- Title
Characteristics of Spontaneous Motor Activity in Neonatal Rats in a Novel Context.

- Abstract
We report here our studies of spontaneous motor activity in rat pups in the first two weeks of life. Increased levels of activity followed by decreases during testing could be seen by day 6 of life in rat pups, persisting to more adult animals. These behavioral changes resulted from simultaneous increases in the mobility not only of the forelimbs, but also the hindlimbs. Analysis of the dynamics of activity provides evidence that from day 6 of life, more than 84% of the variability in this parameter is described by two major components. The second component, explaining the elevated level of activity of rat pups in the first minute of the test and its subsequent decrease, is independent of the first component, which determines the baseline level of activity at 3-5 min of testing and is associated with the formation of the pyramidal tract.
