Laser interference microscopy allowed Russian researchers to perform detailed analysis of a living neuron.

      The technique helped measure various parts of axon, the largest part of a neuron, thus providing researchers with a new powerful tool for studying living tissues and cells.

      Most currently existing techniques require fixation and dyeing of a biological object, which often deforms native structure of the object, as well as information about it. Moreover, in their work scientists used devices, created and built in Russia.

      Main principle of laser interference microscopy is measuring optical properties of objects and environment, as well as object’s height in measurement point. This technique allows accurate estimations of axon’s geometry and functional potential.
