Hello
I am not an expert in this field but I am really hoping to understand as much as I can about the concepts described in my questions below. I might be using some improper jargon and expressions, so I apologize if some things are incorrect or confusing.
#1 Do all the neurons have the same expression of the DNA that they contain? (DNA is the same in all of them, right?) Do the neurons cells get instinct behaviors directly from the DNA that they contain?
#2 I suppose the behaviors that are learned (rather than instinctive) come from environmental stimulus and are expressed in combination with the pre-programmed genetic instinct. Also, I imagine that the learned behavior needs to happen a bunch of times through a given batch of nerve cells in order for the behavior to be remembered by the nerve cells' pathway that is being created. Is there a certain amount of times before this pathway becomes permanent? Does the pathway always stay more or less the same (since the same nerve cells would need to be stimulated, right?)? And is there a limit to how many different "stimuli"/"pieces of information" a give nerve cell can "transmit"/"hold" (I read somewhere it can be anywhere from 1000 to 10,000!)?
#3 Once a nerve cell "adopts" a learned behavior, and it becomes "permanent", can it ever "forget"/"discharge" it? Or does the "charge"/"information" stay in that nerve cell for the rest of the person's life? Or does it slowly "fade" until it totally perhaps eventually dissipates?
#4 I read somewhere that a new "batch" of nerve cells need to override an old, habituated, unwanted behavior, which actually never really "goes away", and merely stay "overridden", and can in fact return back if the new habituated behavior doesn't "hold-up". Is this true? And if it is, is this new "information" "stored" within the same batch of neurons, along the same pathway that held the "old" memory or is this a whole new batch of neurons, with a totally new pathway, with the "new" information somehow "overriding" the other neurons that hold/transmit the "old" behavior? (or both?)
Many many thanks!
