摘要: OBJECTIVE The cerebellum is a key structure involved in coordinated motor planning, cognition, learning and memory functions. This study presents permanent model of toxin produced cerebellar lesion characterized according to contemporary cognitive abnormalities. MATERIALS AND METHODS In this experimental study, slow administration quinolinic acid (QA, 5 µl 200 µmol, 1 µl/minute) the right hemisphere (lobule VI) caused noticeable disturbances along with cellular degeneration all treated animals. We assessed behavioral histopathological studies over ten weeks after QA treatment. data were analyzed ANOVA student's t test. RESULTS group showed marked deficits on rotating rod test (p=0.0001), locomotor asymmetry cylinder dysmetria beam balance abnormalities neuromuscular strength hang wire spatial Morris water maze (MWM, p=0.001) fear conditioned passive avoidance (p=0.01) ten-week period compared control Histopathological analysis loss Purkinje cells (p=0.001) granular cell density (p=0.0001) lesioned cerebellum. CONCLUSION Results present show that can remove numerous which respond hemispheric lobule VI thus provide potential for functional cell-based studies.
