Discriminative stimulus effects refer to the ability of a drug, upon administration, to serve as a cue that can predict environmental contingencies, e.g., which of two levers will result in the delivery of a reward if pressed. Discriminative stimulus effects can therefore be thought of as the...
Quorum sensing is a phenomenon whereby bacteria use small signaling molecules for cell-to-cell communication in response to cell population densities and environmental stresses such as food processing and storage. Virulence characteristics of pathogenic microorganisms such as antibiotic production, biofilm ...
