The human, rabbit, and mouse databases were preprocessed with moderate combined filtering (i.e., range plus moving average filter), and the dog database was preprocessed with the combined filtering with a moving average filter threshold at 40%. ∗For the human database we excluded files “16773,” “19093” and also parts of “19088,” “18177” because of inaccurate annotations in large parts of the recordings. Abbreviations: p, the number of 5-min segments for humans, dogs, and rabbits and 3-min segments for mice; n, the number of animals.
