"Revolutionary Neural Implant Reads Deep Brain Activity from Surface"

Researchers at UC San Diego have developed a transparent graphene-based neural implant that can record electrical and calcium activity in deep brain layers, overcoming previous implant limitations. The implant's high-density array of tiny graphene electrodes allows for simultaneous recording of neural activity and optical imaging, revolutionizing neuroscience research. The technology, tested in transgenic mice, aims to provide high-resolution data about deep neural activity and could lead to the development of minimally invasive brain-computer interfaces for studying brain function.

"Revolutionary Brain Implant Reads Deep Neural Activity"

Researchers at UC San Diego have developed a transparent, flexible neural implant with a dense array of graphene electrodes that can capture high-resolution information about deep neural activity while sitting on the brain's surface. The implant overcomes the limitations of current technologies by enabling the prediction of deep neural activity from surface signals, allowing for longer duration experiments and a more comprehensive understanding of neural activity in real-world scenarios. The technology's transparency and high electrode density, combined with machine learning methods, make it possible to simultaneously record electrical signals and optically image neural activity, providing a clear field of view for imaging experiments. The team aims to test the technology in different animal models with the goal of human translation in the future.
