Brain-Computer Interface: When can we enter with our thoughts? | By fábio Ferreira | Coinmonks | February 2025

Imagine that you can write an email, send text or control your computer just by thinking. This future vision is moving quickly to reality with the development of the brain-computer interface (BCI). BCI establishes direct communication between the brain and external devices, creating a revolutionary revolution of how humans interact with technology. But how close are we to the world we can enter with thoughts? Let’s explore the current state of BCI, their challenge, and when we can see a wide range of adoption.

BCIS captures and interprets brain signals at the core and converts it into commands of computers or other digital devices. This is usually done using the following:

• ElectroEncephalograpy (EEG): Non -invasive sensors placed on the scalp detect the electrical activity of the brain.
• Inc cell implants: A small electrode surgically implanted in the brain provides more accurate signal detection.
• Near -infrared spectroscopy (NIRS): Use light to measure changes in brain activity according to the oxygen level.

By analyzing these signals, BCI can identify patterns related to specific thoughts, such as the intention of moving the cursor or trying to choose a letter.
