We have developed multi-thousand channel µECoG technology, which offer high spatial and temporal resolution for mapping brain activity. The grids were tested in rats and humans, providing submillimeter functional organization resolution and fine temporal dynamics resolution. µECoG grids also identified epileptic discharges in a patient undergoing epilepsy surgery. The technology has the potential to revolutionize clinical mapping and research in brain-machine interfaces.

Brain-Gut Axis

The µECoG technology, which provides high spatial and temporal resolution for mapping brain activity, has potential applications in understanding the electrophysiological interaction between the gut-brain axis. Specifically, it can be used for gut-neural interfaces, allowing for a better understanding of how the gut and brain communicate with each other.

Nanoscale Neuron Interface Devices

To better understand the microscopic, individual cell level intracellular activities of the nervous system in an intact brain, we have developed nanoscale probes for intact brain tissue.

 Semiconductor Optoelectronics for Brain and Neuron Interfaces

A new neurotechnology has been developed that integrates flexible micro light-emitting diode (μLED) arrays with micro-electrocorticography (μECoG) cortical grids. This LED+ECoG technology provides real-time visual feedback directly from the brain surface, allowing for precise identification of cortical landmarks and lesions. The integration of electrophysiological devices and display technologies has the potential to improve patient outcomes by increasing accuracy, reducing procedure time, and avoiding harm to neurological function. This technology is a significant advancement in neurosurgery and may have broad applications in neuro-oncology.
