Frequency Selectivity of Summating Potential Recorded From Scala Media of Cochlea in Guinea Pig the tegmentum vasculosum ( TV) sealed off scala media ( ScM) and separated it from scala vestibuli ( ScV). 耳蜗中阶记录总和电位(SP)频率选择性的实验观察血管盖封闭中阶(ScM)且将中阶与前庭阶分开;
Results The velocity of basilar membrane vibration elicited with tone was increased significantly when positive current was delivered to scala vestibuli and the velocity was decreased on the contrary. 结果当外加电流前庭阶极性为正,鼓阶极性为负时,可以看到基底膜振动速度显著增大,给相反极性电流时,基底膜振动速度减小。
Red blood cells in CSF can reach perilymphatic space through the cochlear canal, and widely distribute in scalae tympani and scala vestibuli after lateral ventricle puncture. 侧脑室穿刺后,脑脊液中红细胞可经耳蜗导管到达外淋巴,并随外淋巴纵行流动广泛分布到各转鼓阶和前庭阶。
