Spatiotemporal Dynamics of Visual Neurons
This summer, I will be using MATLAB to investigate the development of spatiotemporal dynamics in 8-week kittens and adult cats. Previously, the cats were presented with a series of visual stimuli, and electrode measurements were taken to identify the neurons receptive fields, which characterize the response of each neuron to each point in space and time. I will be applying various computational techniques to determine how these receptive fields change over short time intervals, providing insight into how course-fine tuning and binocular vision is achieved. By comparing these spatiotemporal dynamics in different brain regions for kitten and adult cells, I hope to learn more about the development of early visual pathways and neural plasticity. Because the feline visual system is very similar to that of humans, these results may have numerous applications in identifying and correcting visual disorders that are manifested during human development.
