Stapedial reflex in neonates. 1978

R W Keith, and R J Bench

This paper considers the effect of behavioral responses on stapedial reflex data of neonates. Twenty clinically normal neonates were tested to determine whether repeated acoustic stimulation would habituate the behavioral response, leaving only the stapedial reflex for observation. The results failed to show systematic decline of behavioral response over trials. Stapedial reflex testing indicates a positive response for less than 5% of stimulus presentation. The results are discussed in terms of possible explanation for the apparently low incidence of stapedial reflex in a normal neonatal population.

UI	MeSH Term	Description	Entries
D007231	Infant, Newborn	An infant during the first 28 days after birth.	Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D009132	Muscles	Contractile tissue that produces movement in animals.	Muscle Tissue,Muscle,Muscle Tissues,Tissue, Muscle,Tissues, Muscle
D012022	Reflex, Acoustic	Intra-aural contraction of tensor tympani and stapedius in response to sound.	Acoustic Reflex
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000161	Acoustic Stimulation	Use of sound to elicit a response in the nervous system.	Auditory Stimulation,Stimulation, Acoustic,Stimulation, Auditory
D013198	Stapedius	A tiny muscle that arises from the posterior wall of the TYMPANIC CAVITY of MIDDLE EAR with its tendon inserted onto the neck of the STAPES. Stapedius pulls the stapes posteriorly and controls its movement.
