Abstract
The cerebellum is a structure of the central nervous system involved in balance, motor coordination, and voluntary movements. The elementary circuit implicated in the control of locomotion involves Purkinje cells, which receive excitatory inputs from parallel and climbing fibers, and are regulated by cerebellar interneurons. In mice as in human, the cerebellar cortex completes its development mainly after birth with the migration, differentiation, and synaptogenesis of granule cells. These cellular events are under the control of numerous extracellular matrix molecules including pleiotrophin (PTN). This cytokine has been shown to regulate the morphogenesis of Purkinje cells ex vivo and in vivo via its receptor PTPζ. Since Purkinje cells are the unique output of the cerebellar cortex, we explored the consequences of their PTN-induced atrophy on the function of the cerebellar neuronal circuit in mice. Behavioral experiments revealed that, despite a normal overall development, PTN-treated mice present a delay in the maturation of their flexion reflex. Moreover, patch clamp recording of Purkinje cells revealed a significant increase in the frequency of spontaneous excitatory postsynaptic currents in PTN-treated mice, associated with a decrease of climbing fiber innervations and an abnormal perisomatic localization of the parallel fiber contacts. At adulthood, PTN-treated mice exhibit coordination impairment on the rotarod test associated with an alteration of the synchronization gait. Altogether these histological, electrophysiological, and behavior data reveal that an early ECM disruption of PTN composition induces short- and long-term defaults in the establishment of proper functional cerebellar circuit.

Abstract
The present study evaluated the effects of the principal active component of marijuana (delta 9 THC) on motor abilities and motor learning in mice with cerebellar dysfunction. For this purpose, spontaneous locomotor activity, equilibrium abilities, muscular tone, motor coordination and motor learning were investigated in Lurcher mutant and non-mutant B6/CBA mice 20 min after i.p. administration of 4 or 8 mg kg(-1) of delta 9 tetra hydro cannabinol (delta 9 THC). The performances were compared to those obtained by Lurcher and non-mutant mice injected with vehicle (Tween 80). The results showed that at the dose of 4 mg kg(-1) but not at the dose of 8 mg kg(-1), the cannabinoid (CB) substance reduced deficits in motor coordination, equilibrium and muscular tone and facilitated motor learning in Lurcher mice. On the other hand, only a muscular strength decrease was observed in control B6/CBA mice injected with the dose of 8 mg kg(-1) of delta 9 THC. These results suggested that cannabinoid derivative could represent a new field of investigation concerning the treatment of cerebellar ataxic syndrome in humans.

Abstract
Heterozygous cerebellar mutant (Rora(+)/Rora(sg)) mice and control (Rora(+)/Rora(+)) mice of the same C57Bl6/J strain, 3-24 months old, were subjected to motor training on a rotorod for 10 days. Falling latency and percentage of time spent walking were measured. A good correlation was found between falling latency and walking time: the mice which maintained equilibrium for a long time were those which were walking, and the mice which fell early were those which were gripping suggesting that walking is obviously the most adapted strategy to keep balance on the rotorod. In Rora(+)/Rora(+) mice, scores before training were altered very precociously (from 6 months of age). Moreover, scores of Rora(+)/Rora(sg) mice were lower than those of Rora(+)/Rora(+) mice from the age of 3 months, while neuronal number in the cerebellar cortex of these mutants was quite normal and similar to that of Rora(+)/Rora(+) mice. This suggests that the motor skill disability would be due to fine structural and/or biochemical changes preceding neuronal death. Such subtle changes would begin several months earlier in Rora(+)/Rora(sg) than in Rora(+)/Rora(+) mice. Training on the rotorod resulted in increased scores in both genotypes at all ages. Motor learning abilities were therefore preserved in animals with a moderate neuronal loss in the cerebellum. It may be that motor learning is partly compensated by the striatum, which is known to play a major role in learning of motor skills.

Abstract
Motor learning abilities on the rotorod and motor skills (muscular strength, motor coordination, static and dynamic equilibrium) were investigated in three-, nine-, 15- and 21-month-old Lurcher and control mice. Animals were subjected to motor training on the rotorod before being subjected to motor skills tests. The results showed that control mice exhibited decrease of muscular strength and specific equilibrium impairments in static conditions with age, but were still able to learn the motor task on the rotorod even in old age. These results suggest that, in control mice, efficiency of the reactive mechanisms, which are sustained by the lower transcerebellar loop (cerebello-rubro-olivo-cerebellar loop), decreased with age, while the efficiency of the proactive adjustments, which are sustained by the upper transcerebellar loop (cerebello-thalamo-cortico-ponto-cerebellar loop), did not. In spite of their motor deficits, Lurcher mutants were able to learn the motor task at three months, but exhibited severe motor learning deficits as soon as nine months. Such a deficit seems to be associated with dynamic equilibrium impairments, which also appeared at nine months in these mutants. By two months of age, degeneration of the cerebellar cortex and the olivocerebellar pathway in Lurcher mice has disrupted both lower and upper transcerebellar loops. Disruption of the lower loop could well explain precocious static equilibrium deficits. However, in spite of disruption of the upper loop, motor learning and dynamic equilibrium were preserved in young mutant mice, suggesting that either deep cerebellar nuclei and/or other motor structures involved in proactive mechanisms needed to maintain dynamic equilibrium and to learn motor tasks, such as the striatopallidal system, are sufficient. The fact that, in Lurcher mutant mice, motor learning decreased by the age of nine months suggests that the above-mentioned structures are less efficient, likely due to degeneration resulting from precocious and focused neurodegeneration of the cerebellar cortex. From this behavioral approach of motor skills and motor learning during aging in Lurcher mutant mice, we postulated the differential involvement of two transcerebellar systems in equilibrium maintenance and motor learning. Moreover, in these mutants, we showed that motor learning abilities decreased with age, suggesting that the precocious degeneration of the cerebellar Purkinje cells had long-term effects on motor structures which are not primarily affected. Thus, from these results, Lurcher mutant mice therefore appear to be a good model to study the pathological evolution of progressive neurodegeneration in the central nervous system during aging.

Abstract
An unsteady platform test is presented in which mice must remain still on a narrow surface in order to prevent a fall. The mouse spontaneous mutation, Lurcher, causing cerebellar cortical degeneration, was evaluated on the unsteady platform, requiring balance in a stable body position (static equilibrium), as opposed to the stationary beam test, in which the animals are free to move on a larger surface (dynamic equilibrium). Lurcher mutants spent less time and had a higher number of slips than controls on the unsteady platform. In contrast, Lurcher mutants did not differ from controls for latencies before falling and distance travelled on the stationary beam. These results are discussed in terms of the possible involvement of two cerebellar circuits in motor control.

Abstract
Administration of harmaline to the rat, which activates synchronously and rhythmically the olivary neurons and the olivocerebellar pathway, elicits visuo-motor, spatial learning and spatial memory deficiencies which are dose-dependent. Since activation and lesion of the olivocerebellar pathway have similar effects, it is concluded that normal functioning of this pathway is required for spatial learning achievement.

Abstract
Lurcher mutant mice (+/Lc) exhibit a massive loss of neurons in the cerebellar cortex and the inferior olivary nucleus, while deep cerebellar nuclei are essentially intact. To discriminate the relative participation of the cerebellar cortex and deep structures in learning and memory, 3 to 6-month-old +/Lc mice were subjected to a spatial learning task derived from the Morris water escape. They were able to learn to escape as well as their strain-matched controls (+/+). Seven days later, their scores showed that they had memorized the spatial environment but not as accurately as +/+ mice. Cerebellectomy before training did not significantly alter the escape learning capabilities of either group, whereas cerebellectomy performed after learning completely abolished retention in +/+, as well as in +/Lc, mice. These results suggest that the cerebellum, although not necessary for learning a spatial task, plays a crucial role in its retention, and that the storing structure of spatial information differs in +/+ and +/Lc mice.
