Acquired immobility response in weaver mutant mice.
Weaver mutant mice, contrary to normal littermate controls, did not acquire the immobility response in a forced swimming task. In regard to swimming performance, the weaver mutants swam with less ability but with more vigor than normal mice. Results are discussed in terms of the role of the cerebellum in swimming behavior.
