Neuralink is developing a brain-machine interface called "The Link" that will be surgically implanted in the brain. The Link processes and transmits neural signals to help treat neurological disorders and potentially enhance normal brain function. It consists of flexible threads that are implanted using a robotic system, with each thread containing many electrodes to detect neural activity. The goal is to help paralyzed people control devices and eventually provide a direct communication interface between the human brain and machines.

2. INTRODUCTION
● As the days are passing by, we come across new and latest
inventions which use Artificial Intelligence to ease our usage of the
devices
● And out came the solution, mix both the intelligences and achieve a
symbiosis between human and Al. To achieve this
● we can use the "Neural Lace" technology as well as BrainMachine
Interface (BMI

3. A Direct Link Between the Brain &
Everyday Technology
The initial goal of our technology is to help people with paralysis
regain independence through the control of computers and mobile
devices. Our devices are therefore currently being designed to one
day give people the ability to communicate more easily via text or
speech synthesis

4. WHAT IS NEURALINK ?
● Neuralink is a device, specifically, a Brain-Machine Interface
● That will be surgically implanted into your brain and with it
● You'll be able to communicate with machines and even control
them

5. WHY NEURALINK ?
● Helps people with severe spinal cord injury by giving them the
ability to control computers and mobile
● Preserve and enhance your own brain
● You'll be able to communicate with machines and even control
them
● Restoring motor and sensory function and the treatment of
neurological disorder

6. OVERVIEW
● The Link processes, stimulates, and transmits neural signals
● Surgically transplanted inside head
● t has potential to treat brain disorders and other medical
problems

7. ELECTRONICS
● Application specific integrated circuit (ASIC) is used
● PCB-printed circuit board
● Each system consists of a field-programmable gate array (FPGA)
○ Accelerometer
○ A single USB- C connector
○ Real time temperature

8. NEURAL THREAD
● Each small and flexible thread contains many electrodes for
● detecting neural signals.
● Thread thickness is nominally 4 to 6 pm.
● Typical thread length is approximately 20 mm.
● The main substrate and dielectric used in these probes is polyimide.
● Each array has 48 or 96 threads, each of those containing 32
independent electrodes
● Metal film are sub-micron resolution

9. WORKING
● Principle of Brain Machine Interface. •
● Neurons communicate with each other by sending and receiving
very small electrical signals, these signals can be heard with
advanced electrical sensors.
● Signal processing has
○ Preprocessing
○ feature extraction and
○ feature translation.

10. HOW NEURALINK IS DIFFERENT FROM OTHER
BMI DEVICES ?
● There are currently only a few approved devices for recording or
stimulating from the human brain
● These are designed to modulate the activity of whole brain
areas, not to transfer information to and from the brain
● The Link has more electrodes and with flexible threads

11. HOW IS IT PLACED IN THE BOD
● A robotic system will be used.
● The neurosurgical robot capable of inserting six threads per minute.
● Have an auto-insertion mode feature
● Each thread can be individually inserted into the brain with micron
precision.
● The needle is driven by a linear motor allowing variable insertion speeds
and rapid retraction acceleration

12. Look like

14. CHALLENGES IN MAKING SCALABLE BM
● The threads have to resist corrosion from fluid in the tissue, and
the electrodes must
● Scaling these devices requires on-chip, real-time identification
and characterization of neural spikes
● Design adaptive algorithms that maintain reliable and robust
performance

15. CONCLUSION
● Neuralink has developed advanced solution to existing medical
problems.
● It will surely create a well aligned future.
● Implantation will be done in less than a hour and leave hospital
the same day.
● Neuralink is still at an early stage (it's at version 0,9).
● We have no current idea of how much the brain chips will cost
