Decoding Brain Activity: Unraveling the Inner Workings of Thought
Introduction
Scientists have made significant strides in understanding how the human brain processes language. A recent breakthrough involves decoding brain activity patterns using functional MRI scans and artificial intelligence (AI). Rather than attempting to replicate every word, this system reconstructs the essence of what a person hears or imagines. Let’s delve into the fascinating world of neural language processing.
The Brain’s Semantic Landscape
Dr. Alexander Huth, a neuroscientist and computer science expert at the University of Texas in Austin, explains that this technology delves beyond mere words. It reaches the thoughts concealed behind language, tapping into semantics and meaning. By analyzing brain activity, the system deciphers the underlying concepts rather than focusing on individual words.
How It Works
- Functional MRI Scans: Researchers invited three participants to spend up to 16 hours inside a functional MRI scanner. These scans detect brain activity patterns associated with various tasks.
