    ..Because we studied only a small number of subjects, we cannot firmly conclude that caffeine reduces LTP in humans. The present results will, however, be helpful when considering further or new clinical uses of caffeine. ..

    ..This improvement coincided with increased error-sensitivity and was present in both groups of subjects, suggesting that control of error-sensitivity may be spared despite cerebellar damage. ..

    ..Furthermore, the N20-P25 was also potentiated after QPS at IPIs of 5, 30, 50 100 or 500 ms. In ME patients, the cascade for long-term depression-like effects may be impaired. The giant SEP was furthermore enhanced by QPS. ..

    ..Subclinical sensory disturbance or a decrease of motor unit numbers might be candidates for such peripheral factors contributing to tremor genesis in SBMA...

    ..The age of the participants significantly affected the LTP-like effect induced by QPS5, which suggests that brain plasticity decreases with age. ..
