Margaret Alice Kennard (September 25, 1899—December 12, 1975)[1] was a neurologist who principally studied the effects of neurological damage on primates. Her work led to the creation of the Kennard Principle, which posits a negative linear relationship between age of brain lesion and outcome expectancy.[1]

Schooling and studiesEdit

She earned a Rockefeller Traveling Fellowship for study in Western Europe from 1934 to 1936.[2] She also studied the effects of stimulants and cortical depressants on monkeys with brain damage.[2]

Kennard PrincipleEdit

The observation that young brains reorganize more effectively than adult brains was first articulated by Kennard in 1936. Consequently, the notion that how well a brain can reorganize itself after damage as a function of the developmental stage is now known as the "Kennard principle".[3] This research led to one of the earliest experimental evidence for age effects on neuroplasticity.

She worked closely with John Fulton in her famous infant brain studies.
