Neuralink makes history with a less invasive surgery.

Successfully Performed First Human Transdural Procedure

In a surgical breakthrough that has redefined the boundaries of neurosurgery and medical robotics, Neuralink successfully performed its first human transdural procedure at Toronto Western Hospital. This robot-led operation eliminated the need to remove the brain's protective membrane to implant the company's famous chips. Less than an hour after the procedure concluded, the patient was already controlling computers with their mind.

Traditionally, implanting brain-computer interfaces requires a durotomy—a manual, highly invasive process in which surgeons cut the dura mater (the biological armor of the cortex) to gain direct visibility. By bypassing this critical step and inserting the filaments directly through the intact membrane, Neuralink applies industrial production philosophy to medicine: eliminating unnecessary steps to make the procedure faster, repeatable, and infinitely safer.

The greatest challenge is purely mechanical.

The dura mater is significantly tougher than the ultra-fine filaments implanted by Neuralink; to penetrate it without bending the needle or damaging brain tissue, engineers completely redesigned the insertion system. The robot was equipped with a needle geometry capable of withstanding greater forces, while hundreds of tests were conducted on synthetic membranes developed to accurately replicate the mechanical resistance of the human dura mater.

The entire insertion process is now controlled by algorithms that continuously adjust force, speed, and depth to minimize friction during penetration. However, piercing the membrane solved only part of the problem; since the brain remained hidden, the robot needed to identify blood vessels—invisible to it—before beginning each insertion. To achieve this, the system uses indocyanine green fluorescence angiography; simply put, this involves a contrast agent introduced into the patient's bloodstream that becomes visible when illuminated by infrared light.

The robot's cameras capture this glow through the dura mater itself, producing an extremely precise vascular map. Using this information, the artificial intelligence automatically calculates trajectories that avoid major blood vessels, significantly reducing the risk of bleeding. However, the brain never remains completely still; every heartbeat and breath causes slight shifts in the brain's surface. To compensate for this continuous movement, Neuralink incorporated optical coherence tomography (OCT) into the robot.

Using infrared light beams, the system generates three-dimensional images at microscopic resolution and tracks every pulsation of the brain in real time; this allows the robotic arm to synchronize filament insertion with the safest possible moment, automatically correcting for movements that are virtually imperceptible to the human eye. This breakthrough represents far more than a mere technical improvement. By combining computer vision, high-resolution optical imaging, artificial intelligence, and precision robotics, Neuralink demonstrates how neurosurgery is moving toward procedures that are increasingly automated and minimally invasive.

While it remains necessary to monitor clinical outcomes and the progress of studies to confirm the benefits of this approach on a large scale, the direction is clear: the future of brain-computer interfaces will rely less on the hands of a human surgeon and more on the precision of robotic systems capable of seeing, calculating, and operating at a scale beyond human capability.

I know this is a highly controversial topic, but tell me: if this technology could enhance your reasoning and memory capabilities, would you let a robot drill into your brain to implant the chip?
