Fig. 1. Different size tuning of three types of neurons in the visual cortex.

Fig. 1

a) Top: Schematic of the experimental setup. Center: Response of example unit to visual stimuli of three different sizes (top row: Raster plot; bottom row: PSTH). Shaded area represents period of stimulus presentation. Bottom: Average size tuning curve of 53 peak-aligned and normalized single units (6 animals, 11 recording sessions). Gray triangles and a dashed line: baseline firing rate. Inset: Average of the normalized but not peak-aligned 53 size tuning curves.

b) Top left: Schematic of the experimental setup. Top right: td-Tomato expressing PV (red) with attached Alexafluor 488 filled recording pipette (green). Center: Response of PV to visual stimuli of three different sizes (top row: Raster plot; bottom row: PSTH). Bottom: Average size tuning curve (n = 11 peak-aligned and normalized size tuning curves; 3 animals). Inset: Average of the normalized but not peak-aligned 11 size tuning curves.

c) As in (b) but for SOMs (n=7; 4 animals).

d)– f) Distribution of SIs (left panels) and of preferred stimulus sizes (right panels) for single units (d), PVs (e) and SOMs (f). The SOM and PV data are superimposed onto the single unit data (gray, from (e)) for comparisons. All error bars are s.e.m.
