Finding Hard To Recall Your Dreams? Now Simply Record Them
Wouldn’t it be nice if someone could record your dreams, your
fantasies and superb ideas that strike your sub-conscious mind? Your wish would
soon be fulfilled. According to a new research, we can now record our dreams
and thoughts that come in our sub-conscious mind. Scientists believe that
development in this technology would allow us to read others’ thoughts too.
Three (3) researchers from university of California, Berkeley
participated in this experiment. They entered a functional MRI (Magnetic
Resource Imaging) system. These three subjects were made to watch two different
Hollywood movies trailers while the machine recorded their blood flow through
the brain’s visual cortex, the part of the brain that process visual
information.
The readings of the machine were fed as input to a computer program
which converted these readings into three-dimensional volumetric pixels called
voxels. The brain signals generated by moving pictures are decoded by this
process. In this experiment, a computer program was made that learnt the
association of brain activity with the visual patterns in the movie while the
subjects watched the first set of clips. Then the other set of clips tested the
movie reconstruction algorithm. This computer program was made to analyze 18
million seconds of random YouTube videos. Thus a huge database was created for
the potential brain activity. From this huge database, the computer program
selected the one hundred clips that were almost similar to the ones watched by
the subjects.
This computer program mimics our brain. When we see a yellow flower,
our brain tries to match this yellow color with the different shades of yellow
color available in our memory. Similarly this computer program compares the
brain reactions with the huge database of 18- million-second videos and picks
up the clips that are most similar to the brain reactions. These clips are then
merged into a video. This new video is almost similar to the original video
clip that the subjects watched. Thus, bigger the database of videos
repositories and higher the computing power, the better would be the results.
This experiment is being considered as a major break-through in the
history of computer science and biology. The neuroscientist Jack Gallant
rightly stated “We are opening a window into the movies in our minds."
Scientists are also speculating that in coming decades, we would even be able
to read each other’s minds.
