  • Patent number: 10520493
    Abstract: A method for assessment of neural function by establishing an analysis module is revealed. The first step of the method is to capture images of the cultured cells with a plurality of fluorescence labeling by a fluorescence microscopy system for image analysis. The cultured cells include neurons and non-neuronal cells. Then select neurons with neurites having fluorescence labeling and exclude non-neuronal cells according to an area and a fluorescence intensity of nucleus. Also calculate an area of the neuronal cell body, a length of the neurites and a number of processes and branches to verify outgrowth of the neurites of the neurons. Next calculate a number of synaptic puncta having fluorescence labeling on the area of the neurites having fluorescence labeling defined in Step 2 to verify formation of the synaptic puncta of the neurons for assessment of neural function.
