Abstract
• The electrically elicited blink reflex was tested in 30 full-term neonates. Of the two distinctly separate responses, early component R₁ and late component R₂, R¹ was recorded in all but three infants. Its latency, 12.1 ± 1.0 msec (mean ± SD), was significantly greater than that in adults (10.6 ± 0.8 msec) despite a considerably shorter length of the reflex arc in infants. Unlike the response in adults, R₂ was elicited in only 20 of 30 infants, mostly on the side ipsilateral to the stimulus. The reduction of reflex excitability of R₂ in neonates must occur primarily at the level of interneurons since oligosynaptic R₁ was elicited with ease whereas polysynaptic R₂ was not.
