonlinear thresholds, spatial compartments, noise, and cross-talk between pathways.
