Neuroprobe with more than 1,000 channels

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

The device, called Neuroscroll, is adjustable in length from 1 to 10 cm, allowing it to operate on a wide range of brain sizes, from rodents to primates. With 1,024 flexible neural probe channels, the device can simultaneously detect the activity of individual neurons. The device has been tested to fully record the activity of more than 700 neurons in the brain of a long-tailed macaque monkey.

According to Mr. Cheng Heping, Director of the National Center for Biomedical Imaging at Peking University, the above research is a breakthrough, providing an effective tool to simultaneously monitor neural activities in multiple brain regions and explore the relationship between neural activities and behavioral research. This is the basis for promoting neuroscience research, such as how the brain and machines interact, opening up new research potential for this science.
