Neuro Localizer

A Tool for Finding the Lesion

Neuro Localizer Logo

Designed by a team of neurologists at the University of Michigan, Neuro Localizer is a free application for medical professionals interested in exploring the basics of neurologic localization – or for anyone who wants to know more about how the nervous system works.

The human nervous system is made up of a number of overlapping and crossing pathways.  We have determined that the same pathways are found in the nervous system of the gingerbread man.

When a person – or a gingerbread man – has neurologic deficits, you need to know where the problem is in order to figure out what it is. This exercise is called “localizing the lesion,” and Neuro Localizer will help you do it.

Neuro Localizer

Here is how it works: Enter symptoms or abnormal exam and the neuroanatomic pathways are drawn out for you. Which muscles are weak? Where is the patient numb? Are the eye movements abnormal? Are the reflexes brisk or hypoactive? As you add more signs, Neuro Localizer will show you where your pathways overlap in the central or peripheral nervous system.

Still stumped? Ask for a suggestion, and Neuro Localizer will list other signs that could help refine your localization further.

Once you’ve found the lesion, you don’t need to ask for any more help localizing, but that doesn’t mean you know everything. Ask for another suggestion, and Neuro Localizer will give you some candid life advice or tell you a really great joke about neurologists and/or gingerbread cookies.

Neuro Localizer, because this lesion isn’t going to localize itself.

This application was funded through the generosity of the Jerry Isler Neuromuscular Fund.

Neuro Localizer is an educational tool only. The pathways represented are simplifications of those seen in real patients. Anatomic variations exist, and Neuro Localizer cannot identify multifocal or diffuse processes. For those reasons, it should not be used to make clinical decisions, unless the patient is made of gingerbread.
