Fig. 1 Optimal stimuli of neurons in the visual cortex (top 4 rows) and retina and LGN (bottom 2 rows). In the retina and LGN, cells are selective for only the sign of the stimulus, whether it is a dark or a light spot. In the cortex cells are selective for lines or edges. Individual cells are also selective for the width and orientation of their preferred stimulus type. Current Biology , R635-R637DOI: ( /S (01) )

Fig. 2 Organisation of inputs to lateral geniculate nucleus neurons. NOT, nucleus of the optic tract; BF, basal forebrain; BS, brainstem; RET, retina; PGN, perigeniculate nucleus; LGN, lateral geniculate nucleus. Redrawn from Figure 4 of Sherman and Guillery (1996). Current Biology , R635-R637DOI: ( /S (01) )

Fig. 3 Colour coding responses in the LGN. There are two classes of cells, based on the colour directions to which they respond best. (a,b) Cells in the P layers are excited by green and inhibited by red or vice versa. (c,d) Cells in the layers are excited by blue and inhibited by yellow or vice versa.
