Image datasets are acquired by fluorescence microscopy and depict neuronal networks of hippocampal in-vitro cultures.

NOTE: Due to the high image resolution, full size datasets are downloadable in .rar format. A low resolution preview is also available, when needed. For some datasets, due to publishing constraints, only small crops of the original image are available. Original datasets are in .tif format, but have been converted in compressed .jpeg format for an easier visualization.
