Аннотация:The presented modification of the method of local optical tomography makes it possible to studythe dynamic processes of subcellular structures of native nerve cells. The advantage of this approach is that itis possible to analyze the dynamics of the distribution of neuron structures at a point or area of interest insidethe cell without performing a complete reconstruction of the cell image. It has been proved that it becomespossible to determine the dimensions, the cell area of interest, and the coordinates of subcellular structuresfor further study of their dynamics. In this modification, the method of local tomography could be used tostudy both cells and cellular structures, because it is not necessary to probe a full field of view. Local probingof the region of interest during the functioning of the nerve cell will, first, reduce the time of data recordingfor obtaining local tomograms and second, provide the opportunity to explore the dynamics of several regionsinside the cell at the same time.
