Scientists from China have used astronomical observation techniques to study the neural pathways of zebrafish brains. 

This pioneering research has produced real-time imaging analysis of up to a hundred thousand neurons in zebrafish for the first time.

This has helped in understanding the intricate workings of fish brains and advancements in brain-computer interface (BCI) technology.

The researchers at the Centre for Excellence in Brain Science and Intelligence Technology at the Chinese Academy of Sciences (CAS) have developed a system capable of continuously monitoring the activities of zebrafish brains with unprecedented precision. 

With a feedback delay of less than 70.5 milliseconds and the ability to handle data streams of up to 500 megabytes per second, this innovative system represents a significant leap forward in optical BCI technology.

The study, led by brain scientists Mu Yu and Du Jiulin and algorithm specialist Hao Jie, holds promising implications for the future of brain-computer interfaces.

By decoding neural signals in real-time, the system enables the zebrafish brain to act as a light-controlled switch, potentially facilitating control over external devices with thoughts.

Drawing inspiration from astronomers’ techniques for processing vast amounts of astronomical data, Chinese researchers have devised a method for efficiently processing neural signals in zebrafish brains. 

Like the technology used to study fast radio bursts (FRBs) in deep space, this system leverages computer learning powered by graphics processing units to analyze complex neural signals and decode them instantaneously.

The system’s versatility is demonstrated through its application in various neuroscience research scenarios, including real-time optogenetic stimulation, visual stimulation, and virtual reality control. 

By identifying characteristics of neural activity suitable for optical BCI, the researchers aim to unlock the mechanisms underlying brain-computer interfaces and pave the way for future more efficient and advanced BCI technologies.

The implications of this research extend beyond the realm of neuroscience, offering insights into the fundamental nature of the brain and its parallels with the universe.

With nearly 100 billion neurons in the human brain and an interconnected network resembling the universe’s structure, the study highlights the profound interconnectedness of the microcosm and macrocosm.

China’s pioneering work in fish brain imaging represents a remarkable convergence of neuroscience and astronomy. It offers unprecedented insights into the complexities of neural networks and opens new frontiers in brain-computer interface technology.
