Checking biochemical remnants tracing short-term memory and the neural paths leading to it, found in the brain, eyes, ears, and nervous system of a murdered person. Of course, only in the case where the body is preserved and was found a short while after the murder.

Real-time not remnants, but actually works [pocmloc, Mar 31 2023]

It is known that rods and cones are chemically activated in ways that signal the brain, and it's hypothetically possible to discover which chemicals have been depleted. But it depends on the different kinds of eyes, the configuration of cones and rods, how efficiently that person's eyes work, the shape of the eye and parts thereof, and becomes impossible just a few minutes after death.

The linked page states it's usable in rabbits, that's a long way from debunking it.

Maybe original to the poster. If so, kudos.

The eyes themselves won't hold more than a last image, if that.
The visual cortex and associated visual memory might be able to someday be accessed post mortem though, depending on decay. [link]

3 months ago I was on my way to get medical treatment for my foot at Sheba Hospital when a man in the street waved me to a stop so as to let a truck pass by.

I realized that I can see his waving hand and hat and body and feet but not his face. Closing my left eye I noticed that I have a gray line across my right eye, obscuring anything that was there. I could see the shape of the obtrusion, across a "line of reading" with a round image to the right of it.

Upon arrival I was accepted to the emergency room and after checking my cognition, sent to the eye clinic where after many tests I clearly saw my retina displayed on a large screen with a puffed line across the middle and a circle on the side, signifying a "vascular insult" event, and possible death of neurons.

That was the reasoning behind this.

I humbly accept your criticism and thank A1 for the wp link.

a1, yes.

pocmloc, that's a link for my Eye Scan Cam idea. Not for this one. OK, went there and found out it was [jutta]'s link over there!!! Thanks jutta!

Well that makes sense, where else would I find such a cool link?

The doctors at the emergency room first wanted to see if I am in the middle of a brain event. After the nurse briefly checked me, one of the doctors on duty asked me some questions related to my long-term and my short-term memory, like what if I know my name and what day it is, and if I remember my relative's names.

He made a quick evaluation of my eyesight, showing me an eyesight chart, and asking if I see the ends of his extended arms, then asked me to describe the eye loss, and tell him, to the best of my knowledge, when it started and how it developed.

They then whisked me off to the eye emergency room, which is in a different building altogether.
