Turning the Eye into a Camera Sensor

What if in the future, the human eye itself could be turned into a camera by simply reading and recording the data that it sends to the brain? As crazy as it sounds, researchers have already accomplished this at a very basic level:

In 1999, researchers led by Yang Dan at University of California, Berkeley decoded neuronal firings to reproduce images seen by cats. The team used an array of electrodes embedded in the thalamus (which integrates all of the brain’s sensory input) of sharp-eyed cats. Researchers targeted 177 brain cells in the thalamus lateral geniculate nucleus area, which decodes signals from the retina. The cats were shown eight short movies, and their neuron firings were recorded. Using mathematical filters, the researchers decoded the signals to generate movies of what the cats saw and were able to reconstruct recognizable scenes and moving objects. [#]

Basically, the scientists were able to tap into the brain of a cat and display what the cat was seeing on a computer screen. Something similar was accomplished with humans a few years ago, and scientists believe that in the future we may even be able to “photograph” human dreams!

    And that was in 1999? What have they been doing in the last 12 years?!

    Photographing human dreams? holy 5H!T. Now if you are a practitioner of lucid dreaming then you might just be able to make the most amazing pictures ever!

    Wow! What are musicians and the law enforcement going to do if this actually happens? Confiscate our eyeballs?

    Nice, really nice.  Experiment on cats.  Humans are the garbage of the Earth.

    Is that your way of volunteering?

    That’s being cruel to that poor cat.

    Amazing and terrible at the same time.

    Once the process is bidirectional, then we have the makings for media experiences similar to those depicted in the movie Brainstorm, and Gibson’s SimStim.

    And like you Rio, I wonder how far they’ve taken this since the video was made. I’ve experimented with impressing musical signals on my optic nerves and it’s so easy as to be silly. If I can perform successful (well, flashes of light in sync to the bass notes) experiments at home, surely advanced research has done much more sophisticated work.

    Sure would like to get ahold of that video. Pretty sure the frames  son’t all make that man look like a wolf.

    The words “electrodes embedded in the thalamus”, perhaps?

    That’s OK. It was a mean cat.

  • Cat Lover

    Please stop experimenting using cats! This is sad to see. Poor cat!

    I’d like to see the humans put the head apparatus on themselves, & let’s see what happens! Animals don’t get to choose if they want to be experiment subjects, humans do. Please stop being cruel to animals!

    “Curiosity killed humans” :)) So, research is done. Have results been used anywhere for good? I’d love to know how the cat’s brain works, but do we have to physically get into the brain to know that? Eww… I believe as a human/humane race we are able to find better methods.
