Effects of cerebral venous congestion on ABR thresholds and GPIAS values in rats. a Schematic diagram of the experimental design. Behavioral tests were performed at 0 d, 7 d, 14 d, 1 M, and 3 M after JVL. The color code (yellow, 0 d; green, 7 d; blue, 14 d; brown, 1 M; red, 3 M) is used for all results. b-e Representative ABR traces (b) as well as ABR thresholds (c), wave I amplitude (d), and wave II latency (e) (presented as line graphs) in response to clicks and to 4, 8, 16, and 32 kHz tones (n = 10). f Percent of GPIAS at 4, 8, 12, and 16 kHz (n = 6). All data are shown as the mean ± SD. Statistical significance was calculated using a two-tailed unpaired Student’s t test. Dots depict individual samples. ns, not significance; *p < 0.05; **p < 0.01; ***p < 0.001
