Effects of superior colliculus ablation on the air-righting reflex in the rat

Table 3 Comparison of movement aspects of air-righting reflex among control, unilaterally ablated, and bilaterally ablated rats

Animals	Gross action	Initial action			Righting sequence		Performance of lateral turn		Orientation		Landing posture
Animals	Lateral turn	Ventriflexion	Not obvious	Dorsiflexion	FQ/HQ	Simul.	Proper	Insufficient	Unchange	Change	Not tilted	Tilted
Control	68/68 100.0%	20/68 29.4%	48/68 70.6%	0/68 0.0%	56/68 82.4%	8/68 11.8%	62/68 91.2%	6/68 8.8%	50/68 73.5%	18/68 26.5%	55/68 80.9%	13/68 19.1%
Unilaterally ablated (N = 5)	164/171 95.9%	48/164 29.3%	103/164 62.8%	13/164 7.9%	65/164 39.6%	86/164^## 52.4%	119/164 72.6%	45/164^## 27.4%	61/164 37.2%	103/164^## 62.8%	93/164 56.7%	71/164^## 43.3%
Bilaterally ablated (N = 4)	110/117 94.0%	38/110 34.6%	52/110 47.3%	20/110^##,** 18.2%	21/110 19.1%	72/110^##,** 65.5%	68/110 61.8%	42/110^## 38.2%	53/110 48.2%	57/110^## 51.8%	63/110 57.3%	47/110^## 42.7%

The same format as Table 1. All variables significantly increased abnormalities by superior collicular lesions in comparison with control (P < 0.05). The initial action and righting sequence increased frequencies of occurrence, comparing unilaterally and bilaterally ablated animals. Chi-square test was performed for each variable; ^## P < 0.01 comparing control and ablated rats; **P < 0.01 comparing unilaterally and bilaterally lesioned animals
