Voytek et al provide more evidence that oscillatory dynamics play a critical role in neural communication and cognitive control.  As humans performed tasks that required greater abstraction, there was an increase in theta synchrony between anterior and posterior frontal cortex.  This may allow more anterior frontal cortex is communicate the higher level goals to motor cortex.
