Effects of hyperbilirubinemia on the hearing and vocal development in Gunn rats. 1982

M L Lenhardt

Jaundiced rats do not differ from normal rats in the development of frequency-specific startle responses to sound in spite of the auditory brainstem damage in the affected rats. Jaundiced rats do show a vocal motor abnormality. Behavioral auditory results support the concept of neural involvement in early vocal development; however, the site of involvement in hearing development is still ambiguous.

D006932	Hyperbilirubinemia	A condition characterized by an abnormal increase of BILIRUBIN in the blood, which may result in JAUNDICE. Bilirubin, a breakdown product of HEME, is normally excreted in the BILE or further catabolized before excretion in the urine.	Bilirubinemia,Bilirubinemias,Hyperbilirubinemias
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013216	Reflex, Startle	A complex involuntary response to an unexpected strong stimulus. The reaction involves physical movement away from the stimulus, MUSCLE CONTRACTION and limb flexion, BLINKING, and changes in HEART RATE, BLOOD PRESSURE, and RESPIRATION.
