Scientists have long been fascinated by the human grey matter, and recent studies have been able to shed some light on how we view the world. Scientists at UC Berkeley have used brain imaging and computer simulations reconstructed from neural data to show us how images are seen inside our brains.
The way that the researchers did this was to use functional magnetic resonance imaging (fMRI) and some complicated computer models to work out how our brains have processed visual data, and then reconstruct the images, or even videos that we have viewed.
So far the technology can only reconstruct the neural equivalent of what we have seen, but maybe someday soon it will be sophisticated enough to be able to reconstruct whole images and memories.
Imagine the usage of this technology to help those who have neural impairments, such as stroke victims, or those with degenerative neural diseases.
The researchers developed this technique by showing black and white images to participants while imaging their brain with the fMRI. They then compared the original photographs with the brain data, and they were able to build a way to recognise any image from how the brain responded.
This breakthrough paves the way for more amazing reproductions of images we only see inside our heads, such as dreams and memories, perhaps even one’s imagination.
Sounds like some amazing research. Maybe one day we’ll be able to say we uploaded ‘that amazing dream’ we had on YouTube.
