the activity progression from the sensory-specific to supramodal regions during language processing (Marinkovic, 2004). The earliest activity was seen in the occipital area at ∼130 ms and it did not differ among the conditions. Lateral middle temporal area (LT) was engaged subsequently (at ∼250 ms) and showed less theta power to PW than to other conditions. Anteroventral and posterolateral prefrontal areas showed peak theta activity at ∼450 ms and were sensitive to both, the meaning and the task-imperative characteristics of the stimuli, with the strongest source power elicited by the AN. Theta power estimates to SW were weaker than to AN, but both meaningful conditions elicited stronger theta than PW, word-like, pronounceable letter strings without meaning. In the final stage, a strong theta generator was estimated to the hand motor area after ∼550 ms in the left hemisphere, during preparation and execution of responses to SW. A very similar activity specific to AN was observed in the motor area in the right hemisphere.
