The amazing drastic changes in the 20th century have took all of us into a real shock!!!The things that can't be dreamt of even are happening in real...
Functional MRI Scanners have been used in research to determine the active areas of brain.Test subject looked inside the brain and performed the task of receiving letters from the brain.The question was- Is a particular brain region on or off??The research group used data from the scanner to find out what a test subject is looking at.The Researchers 'taught' a model how small volumes of 2*2*2 brain scans- known as voxels- respond to individual pixels.
The model was given prior knowledge about how each letter looked like.This improved the recognizing ability of the letters enormously.
The approach is similar to what we believe happens when we perceive our surroundings.The brain combines the prior knowledge with the sensory signals.For example: we can recognize lines or curves of a letter after we have learned to read.And this is what exactly the research group is looking for- models that show what all is going on in the brain.The hope is to improve the model to such an extent that they can be applied to working memory or experiences such as dreams.
In the further research they will be working on more powerful scanners.
Also a recent experiment in Japan shows that the brain scans can predict what you're dreaming about.The researchers have developed a brain decoding technique that can predict dreams up to 60% accuracy.
Let's wait and watch!!!!
