Our human brain consists of more than a
billion neural cells that process information, including sensation and
cognition. Each neuron works like a simple processor and only their massive
interaction and parallel processing make the brain's abilities possible.
Understanding how neural networks work and thus employing the methodology to
inspire artificial intelligence, is one of the significant subjects in modern-day
science. Lingjie Kong, an associate professor at the Department of Precision
Instrument at Tsinghua University, is keen on inventing new techniques and
instruments to overcome this challenge.
Patch-clamp recording is a traditional way
to observe brain activity, but it is invasive and of low spatial
resolution. Kong has developed several novel neuroimaging tools for recording
neuronal network activity in conscious animals. For example, he and his
collaborators have invented a macroscope of sub-micron-resolution with the
largest field-of-view (centimeter scale) and the highest throughput (GB/s)
worldwide, which enables real-time imaging of whole-brain activity in vivo.
Analyzing the statistical data obtained through these methods can help reveal the mechanisms of the brain and inspire the development of artificial
intelligence. So far, Kong and his team have helped several leading labs around
the world in duplicating the systems for their brain research.
