Metta and I are still in the process of collecting images of a serial section dataset through the front end of our nematode. I am hoping it will eventually become the second species for which we have a complete connectome, or “wiring” diagram of all the synaptic connections in the nervous system. We have now imaged everything from the tip of the nose to the brain of the animal, which is called the nerve ring as it wraps around the pharynx making a ring shape. Everything is going exceptionally well, and we only need a few hundred more images to have a very complete and useful dataset showing all of the connections. The above image is a cross section of the nematode. The pharynx is in the middle, and you can see the neuropil wrapping around in a circle, forming synapses as they pass each other. All of these images are taken at much higher resolution than is shown here. Click HERE for a Flickr gallery showing the same image at different magnifications.
