The actual image is great, and I love both public domain and SVG. Zakolantern 22:51, 13 July 2007 (UTC) Can someone please teach me (my talk page or here) how to link to an image page without the image appearing? (I want the link I used to go to Image:Eye-diagram_no_circles_border.svg, without the image appearing. I failed. Thank you.

The two main neuronal classes in the cerebral cortex are excitatory projection neurons (around 70-80%) and inhibitory interneurons (around 20–30%). [2] Neurons are often grouped into a cluster known as a nucleus where they usually have roughly similar connections and functions. [3] Nuclei are connected to other nuclei by tracts of white matter.
Neurons are highly specialized for the processing and transmission of cellular signals. Given the diversity of functions performed in different parts of the nervous system, there is a wide variety in their shape, size, and electrochemical properties. For instance, the soma of a neuron can vary from 4 to 100 micrometers in diameter. [7]

Digital reconstruction or tracing of neuron morphology is a fundamental task in computational neuroscience. [1] [2] [3] It is also critical for mapping neuronal circuits based on advanced microscope images, usually based on light microscopy (e.g. laser scanning microscopy, bright field imaging) or electron microscopy or other methods.
