Washington: A new research has shed light on the nature of human intelligence.
The most interesting finding from this study is that grey matter volume in the cerebellum predicts general intelligence. However, results differ for men and women, with men showing a stronger relationship between brain volume in the cerebellum and general intelligence.It has long been recognised that the cerebellum is involved in sensory-motor functions, including balance and timing of movements, but it is now believed that the cerebellum also plays an important role in higher-level cognitive abilities."General intelligence is correlated with many basic aspects of information processing efficiency which I believe depend upon the functioning of the cerebellum, including the speed and consistency of our perceptions and decisions, and the speed with which we learn new skills,” noted Michael Hogan, first author of the study."This is exciting research, as it suggests that there may be a backdoor route into maintaining higher cortical functions in old age, that is, through the sustained activation of cerebellar networks via novel sensory-motor and cognitive activities, all of which I believe the cerebellum seeks to regulate and automate, working in concert with the cortex,” added Hogan.The findings have been published in the journal of Elsevier`s Cortex.
