DS_Post_Fac_T2   This elaboration of the DS_Post_Fac model has two temporal channels, one fast and one slow. Each channel has separate LGN and V1 units up to the final direction selective (DS) stage. The DS cells are created from pair-wise interactions of spiking inputs in the fast channel, and separate pairwise interactions from the slow channel. This model displays adaptive temporal integration as defined by Bair and Movshon (2004; McLelland et al., in preparation). See the description of DS_Post_Fac for an explanation of the pairwise interaction.
