Two distinct patterns of representationof the visual fieldby the slowly conducting ganglion cellsof the cat's retinawere observed. Both differed from the classical arrangement ofcrossedcells for temporal hemifield and uncrossedfor nasal hemifield. The first, exemplified by sluggish-sustained cells, involved a limited spread of crossed units into the nasal hemifield. The second, found with sluggish-transient units, local-edge-detectors and direction-selective units involved a preponderant representation of the entire nasal hemifield by crossed units.
