- supplemental material - Supplemental Figure 1. Retinotopic map and absent orientation map measured with Kalatsky-Stryker imaging paradigm. a) Retinotopic map computed with phase responses to a drifting horizontal bar. The response phases to a downward moving bar has been subtracted from the phases of an upward moving bar, giving double the absolute phase of the bar position in a cycle. Color denotes phase, and intensity shows relative amplitude of modulation of response to the stimulus frequency. Scale bar is 1mm. b) Same as a) but for a vertical bar. c) Significantly different responses for retinotopy stimulation. All pixels are colored if the distribution of phases for each period of the stimulus is significantly different from uniform (p <_0.05 kolmogorov-smirnov="kolmogorov-smirnov" test.="test." colors="colors" indicate="indicate" a="a" relative="relative" phase.="phase." gray="gray" pixels="pixels" are="are" non-significant="non-significant" pixels.="pixels." white="white" denote="denote" areas="areas" of="of" high="high" blood="blood" vessels="vessels" or="or" low="low" out="out" focus="focus" standard="standard" deviation="deviation" and="and" excluded.="excluded." about="about" two-thirds="two-thirds" show="show" significant="significant" activity.="activity." d="d" significantly="significantly" different="different" responses="responses" for="for" orientation="orientation" stimulation.="stimulation." same="same" coloring="coloring" as="as" in="in" c="c" but="but" now="now" response="response" to="to" drifting="drifting" grating="grating" with="with" slowly="slowly" rotating="rotating" direction.="direction." few="few" activity.--="activity.--" end="end" desc="desc" supplementalfigure1.gif="supplementalfigure1.gif" _--="_--">
- supplemental material - Supplemental Figure 2. Ad-hoc method for removing blood vessel artifacts and regions out of focus. a) Standard deviation across stimuli averaged across six retinotopy stimuli for the same animal as in Figure 2. Pixels with higher standard deviations are lighter and those with lower standard deviations are darker. b) Histogram of average standard deviation across stimuli. Pixels with very low average standard deviations (values less than the left bar) tend to correspond to regions out of focus, and pixels with very high average standard deviations (values greater than the right bar) tend to correspond to large blood vessels. c) Pixels excluded from further analysis shown in white.
