If you are wondering, ‘Neuralink how many Electrodes?’ You are not alone. A Neuralink implant can record from 1,000 neurons in a rat’s brain. But even if you can implant the device in 1,000 neurons, the electrodes are not enough to stimulate the entire brain. The company is currently looking for people to work on their brain-machine interface system. However, they say that they have a plan to expand the number of electrodes they have in the future.
A big concern about the technology is safety. The company is closely working with the FDA to ensure safety and is aiming to begin human trials later this year. The Neuralink is surgically implanted into the brain by a neurosurgeon and contains a chipet called the link. The electrodes have insulated wires connected to it. This chipet can then operate a computer or smartphone.
Although a commercial system might contain as many as 3,000 electrodes, the company is not yet ready to release its plans for a full-scale production of the system. However, the Neuralink is expected to provide data for 15 times more neurons than current systems embedded in human brains. It could also surpass Imec Neuropixels technology. For now, a commercial system may consist of up to 3,072 electrodes and 96 threads.
The next step in the development of a Neuralink implant is to develop its robotic technology. The robotics that place electrodes in the brain can insert them at a rate of 30 to 200 per minute. With this new technology, the Neuralink will need to increase data bandwidth since recording from 1,000 electrodes would require a lot of information. Ultimately, it will have to compress the data and relay it via Bluetooth.
The company claims that their technology is capable of implanting 192 electrodes inside a human brain. Neuralink is the company that provides everything needed for the process. They provide the electrodes, the software, and the machine that sews human brains together. Using five-micron electrodes, Neuralink is aiming to be at the forefront of neurosurgery and will install updates on human brains.
The Neuralink ASIC is at the core of its modular recording platform, which enables easy replacement of constituent parts. The Neuralink ASIC also has on-chip ADCs that sample at 19.3 kHz with a 10-bit resolution. The entire system uses only six milliwatts, including the clock drivers. It is packaged in a titanium case with parylene-c coating. This is intended to keep it sterile and protected from moisture.
Neuralink systems A and B were implanted into male Long-Evans rats. Neuralink’s procedures were approved by the Institutional Animal Care and Use Committee (IACUC). Each of the two systems can record 1344 of 1536 channels simultaneously, while System B can record all 3072. Then, the digitized broadband signals are processed in real time using an online detection algorithm. The Neuralink technology enables scientists to monitor a patient’s brain activity in real time.
While Neuralink has yet to show the completed device, it has already made progress. The company’s prototypes are smaller than a silver dollar and a few centimeters thick. The technology is a breakthrough in medical research, and the company hopes to use it to create more useful products. And this is only the beginning. Its future is in our hands, so we’ll have to wait and see.
In the meantime, the company has shared a video of a monkey playing ping pong with a Neuralink device. If this technology works, human tests may begin within a year. By 2020, the team hopes to begin human trials with their device. However, the device needs to advance a lot before it can be put to the test. It isn’t yet available to the public, but it could help people with disabilities.
Another pig, named Gertrude, underwent a Neuralink implant to improve her behavior. The implanted pig was able to nuzzle her handlers and was indistinguishable from a normal pig. The results of the Dorothy pig’s experiment will help humans who wish to upgrade their implants. Neuralink says that they are a good choice for testing since pigs’ skull and dura membrane are so similar to humans’. And as a result, they can perform useful experiments, such as walking on treadmills.
