Title: Stream of consciousness
Description: This image comes from a 70 nm thin section from cultured mouse neurons magnified 15000 times. The sample was fixed by high pressure freezing and stained by freeze substitution using a solution of Osmium tetroxide and Uranyl acetate in acetone. No post staining of the sections was performed before the imaging. This kind of staining technique allows to appreciate the beautiful cytoskeleton of this cultured neuron that, in this detail, seems to assume the features of a river placidly flowing downstream, to the infinite sea of consciousness.
