Neuronal Signal Activity Image Classification, Ardavan Vakil, Miad Faezipour

Purdue Polytechnic Graduate Student Poster Symposium

Neurodegenerative disorders can cause signal disturbances on the neuronal spiking patterns within the brain. Parkinson’s disease, as an example, produces burst firings and synchronized oscillatory signal patterns. Accurately distinguishing between different brain spiking pattern activities is essential in finding effective neuromodulation or neurostimulation treatments for neurodegenerative disorders like Parkinson disease. Due to the lack of publicly available neuronal spiking pattern datasets containing different neuronal signal patterns and classes, we propose the generation of a novel three-class dataset. We then convert the generated signals into 2D images and separate the generated signal images into test and train datasets. We aim to …
