Neuralink's Technology Explained
Neuralink's brain-computer interface technology aims to connect the human brain directly to external devices. The system uses a small implanted chip and electrodes to read and interpret neural signals.
Understanding Brain Implant Devices
Brain implant devices create a direct communication pathway between the brain and external technology. These devices typically consist of a small chip implanted in the skull and thin electrodes that extend into the brain tissue.
The implants are designed to be minimally invasive while still providing high-resolution data on brain activity. Advanced materials and miniaturization allow for smaller, more powerful devices.
Role of Electrodes and Neurons
Electrodes in brain implants detect the electrical signals produced by neurons. These tiny sensors pick up the voltages generated when neurons communicate across synapses.
The electrodes are placed in specific areas of the cortex depending on the intended function. For motor control, they may target regions involved in movement planning and execution.
Artificial intelligence algorithms then interpret these neural signals, translating them into commands for external devices or computers.
