The phase shift is ## controled by 'ph_shift' and 'ph_dev'. ## ## The interaction will involve setting up a temporal mask following ## spikes from i2 that will be used to modulate the conductance ## induced by spikes from i1. ## The parameter 'dt' controls the timing of the peak of the positive ## interaction, and 'masktype' determines the shape of the mask function. ## <mech> # Direction selective mechanism name ds02 type si_ds02 # Synaptic interaction dt 0.020 # (s) Peak interaction time masktype 2 # 1-sinusoid, 2-maxwell mask_amp 1.0 # [1.0 default] mask amplitude mask_comp prod # ['prod'] 'prod', 'prod1m'= product 1-mask ph_shift 90.0 # Target phase shift between cells, -180 to 180 [90.0] ph_dev 5.0 # Deviation around phase shift [Broken near 180] <> ## ## DS Inputs ## <input> type regular # pop_origin ex # Where it comes from receptor ex # Where it lands syn_int ds02 # Synaptic interaction ## ## This controls the distribution across the population of the ## inputs.
