Fig. 7. Recording the R1 component of the blink reflex (BR). To the left: recordings of the R1 component of the BR from one patient. In this patient a train of four stimuli elicited the responses, whereas trains consisting of one, two, or three stimuli did not. Each trace represents the average of two responses. To the right: recordings of the R1 component of the BR from another patient showing the high reproducibility of the responses. Each trace represents the average of two responses. The last trace represents the superposition of the first six. Adapted from Deletis V, et al., Muscle Nerve 2009;39:642-646, with permission from Wiley Periodicals, Inc.25
