This study compared the results of reflex modification (RM)--an objective technique for assessing brainstem sensorineural processing--with those of auditory brainstem response (ABR) for a group of high-risk infants at comparable postconceptional ages. For the RM procedure, an eyeblink-eliciting tap to the glabella was presented either alone or accompanied by a brief 90dB SPL tone. 37 high-risk infants were tested with both RM and ABR at a mean postconceptional age of 37.3 weeks. Seven had an increased brainstem conduction time ('failed ABR') and eight did not exhibit significant reflex augmentation ('failed RM'), seven of whom also failed the ABR. These data provide evidence that sensory stimuli which affect the neural mechanisms responsible for the organization of the startle response and auditory processing share essential neural components.
本研究比较了反射修正（RM）——一种评估脑干感觉神经处理的客观技术——与听觉脑干反应（ABR）在一组孕龄相当的高危婴儿中的结果。对于RM程序，单独或伴随90dB声压级的简短纯音向眉间施加引起眨眼的轻拍。37名高危婴儿在平均孕龄37.3周时接受了RM和ABR测试。7名婴儿脑干传导时间延长（“ABR未通过”），8名婴儿未表现出明显的反射增强（“RM未通过”），其中7名婴儿ABR也未通过。这些数据提供了证据，表明影响负责惊吓反应和听觉处理组织的神经机制的感觉刺激共享基本的神经成分。
