HEARING RESEARCH文献大全abstract::The avian auditory papilla provides an interesting object on which to study efferent influences, because whereas a significant population of hair cells in birds is not afferently innervated, all hair cells are efferently innervated (Fischer, 1992, 1994a, b). Previous studies in mammals using contralateral sound to sti...

An important transcription factor involved in the signaling and adaptation to hypoxia/ischemia is the hypoxia-inducible factor-1 (HIF-1). To study HIF-1 expression we used an in vitro hypoxia model of explant and dissociated cultures o...
