Memory is stored in cells throughout the body, not just the brain (www.earth.com)

In this study, the scientists simulated the process of spaced learning by examining two types of non-brain human cells — one from nerve tissue and one from kidney tissue — in a laboratory setting.

These cells were exposed to varying patterns of chemical signals, akin to the exposure of brain cells to neurotransmitter patterns when we learn new information.

The intriguing part? These non-brain cells also switched on a “memory gene” – the same gene that brain cells activate when they detect information patterns and reorganize their connections to form memories.

So hold on a minute - does this mean there might be some truth to the whole “eat your fallen enemy to gain experience” thing? That’s wild.

No, because you're eating the flesh, so you're digesting it.

This is more relevant to organ transplants.

Apparently, it's a known phenomenon that some organ transplant recipients seem to inherit some traits and even memories of organ donors.

I was wondering if there is a link between cellular memory and how trauma is encoded into DNA?

I suppose that explains survival instinct

I wonder if that contributes to "muscle memory".

As if haven't know for a century that immune system has the ability to both form memories and problem solve, that rivals the brain. The body being able to adapt to external stimuli isn't anything groundbreaking.
