Figure 7. — Decoding spirals. A, Spiral sense exemplars. B, Multiscale PCM's spatial pattern response output difference between spiral sense for the six different spatial frequency channels (SFC): 2.50, 1.25, 0.8250, 0.6250, 0.5000, and 0.4250 cycles/°. C, Mean activation as a function of polar angle for the different spatial frequency channels. The x-axis is a double wedge region with a width of 90° that shifts stepwise in 22.5° steps (diagrammatically shown below the axis). The y-axis is the mean layer activation within the defined region for the spatial frequency channel. D, Spatial difference between senses after combining the six multiscale PCM spatial frequency channels. E, Mean activation as a function of polar angle. F, Mean activation as a function of polar angle for four radiuses: the inner edge (circles), the outer edge (diamonds), and two radiuses inside the stimulus (squares and crosses).
