  New Study Finds Axons May Resemble 'Strings of Beads' Instead of Smooth Lines

  A recent study challenges the traditional view of axons as smooth, cylindrical fibres, revealing they may actually resemble "strings of beads" or nanoscopic varicosities. Conducted by researchers at Johns Hopkins University using a high-pressure freezing imaging method, the discovery showed rotund blobs connected by thin tubes within axons. These s...

  Researchers Develop Cell-Level Wearable Devices to Restore Neuron Function

  Scientists at MIT have developed groundbreaking cell-wearable devices that mimic natural myelin to treat neurological disorders like multiple sclerosis. These micro-scale devices wrap around neurons and restore disrupted electrical signalling. They are battery-free and activated by light, allowing for non-invasive monitoring and modulation of neuro...

  Bionic Limbs Controlled by Brain Signals: A Leap Forward for Amputees

  Recent advances in bionic limb technology have transformed prosthetics for amputees, enabling control through brain signals. A clinical trial demonstrated the agonist-antagonist myoneural interface (AMI), which reconstructs muscle pairs to enhance control and perception. This approach allows for more natural movement and feedback, significantly imp...

  Monkeys Study Uncovers Science Behind 'Choking Under Pressure'

  A recent study published in the journal Neuron reveals insights into why both monkeys and humans struggle under pressure. Researchers found that stress impairs brain signals crucial for movement execution when faced with high rewards. The study, involving monkeys completing tasks for water, demonstrated that performance declined when potential rewa...

  Neuralink Brain Chip Implant Wires Now Stable in First Patient, Musk Hopes for More Human Trials This Year

  Neuralink's first brain chip implant in a human has stabalised, company executives have confirmed this week. The device works by using tiny wires, which are thinner than a human hair, to capture signals from the brain and translate those into actions such as moving a mouse cursor on a computer screen.

  Would You Let Elon Musk Implant a Device in Your Brain?

  With Neuralink’s device, a robot surgically inserts a device into the brain that can then decode some brain activity and connect the brain signals to computers and other machines. A person paralyzed from the neck down, for example, could use the interface to manipulate her physical environment, as well as to write and communicate.
