The paper, at least as shown here, [1] is vague about which results came from implanted electrodes and which came from functional MRI data. Functional MRI data is showing blood flow. It&#x27;s like looking at an IC with a thermal imager and trying to figure out what it is doing.<p>[1] <a href="https:&#x2F;&#x2F;archive.is&#x2F;650Az" rel="nofollow">https:&#x2F;&#x2F;archive.is&#x2F;650Az</a>

I want to see a cats POV when its startled by a cucumber (Youtube has lots of examples). A theory is that part of the brain mistook it for a snake. Also research on &quot;constant bearing, decreasing range (CBDR)&quot; where drivers may not notice another car&#x2F;cycle in a perfectly clear crossroads till its too late.&#x27;

I think it would be interesting to know if the viewer&#x27;s familiarity with the object informs how accurate the reconstruction is. This shows presumably lab-raised macaques looking at boats and tarantulas and goldfish -- and that&#x27;s cool. But presumably a macaque especially whose life has been indoors in confinement has no mental concepts for these things, so they&#x27;re basically seeing still images of unfamiliar objects. If the animal has e.g. some favorite toys, or has eaten a range of foods, do they perceive these things with a higher detail and fidelity?

It reminds of this research where faces monkey&#x27;s were seeing were recreated almost identically.<p><a href="https:&#x2F;&#x2F;www.bbc.co.uk&#x2F;news&#x2F;science-environment-40131242" rel="nofollow">https:&#x2F;&#x2F;www.bbc.co.uk&#x2F;news&#x2F;science-environment-40131242</a><p><a href="https:&#x2F;&#x2F;www.cell.com&#x2F;cell&#x2F;fulltext&#x2F;S0092-8674(17)30538-X" rel="nofollow">https:&#x2F;&#x2F;www.cell.com&#x2F;cell&#x2F;fulltext&#x2F;S0092-8674(17)30538-X</a>

I hope one day we can turn this on for coma patients and see if they&#x27;re dreaming or otherwise processing the world.

Maybe I missed this, but isn&#x27;t the underlying concept here big news?<p>Am I understanding this right? It seems that by reading areas of the brain, a machine can effectively act as a rendering engine with knowledge on colour, brightness etc per pixel based on an image the person is seeing? And AI is being used to help because this method is lossy?<p>This seems huge, is there other terminology around this I can kagi to understand more?

Big jump when we go from decoding what you’re seeing to what you’re thinking.
