Differently from the delta band, the theta band does not seem to have a clear behavior regarding frequency amplitude: there are certain channels (and even specific frequency regions) in which the task block amplitude is greater than the rest block amplitude and vice versa. Besides, the frequency response for both blocks is much more similar than to the delta band.   Electrodes F5 and FFC3 seem to present some interesting differences, though (the first one in particular). From about 5.5 Hz to about 7.5 Hz, F5 electrode shows greater frequency amplitude to the rest blocks. Task blocks show a similar response regarding the shape of the signal, but a smaller frequency amplitude. Something similar occurs to FFC3 electrode from about 6 Hz. Again, as in the delta band, both of these the  electrodes that have a more apparent difference in their signals are located in the left side of the scalp.
