Figure 1: Microdissection of olfactory bulb slices. Rat Olfactory bulb slices were separated by free-hand microdissection using a dissection microscope equipped with a cold stage and used immediately for the release experiments. (a) Complete 400 μm thick olfactory bulb slice, as seen under the dissection microscope. (b) Micro dissected layers of the bulb. A: Olfactory nerve layer. B: Glomerular layer. C: External plexiform layer (EPL). D: Mitral cell layer. E: Granule cell layer. F: Ependyma layer.
