Have Researchers Discovered Why Humans Are Smarter Than Animals?

According to a new study, human memories are not stored in patterns, like animal memories, but jumbled all together

Researchers have believed for fifty years that the hippocampus, the seat of memory storage in our brains, stores patterns of memories separately. That’s true in animals but not, it turns out, in humans, according to neuroscientist Rodrigo Quian Quiroga, “In contrast to what everybody expects, when recording the activity of individual neurons we have found that there is an alternative model to pattern separation storing our memories… Shockingly, when we directly recorded the activity of individual neurons, we found something completely different to what has been described in other animals. This could well be a cornerstone of human’s intelligence.” University of Leicester, “Human intelligence just got less mysterious” at ScienceDaily He found that, human neurons, by contrast, store all the…

What Neuroscientists Now Know About How Memories Are Born and Die

Where, exactly are our memories? Are modern media destroying them? Could we erase them if we wanted to?

At one time, neuroscientists believed that there must be a “seat” of memory in the brain, something like a room with a door marked Memory. They settled on two structures called hippocampi, on either side of the brain’s base. The illustration shows the the hippocampus of the right hemisphere (public domain). But memories turned out to have no fixed address. Neuroscientist Matthew Cobb, author of The Idea of the Brain (2020, excerpt here), tells us, But the hippocampuses are not the site of memory storage. Rather, these brain regions are the encoders and the routes through which memory formation seems to pass. The memories that are processed by the hippocampuses seem to be distributed across distant regions of the brain.…

Claim: Yes, you can upload your brain

Fine print: They might have to kill you first
In a recent piece, we looked at cognitive scientist Susan Schneider’s explanation as to why we couldn’t cheat death by uploading our minds to the internet. But some have made a career of marketing the idea Read More ›
