Electrophysiological and morphological comparisons of tonic and phasic retinal ganglion cells (RGCs)

Tonic RGCs Phasic RGCs Difference
Percentage of total 84 RGCs 28.6 (n = 24) 56.0 (n = 47) N/A
Erest (mV, mean ± SE) −64.9 ± 1.6 (n = 24) −67.4 ± 1.2 (n = 47) >0.05*
Rinput (GΩ, median) 0.56 (n = 18) 0.29 (n = 41) <0.01
Slope parameter (mean ± SE) 1.03 ± 0.14 (n = 20) 2.45 ± 0.34 (n = 30) N/A
Cm (pF, median) 10.6 (n = 24) 14.2 (n = 47) <0.05
Cross-sectional soma area (μm2, median) 218 (n = 23) 226 (n = 44) <0.05
  • Slope parameter is a parameter characterizing the shape of the sigmoid function fitted to the firing frequency–stimulus intensity (F–I) relation (see results for further explanation; cf. Fig. 4). Erest, resting membrane potential; Rinput, input resistance; Cm, membrane capacitance.

  • *P value obtained by unpairedt-test,

  • P values obtained by Wilcoxon/Kruskal-Wallis rank sum test.
