对诱发性会聚性斜视猫的每只眼睛测量静止光栅和闪烁光栅检测的对比阈值。当测试模式静止时，偏离眼的表现不如非偏离眼。闪烁有助于减少两只猫眼睛之间的表现差异，但对第三只猫没有作用。这些结果表明，斜视弱视可能不是由单一类别的神经元缺陷引起的。在所有斜视猫中，与正常猫相比，非斜视眼的对比敏感度明显降低。这些行为发现，包括双侧发现的缺陷，与前一篇论文中对这些和其他斜视猫的皮层记录的结果非常吻合(7)。
Contrast thresholds for detection of stationary and flickering gratings were measured behaviorally for each eye of cats raised with induced convergent strabismus. The performance of the deviating eye was inferior to that of the nondeviating eye when test patterns were stationary. Flicker served to reduce the performance difference between the eyes in two cats but not in a third. These results suggest that strabismus amblyopia may not result from deficits within a single class of neurons. In all strabismic cats the contrast sensitivity of the nondeviating eye was significantly reduced relative to normal cats. These behavioral findings, including the deficits found bilaterally, correspond very well with results from cortical recordings from these and other strabismic cats presented in the preceding paper (7).
