Neuroprobe with more than 1,000 channels

Chinese researchers have developed a neural detector with up to 1,024 channels, a powerful tool for both monitoring neural activity across multiple regions and exploring the relationship between neural activity and behavioral research.

The device, called Neuroscroll, has an adjustable length from 1-10cm, allowing it to perform neural probing on brains of various sizes, from rodents to primates. With 1,024 flexibly arranged neural channels, the device can simultaneously identify the activity of individual nerve cells. The device has been tested to fully record the activity of over 700 neurons in the brain of a long-tailed macaque.

According to Cheng Heping, Director of the National Center for Biomedical Imaging at Peking University, the research is a breakthrough, providing an effective tool to simultaneously monitor neural activity across multiple brain regions and explore the relationship between neural activity and behavioral research. This lays the groundwork for advancing neuroscience research, such as how the brain interacts with machines, opening up new research potentials for this field.
