Neuralink is recruiting for great engineers to make brain repair affordable and reliable. They implanted brain read-write devices into brains in pigs. They have received emergency FDA approval in July and will soon implant into humans in clinical trials.

They need chip designers, software people, product designers and robotics people. The team has 100 people now and eventually, they will have 10,000 people.

The sensors are like little microphones that “listen” for brain spikes. Brain spikes are action potentials in neurons that are the main means of communication in neurons.

The goal is to make it faster, safer, smaller with millions of brain sensors and provide to millions of patients with fully automated implantation.

The first clinical trials will be in people with severe paralysis.

Pigs are great models for research and can prove the robustness of the devices.
The neuralink devices will approach the cost of smartwatches.

They have a full custom ASIC with an analog front end to amplify and sense the microvolt signals. They need to be very energy efficient.

An affordable, reliable and brain interface with thousands to millions of two-way probes will be able to fix

* memory loss
* hearing loss
* blindness
* paralysis
* depression
* insomnia
* extreme pain
* seizures
* anxiety
* addiction
* strokes
* brain damage

All of your senses could be improved or restored.

It is less than the thickness of your skull. It is inductively charged so it charges like your smartphone.

They are making a really good surgical robot.

A coin-sized piece of skull if removed and the robot inserts the coin-sized device and all of the electrodes.

They have installed the 1024 brain electrode implant into a pig for two months and they used dual brain electrode implants into three pigs.

They have implanted the link into and out of pigs.

Right now they are limiting implantation depth to the first 3-4 millimeters of the cortex. Hearing, sight, and paralysis are solvable at this depth. They plan to go deeper. They will need longer wires and adjust the robot to go deeper. The wires are 7 mm long. They will need to solve sensing problems to avoid veins.

They think they can go sub-micron threads from 5-micron threads.

They will enable people to get upgrades of the devices.

They will be able to enhance senses. Sight and hearing could go beyond human ranges. We have those kinds of sensors now in planes and cars and the feeds could be converted and fed to the visual or hearing areas of the brain.
