A method for 2D reconstruction of intracellularly labeled neurons from sequential sections.

• A technique for 2D reconstruction of intracellularly labeled neurons from sequential sections is described. The system consists of a Charged Coupled Device-camera mounted on a microscope, a videomixer and a IBM-compatible PC with a framegrabber. The neurons (interneurons from the spinal cord of the cat) were labeled iontophoretically by horshradish peroxidase and subsequently cut in 60 microns sections. The sections were aligned using the video mixer by fitting the cut dendrites and axon from one section with their counterparts in the following section. The images were then digitized in the PC where they were fused to create a superimposed picture of the aligned parts of the neuron; a 2D reconstruction was created.
