Neuralink -Opening solution for Neurological diseases 

Neuralink, a brain-machine interface, aims to help individuals with neural disorders by recording and decoding neural signals from the brain, then transmitting them back to the brain using electrical stimulation, for  individuals to regain control over limbs, prosthetics, or even communication devices.

For example, someone with paralysis could use their thoughts to move a cursor, type on a keyboard, or control a robotic limb.

Neurological diseases Neuralink helps?

Neuralink  promises to revolutionise treatment for Parkinson's disease, epilepsy, spinal cord injuries, obesity, autism, depression, schizophrenia and tinnitus.

It could be used to control exoskeletons and prosthetics that could restore movement in individuals, and by connecting the human brain to a computer, individuals could potentially improve their memory, learning, and problem-solving abilities.


How Neuralink works?

Neuralink components -

Brain-Computer Interface (BCI) is made up of electrodes that are implanted into the brain, and a computer that processes the information received from these electrodes.

The electrode threads are made of a flexible polymer that is biocompatible, meaning that it can be safely implanted into the brain without causing any harm.

N1 chip

It is a custom-designed chip that acts as a translator between the human brain and the computer. It can process vast amounts of neural data in real-time and provide feedback to the user. 

The surgical procedure

1)The first step of the procedure involves the surgeon making a small incision in the scalp, exposing the skull. Next, a small hole is drilled into the skull, through which the robot will insert the electrodes into the brain. 

2) Once the electrodes have been inserted, they are connected to a small device located behind the ear. This device is responsible for transmitting signals between the electrodes and an external device, such as a computer or smartphone

Status of Neuralink 

As of May 5, 2025, Neuralink has successfully implanted brain-computer interfaces in three humans. The company is focused on restoring autonomy to individuals with paralysis, including controlling computers and mobile devices with thoughts.

Neuralink is also working on vision restoration with its "Blindsight" device, aiming for first human implantation by the end of 2025. 

Neuralink's speech restoration device has been granted Breakthrough Device Designation by the FDA, May 2, 2025. This designation aims to expedite the development and review of the device, making it potentially available to patients sooner.

Sixth Sense

Image
Sixth Senses  Sixth sense (ESP extra sensory perception)is a power of perception beyond the five senses.  It is an inner sense of guidance that can help you navigate your way through life, to better relationships, health, well-being, and success. It is a cumulative power of all your other senses - sight, sound, taste, touch, smell - that culminates in a stronger sense of inner knowing.

Neurodivergence - Mental illness or Mad Scientist?

Neurodivergence -  Mental illness or Mad Scientist? Who Is Neurodiverse/Neurotypical? The terms "neurodivergent" and "neurodiverse" refer to people whose thought patterns, behaviors, or learning styles fall outside of what is considered "normal," or neurotypical of humans. The concept of neurodiversity is not necessarily disabilities. Some differences can be real strengths. Who are Neurodivergent? The neurodiverse population includes people with specific diagnoses that are considered developmental disorders (as opposed to intellectual disabilities or mental illnesses). These include but are not limited to: Autism : A developmental disorder that includes differences in social communication skills, fine and gross motor skills, speech, and more Attention deficit hyperactivity disorder ( ADHD ): A neurodevelopmental disorder that includes features of inattention, hyperactivity, and impulsivity Tourette's syndrome : A tic disorder that starts in childhood ...
