| slow-conducting retinal ganglion cell | Fukuda-physiological (F-physio) | Further support for the three-group classification of ganglion cells was gained by physiological measurements of conduction velocities of ganglion cell axons. By recording axonal or cellular discharges in the retina values of 16.8 ± 1.5, 11.4 ± 1.0 and 6.3 ± 1.1 m/sec were obtained as the average velocities of the fast, intermediate and slow conducting axons. These groups are presumably the axons of L-, M- and S-cells, respectively. | partial correspondence | | Further support for the three-group classification of ganglion cells was gained by physiological measurements of conduction velocities of ganglion cell axons.

These groups are presumably the axons of L-, M- and S-cells, respectively. Furthermore, the sampling ratios of the L-, M- and S-type ganglion cells in the retinal recordings were 14, 39 and 48%. These figures reflect relative frequencies of histologically identified L-, M-, and S-cells (5, 30 and 65%) since in unit recordings large cells are over-represented and small cells under-represented. | Fukuda Y | Mihail Bota |
