New insights into aging and learning
Bochum scientists have found that elderly - as compared to young - people show an increased excitability of the brain area that is responsible for processing the sense of touch in the hands (February 2012).
Scientists around Martin Tegenthoff (BFNL Sequence Learning, Bergmannsheil University Hospital) and Hubert Dinse (BFNL State Dependencies of Learning, BFNL Sequence Learning, Ruhr-Universität Bochum) report in the prestigious journal "Journal of Neuroscience," that such a "disinhibition" is associated with a better tactile sense in younger people and a declined tactile sense in the elderly. Thus, age-related changes are based on different mechanisms than those occuring during learning.
