C. caud. | C. ceph. | Pol. diff. | C. caud. | C. ceph. | Pol. diff. | |
∆BR (%) | −16.2 ± 2.88 | −22.9 ± 2.5 | 6.7 ± 2.11* | −39.6 ± 2.9 | −42.1 ± 2.94 | 2.5 ± 1.75 |
∆HR (%) | −5.7 ± 0.55 | −3.4 ± 0.34 | −2.3 ± 0.46* | −8.7 ± 0.54 | −6.3 ± 0.41 | −2.4 ± 0.46* |
Responses observed with pulse widths 100 μs or shorter were similar to each other; responses with pulse widths 240 μs or longer were similar to each other. Therefore, pulse widths were categorized in one of 2 groups: either short (<=100 μs) or long (>= 240 μs).
