At atomic level, can someone clarify how memory is stored in the brain..
sa3 gave you a good answer. He/She is referring to synaptic transmissions of neurotransmitters between neurons. As to exactly "where" specific memories are stored, it's still not completely understood. You can google "Penfield" and "memory" if you want to read about some of the research that has been done in this area.What do you mean by making 'connection'?
'Where' is memory stored?
No. If a person had strongly bonded neurons I imagine they would express severe learning difficulties. The same would be true of someone who has weakly bonded neurons. Newborns have very plastic synapses (i.e. they are not bonded strongly) but over time the synapses become less plastic. It is thought this is important in learning, if you neurons were strongly bonded you would not be able to process input well at all.So would it be true that a person with good memory would have a better bond between neurons. If so, how can one improve his/her memory?
