Australian scientists cultivate brain cells on the chip: the future can treat neurological diseases

In the field of artificial intelligence, an algorithmic model that mimics the structure and function of biological neural networks (especially the brain) is called an artificial neural network. The use of these algorithms also requires a chip with powerful data processing capabilities as a carrier.

But now, it seems that scientists can have new ways to play, neither need to imitate nor need carriers, because recently there are reports that Australian researchers have directly developed brain cells on the chip.

The report is based on a paper published by relevant researchers in the well-known academic journal Nano Letters, introducing the new devices they developed.

This material is generally used in the fabrication of LEDs and solar cell devices by building nanotube holders of indium phosphide materials on semiconductor chips, and is said to be used for the first time in the field of connection with brain cells. These nanotubes were arranged in a square grid, and about 50 rodent brain cells were placed on each scaffold, followed by culture observation.

And just as the meaning of a single computational component is limited, on this device, Australian scientists not only cultivated brain cells, but also reconstructed the circuits of these nerve cells. It is said that this is the problem that has been faced in the laboratory exploration.

The author of the innovative study, Vini Gautam, a biomaterials engineer at the Australian National University, said they hope to explore the brain signal processing process through the device. More basic, even the growth and connection of neurons. Because of the laboratory conditions, the connections of the cranial nerves tend to have a relatively large randomness. However, in a real brain environment, the connections of neurons often have a certain degree of orientation. And to sum up this guiding law has become a fundamental problem in neuroscience.

Automatic Massage Foot Bath Machine

The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.
