Exploring Cortical Connectivity of Visual Prosthesis Users: Resting-State Study

Electrophysiological studies reveal significant organizational and functional differences in the cortex of blind individuals compared to sighted individuals. These differences result from the nervous system’s reorganization to adapt to new sensory modalities used in daily life. Cortical visual prostheses offer a means to restore visual sensations in blind individuals by generating phosphenes, luminous perceptions that provide information about their surroundings. This study investigates the cortical changes associated with the use of a visual neuroprosthesis, focusing on how the brain adapts to the restored visual input. Our findings aim to contribute to understanding neuroplasticity in sensory restoration processes.
