With 1,024 flexible nerve probe channels, the device named Neuroscroll can simultaneously identify the individual activities of nerve fibers.
Chinese researchers have developed a nerve probe device with up to 1,024 channels, a powerful tool for monitoring neural activities across multiple regions while exploring the relationship between neural activity and behavioral research.
Nervous System.
This work was recently published in the journal Nature Neuroscience.
The device, named Neuroscroll, has an adjustable length ranging from 1 to 10 cm, allowing it to conduct nerve probing for various brain sizes, from rodents to primates.
With its 1,024 flexible nerve probe channels, this device can simultaneously identify the individual activities of nerve fibers.
According to scientist Duan Xiaojie from Peking University and the research team leader, the device has been tested to fully record the activity of over 700 neurons in the brains of long-tailed macaques. This is the world’s first experimental model using this method.
Additionally, the team also tested this device on mouse brains over a period of two years, demonstrating the tool’s stable and long-lasting performance, as well as high biocompatibility.
Mr. Cheng Huabing, Director of the National Biomedical Imaging Center at Peking University, stated that this research represents a breakthrough, providing an effective tool to simultaneously monitor neural activities across multiple brain regions and explore the relationship between neural activity and behavioral research.
According to this researcher, using multiple devices of this type simultaneously could increase the number of nerve probe channels to tens of thousands, thereby obtaining larger datasets. This serves as a foundation for advancing neuroscience research, such as understanding the interactions between the brain and machines, opening up new research potentials in this field.
