Abstract
A persistent blink reflex to light (BRL) was observed in a patient who became comatose after a cardiac arrest. Postmortem examination revealed severe hypoxic ganglion cell necrosis of the cerebral and cerebellar cortex, the basal ganglia, the hypothalamus, nuclei in the brain stem, and the superior colliculi. The pretectum was unaffected. These findings suggest that the afferent fibers of the BRL enter the brain stem not in the superior colliculus, but in the pretectum.
摘要
在一名心脏骤停后昏迷的患者中观察到持续的对光眨眼反射（BRL）。尸检显示大脑和小脑皮质、基底神经节、下丘脑、脑干核以及上丘存在严重的缺氧性神经节细胞坏死。顶盖前区未受影响。这些发现表明，BRL的传入纤维不是进入上丘，而是进入顶盖前区从而进入脑干。
