AB  - How do distant brain areas communicate with each other? It is thought that neurons increase their impact on target groups through precise oscillatory synchronization. Long-range coherence modulation might represent a general mechanism for regulating the flow of information within the nervous system. To test this idea in human volunteers, Schoffelen et al. combined magneto-encephalography and electromyographic recordings during the performance of a basic reaction-time task, where the subjects implicitly learned the increasing or decreasing probability of a signal. The coherence of gamma-band (40 to 70 Hertz) oscillations between the motor cortex and the spinal cord did indeed make motor outputs more effective. J.-M. Schoffelen, R. Oostenveld, P.
