Kennard principle

the idea that brain damage sustained early in life is less debilitating than brain damage sustained later in life, presumably because of the enhanced ability of the younger brain to reorganize. This principle is not always confirmed. [Margaret Kennard (1899–1976), U.S. psychologist]

n. a type of involuntary movement caused by a rapid succession of alternate muscular contractions and relaxations. Although some forms of clonus, such as hiccups, are considered normal, most such movements are abnormal; for example, clonus occurs as part of a tonic–clonic seizure. More severe forms are associated with spinal cord damage, poisoning (e.g., from strychnine), or an infection (e.g., syphilis).
