Fig. 10. Examples of reconstructions of random EOD amplitude modulations presented with either global or local stimulus geometry. Gray lines, Stimulus waveforms; variations in p-p EOD amplitude were measured within the RF center of the cell.Black lines, Reconstruction waveforms. Vertical lines, Times of spike occurrence. Bottom insets, Optimal filters; alignment to individual spike times is indicated by the vertical dotted line. A1, A2, Global and local stimulation, respectively, of a low-frequency E cell.B1, B2, Global and local stimulation, respectively, of a medium-frequency I cell. C1, C2, Global and local stimulation, respectively, of a high-frequency NB E cell.
