Introduction

How do brain-computer interfaces (BCIs) work? These revolutionary systems link your brain directly to machines, enabling paralyzed patients to move robotic arms, gamers to control VR with their minds, and even telepathic communication. From Neuralink’s implants to non-invasive EEG headsets, BCIs are merging humans with AI—here’s how they function.

What Is a Brain-Computer Interface (BCI)?

A brain-computer interface (BCI) is a device that translates brain signals into digital commands. Think of it as a “Wi-Fi for your thoughts”—it lets you control technology without speaking or moving.

3 Types of BCIs

1. Invasive BCIs (e.g., Neuralink) – Surgically implanted for high precision.
2. Non-invasive BCIs (e.g., EEG headsets) – Read brainwaves through the scalp.
3. Partially Invasive – Less common, used in medical research.

📌 Example: A paralyzed man used a BCI to sip coffee via a robotic arm (Nature Study).

How Do Brain-Computer Interfaces Work? Step-by-Step

1. Detecting Brain Signals

BCIs use electrodes or sensors to capture:

• Neuron firing patterns (invasive BCIs).
• EEG brainwaves (non-invasive headsets).

2. AI Translates Thoughts into Actions

Machine learning decodes signals into commands like:

• “Move cursor left” → Controls a computer.
• “Grasp object” → Operates a prosthetic hand.

📌 Future Idea: Elon Musk predicts BCIs could enable telepathy by 2030.
