In the cochlea, mammals maintain a uniquely high endolymphatic potential (EP), which is not observed in other vertebrate groups. However, a high [K+] is always present in the inner ear endolymph. Here, we show that Kir4.1, which is required in the mammalian stria vascularis to generate the highly positive EP, is absent in the functionally equivalent avian(More)
Mechanoelectrical transduction in the vertebrate inner ear is a highly conserved mechanism that is dependent on K+ influx into hair cells. Here, we investigated the molecular underpinnings of subsequent K+ recycling in the chicken basilar papilla and compared them with those in the mammalian auditory sensory epithelium. As in mammals, the avian auditory(More)
