Fig. 1From: A contrastive analysis of laser heating between the human and guinea pig cochlea by numerical simulationsIllustration of the four-layer cylindrical model for simulations in XY plane. Laser light is delivered by an optical fiber which is placed 200 μm far from the osseous spiral lamina. Light passes through the perylimph and the osseous spiral lamina, and reaches the nerve layer. Characters A and O mark two representative sites where the temperature rise vs, time is presented below. The diameter of the cochlear shell is 6 mm for humans and 3 mm for guinea pigs. The diameter of the cochlear nerve core is 2 mm for humans and 0.8 mm for guinea pigsBack to article page
