Simulation of a hypercolumn population raster in the presence of correlations.
Spiking responses of 360 cells coding for an external stimulus during a single trial are shown. Every line shows the spike-times of a single cell. The cells are arranged according to their preferred directions. Spike times are distributed as defined in the section ‘effect of correlations on tWTA accuracy’, see equation (34), with and . For the correlated part: (a) , ; (b) , . The dashed line shows .
