Quotes About Memory

Knowledge emerged about synapses, neurotransmitter-ology was born, and this idea was modified—a new memory requires the formation of a new synapse, a new connection between an axon terminal and a dendritic spine.

The evolutionarily ancient central amygdala plays a key role in innate fears. Surrounding it is the basolateral amygdala (BLA), which is more recently evolved and somewhat resembles the fancy, modern cortex. It's the BLA that learns fear and then sends the news to the central amygdala.

We don't passively forget that something is scary. We actively learn that it isn't anymore.

Suppose a major traumatic stressor occurs, of a sufficient magnitude to disrupt hippocampal function while enhancing amygdaloid function. At some later point, in a similar setting, you have an anxious, autonomic state, agitated and fearful, and you haven't a clue why—this is because you never consolidated memories of the event via your hippocampus while your amygdala-mediated autonomic pathways sure as hell remember. This is a version of free-floating anxiety.

It's not until the non-NMDA has been stimulated over and over by a long train of glutamate release, allowing enough sodium to flow in, that this activates the NMDA receptor. It suddenly responds to all that glutamate, opening its channels, allowing an explosion of excitation. This is the essence of learning.

So oxytocin is central to female mammals nursing, wanting to nurse their child, and remembering which one is their child.

Neuropsychologists are coming to recognize that there is a specialized subset of long-term memory. Remote memories are ones stretching back to your childhood—the name of your village, your native language, the smell of your grandmother's baking. They appear to be stored in some sort of archival way in your brain separate from more recent long-term memories. Often, in patients with a dementia that devastates most long-term memory, the more remote facets can remain intact.

Axonal remapping in blind or deaf individuals is great, exciting, and moving. It's cool that your hippocampus expands if you drive a London cab. Ditto about the size and specialization of the auditory cortex in the triangle player in the orchestra. But at the other end, it's disastrous that trauma enlarges the amygdala and atrophies the hippocampus, crippling those with PTSD. Similarly, expanding the amount of motor cortex devoted to finger dexterity is great in neurosurgeons but

This is the essence of learning. The lecturer says something, and it goes in one ear and out the other. The factoid is repeated; same thing. It's repeated enough times and—aha!—the lightbulb goes on and suddenly you get it. At a synaptic level, the axon terminal having to repeatedly release glutamate is the lecturer droning on repetitively; the moment when the postsynaptic threshold is passed and the NMDA receptors first activate is the dendritic spine finally getting it.

I can speak these words and perhaps you can see these things clearly because you are using your imagination. But I cannot imagine these things because I lived them, and to remember them with the vividness I know they should have is impossible. They are lost to me.

the man you watched die yesterday doesn't exist today; he fell to yesterday's bullets and you've got today's bullets to deal with. Nevertheless, sometimes it got me to brooding.

who no doubt honored a keen memory as a sign—bogus though it was in and of itself—of intelligence:

The Friend of Your Youth is the only friend you will ever have, for he does not really see you. He sees in his mind a face which does not exist anymore, speaks a name which belongs to that now nonexistent face but which by some inane and doddering confusion of the universe is for the moment attached to a not too happily met and boring stranger.

When one is happy in forgetfulness, facts get forgotten

Were we happy tonight because we were happy or because once, a long time back, we had been happy? Was our happiness tonight like the light of the moon, which does not come from the moon, for the moon is cold and has no light of its own, but is reflected light from far away?

The Friend of Your Youth is the only friend you will ever have, for he does not really see you. He sees in his mind a face which does not exist anymore, speaks a name, which belongs to that now nonexistent face but which by some inane and doddering confusion of the universe is for the moment attached to a not too happily met and boring stranger…the Friend of Your Youth is your friend because he does not see you anymore.

If the human race didn't remember anything it would be perfectly happy.

I did not understand my complex of feeling. Particularly as she was saying, 'Yes, I'm sorry I ever met you. Ever. If I hadn't I wouldn't have to go through this Awfulness, the awfulest part being that I'll remember you. Always.' — Robert Penn Warren, from "Goodbye," Uncollected Poems 1943-1989, The Collected Poems of Robert Penn Warren , ed. John Burt (Louisiana State University Press, 1998)

The past exists only in our memories, the future only in our plans. The present is our only reality. The tree that you are aware of intellectually, because of that small time lag, is always in the past and therefore is always unreal. Any intellectually conceived object is always in the past and therefore unreal. Reality is always the moment of vision before the intellectualization takes place. There is no other reality.

The past exists only in our memories, the future only in our plans. The present is our only reality.

The past exists in our memories, the future only in our plans. The present is our only reality. The tree that you are aware of intellectually, because of that small time lag, is always in the past and therefore unreal. Any intellectualy conceived object is always in the past and therefore unreal. Reality is always the moment of vision before the intellectualization process takes place. There is no other reality." ~ from Zen and the Art of Motorcycle Maintenance

You have embodied on Earth at this time to heal by awakening consciously to the memory of yourself as soul. Your healing comes and is completed when you see the light of your soul and know that light to be who you truly are.
