Neuralink: A Brain Inside the Brain!

“Machine intelligence is the last invention humanity will ever need to make.” - Nick Bostrom

We always wonder what the future holds for us, especially in terms of technology. Looks like Neuralink can give us a sneak peek of it. Neuralink is a device created by the Neuralink Corporation, founded by Elon Musk and Max Hodak. It is surgically implanted into one’s brain which allows one to communicate with machines and even control them with wire or wirelessly.

It is a device 8mm in diameter which is implanted in your skull and has multiple wires containing electrodes that receive signals from the neurons. However, the implantation of such a device is intricate. Therefore, robots have been specifically designed to carry out deft and precise insertion of the device into the cortex. The robot will insert the device into one’s brain using a microscope and minuscule needles.

How does it work?

I shall begin with explaining that by telling you about the basic component of the brain, the Neuron. The neuron consists of dendrites, the soma, and the axon. Each of these parts has its function. The signal is received by the dendrites, then processed by the soma, and then transmitted to other cells by the axon. The neurons are connected to each other by the synapses which release neurotransmitters. These neurotransmitters are then sent to another neuron’s dendrite causing the flow of current across the neurons. The electrodes present in the wires of the Neuralink will read the electrical signals and then output them in the form of action.

What is the purpose of Neuralink?

Neuralink aims to start by focusing on helping people deal with their brain injuries, spinal cord injuries, or inborn defects. It can also be used to draw pictures, take photographs, listen to music, etc. but the company discourages introducing such features in its initial stages.

Nonetheless, there are still some concerns that surround this invention. One of them is that Neuralink is vulnerable to malicious attacks, which makes its safety questionable. In conclusion, the time has come when we can start expecting and accepting the revolutionary changes Artificial Intelligence is bringing while being aware of its advantages and disadvantages.
