CUPCAKE

STIMULI

Add vignette condition. Is the neural basis for the coarse-scale orientation bias a by-product of stimulus properties, like edge or vignette?

isolate every other ring from aperture

make hard edge

1-grating for isolated positions

radial eccentricity scaled vignette

vignette with hard edge

vignette hooray (added as 'vignette' case to rd_aperture in google drive)
