Older adults exhibit greater brain activity than young adults in a selective inhibition task by bipedal and bimanual responses: an fNIRS study.

abstract：:Insulin-like growth factor (IGF)-I is essential for cerebellar granule neuron survival and a decline in IGF-I is implicated in various age-dependent processes. Here we show that IGF-I mRNA levels are decreased in the cerebellum of old rats compared with young rats and this was associated with increased cell death and ...
