In this new format, Veterinary Neurology and Neurosurgery Journal (VNNJ) has entered a new stage. A dedicated team of volunteers has joined together to perform the necessary work. With several persons working in its production, plus the important alliance with Veterinary Information Network, VNNJ will be able to have all qualities of the best and most highly respected veterinary journals.
Readers and authors should note that the VNNJ electronic format minimizes the time the author must work to reach the readers. Papers are submitted electronically. Peer review correspondence entirely by e-mail helps, and hard-nosed editors (who prod reviewers to complete their jobs quickly) reduces the time often wasted during this traditionally slow part of publication. When a paper is ready, the time necessary for the information to reach its worldwide audience is reduced to seconds through the Internet. Print journals have attempted to duplicate this ability by duplicating their print formats in parallel electronic formats. But they still seem to lose months, or sometimes even years; it seems the two formats are, of necessity, in lock step, the one holding back the other.
Another distinct advantage of electronic publication is the ease of publishing illustrations. Authors can publish their very best color illustrations and all forms of diagnostic imaging. Editors need not feel they must restrict the use of color or the use of additional space for multiple illustrations. Importantly, video and sound are possible, for the benefit of both authors and readers, an especially valuable feature for neurological subjects (for these are, in essence, disorders of movement, sometimes too little, sometimes too much).
Finally, VNNJ will receive contributions not only from North America but also from the entire globe. Thus those creating the important developments now underway in Veterinary Neurology in South America, Central America, Asia and Europe will be encouraged by the use of the electronic format and the opportunity to see their work published promptly in a peer-reviewed journal.
Personally, I am looking forward to the future of VNNJ, under the guidance and inspiration of this new team of workers who undoubtedly will propel it into an outstanding future.

Scalp and Thoracolumbar Recorded Somatosensory Potentials Evoked by Tibial Nerve Stimulation in Cats
The purpose of this study was to define tibial somatosensory-evoked potentials (SEPs) in 56 clinically normal adult cats. The potentials recorded from the gastrocnemius muscle, sciatic nerve, L3-L4 and T12-T13 interarcuate ligament and scalp were evaluated. Central conduction time was determined by the difference between first scalp negative peak and first lumbar negative peak latencies. The initial small triphasic waves which represent the sensory nerve action potentials from sensory or mixed nerves into the spinal cord were observed in the lumbar area of 24 cats and in the thoracic area of 15 cats. The end point of the last positive potential was unclear. Amplitudes acquired from the muscle, sciatic nerve and scalp were conventional while the ascending evoked potential (AEP) was similar to that of the cord dorsum potential. According to the latency values, all the recorded potentials showed homogeneous dispersion except for the lumbar P1 and thoracic P2 latency values. The latencies of the lumbar and thoracic potentials' peaks were significantly different except for the lumbar and thoracic inter-peak and P2 and P4 latencies (P<0.05). This study concluded that the somatosensory-evoked and spinal cord-evoked potentials may be used to assess the functional integrity of the ascending tracts of the spinal cord, as well as sensory nerves, dorsal nerve roots and spinal cord dorsal horns in cats
