PROJECT NARRATIVE Given that decoding ability from neural recordings increases with the number of recording electrodes, new innovations are being developed with high-channel neural recordings in animal models, though translation to humans is currently limited to only 100 channels. Here we propose preclinical and clinical studies to optimize our high-channel count, microwire arrays for safe and reliable insertions and determine chronic viability of the arrays, focusing on translation towards a medical device. This could revolutionize brain-computer interfaces by increasing the degrees of freedom to decode neural activity, potentially enabling people with locked-in-syndrome new tools to interact with the world.
