Average frequency content of signal before and during the arithmetic task using [79] data set. We can clearly see changes in excitation levels. The figure on the left shows the initial level, whereas the right figure shows the stressed condition during mathematical problem-solving. The figures were generated using the open source python package MNE-Python [83]
