A Appendix

A.1 Recurrent neural networks A.1.1 T ask structures One trial has T = 1400 time steps. All input conditions are trained simultaneously with equal probability to ensure a balanced training set (batch size = 400). In total, we defined P = 8 15 = 120 sampling locations. The sine wave generation network has 51 different input conditions (51 input levels). The respective local and global operative dimensions are defined as explained in section 2.2.1.
