Neurobehavioral evaluation of lurcher mutant mice during ontogeny

Abstract

Lurcher mutant mice were compared to normal littermate controls for body weight, body righting, negative geotropism, sensorimotor coordination (rotating grid, wire suspension, rotorod), and visuomotor coordination requiring swimming toward a pole during postnatal (P) days 0-30. Lurcher mutants had a lower body weight on P20-P30 and were slower before performing the complete body righting response on P13-P30. Because of postural instability during the negative geotropism test, lurcher mutants turned quicker up the slope than normal mice. The mutants fell sooner from the rotating grid on P11-P14, from the horizontal wire on P15-P16, and from the rotorod on P14-P30. Lurcher mutants were also slower before swimming to the pole or climbing to the top of the pole and were inferior in pole climbing height on P22-P30. These results indicate test-selective and time-selective neurobehavioral deficits during ontogeny in a spontaneous cerebellar mutant.
