Unlocking the Mind: Translating Brain Activity into Text and Images

The concept of pre-crime, as seen in the movie Minority Report, is becoming closer to reality with breakthroughs in translating brain activity into text and images. This has raised ethical concerns about privacy and government control. Researchers at the University of Texas and Meta have made significant progress in this field by creating devices that can decode brain signals to capture the meaning and exact words of information.

Decoding Brain Activity into Text

โšก๏ธBrain signals can be decoded to capture the meaning and exact words of information.

๐Ÿง Different regions of the brain redundantly encode word-level language representations.

๐Ÿ”—Even if one brain region is damaged, others can process the same information, preserving language abilities.

Translating Brain Activity into Images

๐Ÿ–ผ๏ธThe system consists of an image encoder, a brain encoder, and an image decoder.

๐Ÿค–The AI was trained on a public dataset of brain recordings and learned imagery by itself through self-supervised learning.

๐ŸŒŒUsing this technique, the AI can interpret what participants were looking at and generate images similar to their visual perception.
