WebBiologic Gradient Biologic gradient refers to the presence of a mono-tone (unidirectional) dose–response curve. We often expect such a monotonic relation to exist. For exam-ple, more smoking means more carcinogen exposure and more tissue damage, hence more carcinogenesis. Such an expectation is not always present, however.

The only way to change a coherence is to apply a pulse by phase ϕ. Therefore, we must know the coherence pathway we are interested in and we need to set the phases of the pulses and receiver accordingly.

WebBiological gradient (dose–response relationship): Greater exposure should generally lead to greater incidence of the effect.
