The goal of the NeuroEngineering Group at Usach is to contribute to the understanding and improvement of electrical neuromodulation therapies by means of computational modeling and engineering techniques. As well, we aim to provide engineering tools and analyses to understand neural system function.


Complexity analysis in electrophysiological signals

Healthy states appear to be more complex than those observed in disease. We perform complexity and entropy analyses of physiological signals to provide tools for diagnosis.

Nerve fiber modeling

We are analyzing computational models of nerve fibers to understand how they respond to high-frequency stimulation waveforms. Our goal is to use mathematical modeling and engineering techniques to improve existing models and contribute to the improvement of electrical neuromodulation therapies.

Noninvasive Electrical Stimulation of the Spinal Cord for Pain Management

We are developing computational models of noninvasive electrical stimulation to design strategies that are able to reach spinal cord structures using surface electrodes. Modulating the activity of nerve fibers or neurons in the spine is being used for pain relief in people with chronic pain.

Quantification of direction selectivity in a network model of the retina

We are studying the phenomenon of direction selectivity to light stimuli in the retina by means of computational models of retinal cell networks.
