Identification of retinal ganglion cells and their projections involved in central transmission of information about upward and downward image motion.

ganglion cell :  12種類以上

direction-selective ganglion cell : 2種類（方向選択性：特定の方向に物が動いたときに反応する神経節細胞）

１．ON DS ganglion cells

→明るい物体が、ゆっくり動いたときに反応。

3 subtypes : upward, downward, or temporal-to-nasal motion in the visual field

２．ON-OFF DS ganglion cells

→明るい物体、または暗い物体が、ゆっくりまたは素早く動いたときに反応する。

4 subtypes : upward, downward, temporal-to-nasal, and nasal-to-temporal motion in the visual field
