due to their non-additive interaction, the single input is not only integrated with others in the short-term timescales of 100-300 ms (alpha and theta frequencies) (as predicted by iit) but, at the same time, also virtually expanded in its temporal (and spatial) features; this is related to the longer timescales (delta and slower frequencies) that are carried over from pre-stimulus to stimulus-related activity. |
