No one really wants to go back to that time (whenever it was; pick a random historical period over a hundred years ago), except maybe for some men who are really misogynistic.
We could have made up such a pattern, but we wanted the pattern to have exactly the same statistics as the Poisson distractor part (to make the pattern detection harder), so we preferred to randomly pick a 50 ms period of the original Poisson spike trains and to 'copy-paste' it (see below).
