  1. This table shows the direction of change in MEG outcome measures for human MCI and simulated early AD-like or its opposite (contrast) scenarios. Neuronal activity (that is spike density of pyramidal neurons) can only be assessed in model data and show an increase in AD-like scenarios mainly. Of note, the interpretation of the direction (up/down) of parameter modification is intuitive, such that “up” of means hyperexcitability (which is actually derived by lowering the threshold) or stronger coupling.
