Abstract
The ontogeny of swimming ability was studied in normally fed and in chronically starved rats to assess the effect of early malnutrition on CNS development. Swimming tests were performed on adult and infant rats from 4–30 days old in an aquarium. Scoring according to position of the nose and movement of front legs. Maturation of swimming performance was delayed 2–3 days in the chronically starved rats as compared to controls. The high sensitivity of nervous tissue during critical periods of maturation and the relationship between malnutrition and the development of some patterns of movement during swimming are considered.
