From Neural Signals to Images: Meta’s Exciting Breakthrough on AI-based Brain Activity Decoding
Decoding brain activity has long been a holy grail of neuroscience. Being able to understand the intricate patterns of neural signals holds the key to unlocking the mysteries of the human mind. Traditional methods of studying brain activity, such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), have provided valuable insights but are limited in their ability to precisely decode specific mental processes. This is where Meta’s breakthrough in AI-based brain activity decoding comes into play.
Meta AI is working towards decoding image perception from brain activity.
Meta’s AI-based approach overcomes these limitations by directly decoding brain activity patterns from neural signals. By training deep learning algorithms on vast amounts of data, Meta’s technology can identify unique patterns of brain activity associated with particular mental processes. The system is entirely non-invasive and could have near-term applications for some.
Meta AI has unveiled their research on Oct 18th
The new system combines a non-invasive brain scanning method called magnetoencephalography (MEG) with an AI system.
“This AI system can be deployed in real time to reconstruct, from brain activity, the images perceived and processed by the brain at each instant.”
Today we're sharing new research that brings us one step closer to real-time decoding of image perception from brain activity.
