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 work was recently published in the journal Nature Neuroscience .

The device, called Neuroscroll, is adjustable in length from 1cm to 10cm, allowing it to perform neuroprobes on a wide range of brain sizes, from rodents to primates.

With 1,024 flexibly arranged nerve probe channels, this device can simultaneously determine the individual activity of nerves.

According to scientist Duan Xiaojie from Peking University and the leader of the research team, the device was tested to fully record the activity of more than 700 neurons in the brain of a long-tailed macaque monkey. This is the world's first experimental model using this method.

In addition, the team also tested the device on mouse brains for 2 years, showing the tool's stable and long-lasting performance, as well as its high level of biocompatibility.

Cheng Heping, director of the National Center for Biomedical Imaging at Peking University, said the research was a breakthrough, providing an effective tool to simultaneously monitor neural activity in multiple brain regions and explore the relationship between neural activity and behavioral research.

According to the researcher, using multiple devices of this type at the same time can increase the number of neural probe channels to tens of thousands, thereby collecting larger data. This is the basis for promoting neuroscience research, such as how the brain and machines interact, opening up new research potential for this field of science.
