Neuralink is on a mission to develop high-bandwidth, implantable brain-machine interfaces (BMIs) or BCIs. These devices allow people to communicate with computers and other devices directly through their brains, potentially improving memory, controlling prosthetics, or even merging with artificial intelligence.
In this blog post, we will take a closer look at the progress Neuralink has made and discuss the potential future implications of these technologies.

What is Neuralink?
It is a neurotechnology company founded in 2016 to develop implantable BMIs that allow for high-bandwidth communication between the human brain and external devices. To achieve this goal, the company is developing a range of technologies, including ultra-low power integrated circuits, flexible threads for brain implants, and advanced machine learning algorithms for decoding brain signals. These technologies are intended to be used in combination to create a seamless interface between the brain and external devices.
Progress to Date
Since its founding, Neuralink has made significant progress in the development of its technologies. In August 2020, the company demonstrated a working prototype of its BMI system in a live surgery, which was broadcast on YouTube. The demonstration showed a macaque monkey controlling a computer cursor and a robotic arm using only its brain activity, as recorded by electrodes implanted in its motor cortex.
This demonstration was followed by several other events in which BMI company publicly demonstrated its technology. In November 2020, the company presented a further update on its progress, including a demonstration of a BMI system implanted in a pig. In this demonstration, the pig’s brain activity was recorded and used to control a video game. In April 2021, Neuralink held a presentation demonstrating a BMI system implanted in a human subject for the first time. In this demonstration, an employee was able to control a cursor on a computer screen using only his brain activity.
In addition to these demonstrations, Elon musk’s company has also made progress in developing its BMI system’s hardware and software components. The company has developed a flexible thread with a diameter of just 20 microns, capable of carrying thousands of electrodes, and can be implanted in the brain with minimal trauma. These threads are intended to be used in combination with Neuralink’s ultra-low power integrated circuits, which are designed to transmit and receive signals from the brain over long periods of time. The company also revealed a smartphone app that is in development.
Future Implications
The potential implications of this technology are vast and varied. In the short term, the company is focusing on developing treatments for neurological conditions such as paralysis and memory loss. In the longer term, however, the possibilities are much broader.
One of the most exciting potential applications of BMIs is the possibility of merging with artificial intelligence. This could allow humans to enhance their cognitive abilities beyond their natural limits, potentially enabling us to solve problems and make decisions exponentially faster.
However, the development of BMIs also raises ethical concerns. There are questions about the potential risks associated with brain implants and the potential for these technologies to be used in ways that are harmful to individuals or society as a whole. It will be necessary for researchers and policymakers to consider these issues as the technology continues to develop.
Challenges
One of the main challenges the company faces in developing its BMIs is the need to transmit and receive large amounts of data from the brain. Current systems are limited in the amount of data they can transmit and receive, limiting their potential applications. However, the company is working on ways to increase the bandwidth of its BMIs, including developing new hardware and algorithms capable of handling larger amounts of data.
Another challenge the company faces is the need to make its BMI systems practical and safe for humans. This includes developing hardware that is durable and biocompatible, as well as software that is reliable and easy to use. It will also be essential to address any potential ethical concerns that may arise as these technologies are developed and deployed. The challenges in this field are numerous. All the challenges listed could be a separate post on their own.
