Measuring and manipulating neuronal signals using implantable electronic microsensor arrays
Problem: Most current implantable brain devices stimulate large regions of the brain without sensing. These devices are not able to access the fine multi-scale architecture comprising brain function and do not interact with the brain’s capacity for self-reorganization and repair. Solution: An implantable electronic micro-sensor array on...
