Relationships Between Regional Cerebellar Volume and Sensorimotor and Cognitive Function in Young and Older Adults

Jessica A. Bernard, Rachael D. Seidler
2013 Cerebellum  
We found that older adults had smaller cerebellar volume than young adults; specifically, lobules in the anterior cerebellum were more impacted by age.  ...  Here, we investigated whether there are regional age differences in cerebellar volume in young and older adults, and whether these volumes explain, in part, individual differences in sensorimotor and cognitive  ...  In young adults, manual dexterity measured by performance on the grooved pegboard was negatively correlated with right Crus I volume.  ...

2019 Frontiers in Neurology  
Previous studies showed that children with Unilateral Cerebral Palsy (UCP) are impaired in implicit MI, as demonstrated by the performance of Hand Laterality Judgment tasks.  ...  A similar analysis revealed in the UCP group a positive correlation between a higher score in the mental chronometry task and bilateral activations of IPS, and to activation of contralesional, right PMd  ...  As control, a group of right handed (44) TD children matched by age (n = 12; 6 males; range 9-14 years old) were recruited.  ...
