I asked a similiar question, in short, ribosomes start of in the cytosol, when translation starts a subpopulation of those ribosomes will move to the ER. by CharonY

I would highly recommend reading up a little further... It is very important that you at least understand the basic mechanisms of memory before going off and trying to figure out how to do something that no one (as far as I know) has been able to do. I don't really agree with this article, yes the brain isn't a computer, but information IS stored in the form of a complex network of neuronal connections. And when we adjust such information, those connections have to be changed or a new pattern is produced and the old one is (partially) discarded. I have no evidence for that last part (what happens when we adjust information, but I feel those are the two options we have). The article describes that a newborn baby isn't born with data, but mentions reflexes and specific behavior. How is that not a form of data? I don't really understand the context of the article (in the end it seems a introduction to computing?), but on it's own I would say that while brains are certainly not computers, memory is stored in some form inside your brain. Additionally, things like the Default Mode Network (DMN) and other constant pathways do seem to at least on the face seem to imply some type of processing (but what it seems to me, definitely isn't truth). -Dagl

I wasn't very sure if what you said was true (cause it sounds very... broad;p) so I checked for a source, turns out that you are right and low frequency stimulation does seem to enhance episodic memory! https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00993/full Quoted from the conclusion: The findings of the meta-analysis on younger adults revealed that frequency interacts with MTI as well as with stimulation timing. Specifically, both online and offline 1 Hz rTMS led to enhancing effects, which was driven by below-MTI stimulation. In addition, offline 20 Hz rTMS had enhancing effects whereas, online 20 Hz rTMS and 20 Hz rTMS at below-MTI led to impairing effects on episodic memory. A systematic review of the older adults and those with clinical disorders revealed a similar pattern of enhancing and attenuating effects of rTMS on episodic memory performance. However, important differences did arise with older adults and clinical populations implementing both offline 5 and 10 Hz rTMS protocols that had enhancing effects on episodic memory.

Could you clarify what you mean by cellular assemblies? And could you explain the relevance of the hippocampus? I could be wrong, but it seems you have just grasped the surface of brain signalling/memory formation and you may have some overly simplified ideas. Synaptic plasticity seems to be, at least for a big part, responsible for adaption. Basically (this is highly oversimplified, see resources at the end), every thought or idea is (probably) represented by 1 or more (no reason there cannot be redundancy) networks of many neurons. Each neuron has many many connections (synapses) and these can all be adjusted (more or less likely to fire at a given signal, or a stronger/weaker signal when firing). When you memorise something, you consistently activate the group of neurons that represent that concept. More specifically, you activate THOSE synapses, not other synapses (as much). This leads to strengthening of those connections, making it easier to fire that specific pattern (concept) the next time. The Principles of Neural Science by Kandel is an amazing text book to go through. If you want some more specific articles: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3514210/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367554/ https://onlinelibrary.wiley.com/doi/full/10.1111/j.1460-9568.2010.07344.x If you can't access some, remember that sci-hub is a thing. There is some evidence for signals to loop around inside the hippcomapus a few times, but I can't find the reference (nor can I find it in my notes). Hope this helps. Another paper discussing synaptic plasticity and counterarguments: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6212519/ Another one by Kandel (just like the book and first article): https://www.cell.com/cell/fulltext/S0092-8674(14)00290-6
