A-D, three sequences during 38 cycles of driving at one 1500 ms phrase each 5 s, showing alternating runs of SIRs (phrases 3, 4, 11-27, 30-38), S2Rs (phrases 7-10, 27-28), skipped responses (phrases 12, 22, 37, etc.) and spontaneous flashes (SP). E-F, 9 cycles of driving at 1/10 s, during which there was first spontaneous flashing (1-4) then regular SIRs (5-9). Except for indicated omissions, record A-F is continuous. G-J, continuous driving sequence from different part of record of same female, showing SIRs at one phrase per 5 s (G), followed by single and paired spontaneous flashes (H) and a mixture of SIRs and S2Rs during stimulation at 10 s intervals (J). Durations of some spontaneous interflashes given in seconds with decimals. Female 62; 22°; signal duration 2 ms. Latency values in parentheses interpreted as spurious or (E3) Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Bio
