Project Description<br />
Neurobiologists are interested in understanding how neurons form complex synaptic circuits during<br />
development and how these processes are perturbed in diseases. Neuronal migration and maturation<br />
during development play a critical role in how neurons ultimately function. Development of<br />
computational methods to extract pertinent information from the large three- and four-dimensional image<br />
data sets has not kept pace with available imaging technologies. This project will develop a set of analysis<br />
methods that allows researchers to discover relationships between the anatomical and migratory<br />
characteristics of neurons and their ability to function in a network of cells. These methods will provide a<br />
foundation upon which a comprehensive suite of tools can be developed. The biological questions that<br />
these tools will address strike at the foundation of many neurological disorders including Alzheimer’s,<br />
Parkinson’s, and schizophrenia.<br />
Mission Relevance<br />
Although the initial application of this research is for analysis of cellular morphology and migration<br />
within animal models, the results may be applicable to cellular analysis of morphology and migration for<br />
plant materials targeted for bioenergy. In addition, the techniques learned during development of motion<br />
tracking methods for neuron cells may be useful for motion detection in security applications where<br />
people must be monitored in a facility. The same concept may be applied to intelligent energy delivery<br />
(e.g., of light, and heating, ventilating, and air conditioning) by monitoring and tracking the location of<br />
people within a facility and delivering energy based on location and activity, or task. This work will<br />
benefit the <strong>National</strong> Institutes of Health (NIH). The project addresses the needs of a program entitled<br />
“NIH Blueprint for Neuroscience Research,” which looks for new methods, tools, instrumentation, etc.,<br />
that will have benefit to multiple <strong>National</strong> Institutes, such as Neurological Disorders and Stroke, and<br />
Biomedical Imaging and Bioengineering. Also, the project can benefit the Department of Defense,<br />
particularly in the areas of neuronal interfacing for prosthetics and traumatic brain injury.<br />
Results and Accomplishments<br />
Our collaborators at St. Jude Children’s Research Hospital provided us with a large data set of retinal<br />
horizontal neuron imagery. The dataset consists of 95 confocal image stacks of developing mouse retinas,<br />
each covering an area of 200 200 μm and a depth of roughly 150 μm and containing on the order of<br />
10-20 neurons. The images were acquired from both wild-type and knockout genotypes at various stages<br />
