allometry
Allometry is a nonlinear relationship of different measurements of organisms across a range of sizes. Many measurements follow a power relation, in which larger values of one measurement are related to a logarithm or exponent of another measurement.
Brain-body allometry revisited across mammals
Reviewing a 2021 paper in Science Advances by J. B. Smaers and coworkers, which looks at brain-body allometry across mammals.
