Octopus Memory

Octopodes are brilliant learners.

With a little imagination you can teach an octopus nearly any trick at all. A German agricultural expert in Samoa became curious about the flexibility of octopus. How small a hole can an octopus slither through? He set up an aquarium divided by a sheet of clear plastic. A glass tube connected the two halves of the tank. He put a crab in one, an octopus in the other. The Octopus saw the crab, quickly ran its tentacles over the Plexiglas wall, discovered the glass tube and slid through it to get the crab.

Smaller tube. The second time the octopus didn't waste time fiddling around. It immediately slithered through the glass tube. The researcher put in another plastic barrier with a smaller tube, and the octopus oozed through. Then a smaller tube until the hole was just about as small as the diameter of the octopus' eye. He made a movie of his octopus going through the glass tube and it looks like a pink worm with a big eye on one end.

The Seaquarium in Miami Florida had a display of Florida lobsters. The lobsters kept vanishing and the manager thought, perhaps, one of the employees was making off with them. Or maybe somebody was sneaking in over the fence at night and stealing them. The Night watchman himself was one of the suspects and was determined to catch the thief if only to clear himself. Again and again the lobsters vanished but he couldn't catch anyone doing it. One night he went about his rounds as normal and then slipped back into the main display area and waited. After 30 minutes he thought he saw something happening in the lobster tank and he turned on all the lights. A big octopus was in the lobster tank. The watchman ran around to the walkway above the tanks and as he entered the area he saw the octopus lugging its captive lobster along the walkway, hell bent for its own tank. When they checked the octopus tank they found the empty shells of the stolen lobsters buried under the rocks. Octopus can obviously learn new tricks all by themselves.

Where do they store their memories?

Some memories are genetic, recorded in the large, complex DNA molecules found in every octopus cell. These tell the cells how to go from one fertilized egg cell to the billions of cells that form and are an octopus. They store important memories about how a baby octopus should crawl, swim, disguise itself, communicate with rainbows in its skin, mate, reproduce, lay eggs and protect them and die. These are tricks the canny octopus learned over the hundred million years or so it has been prowling the seven seas. Ancient memories.

Then there are very short term memories, such as the ability of a cell to remember conditions existing a fraction of a second before, so it can compare incoming perceptions with the prior condition and thus respond. These are erased almost immediately and involve changes in simple protein structures.

And there are memories that the octopus stores for its rather short (one year) life. The wonderful discoveries each octopus makes during its life are stored in some secret place, maybe in RNA scattered everywhere in the octopus body. They are not passed along to their young. octopus never get to see their own offspring. The female does not eat while guarding her eggs. She dies when they hatch out and swim into the sea.

Thought Transference

There are some very peculiar aspects to memories. Single celled creatures, like protozoa, or bacteria can be taught to respond to certain signals. When the cells divide, the progeny keep the recorded memory.

Interesting? Here's an even stranger example of molecular memory.

The ability to do all this remembering, especially genetic remembering, is stored in the DNA molecules. Take a colony of radiation resistant bacteria. Blast them with radiation until they fragment, keep blasting until their DNA molecules fragment. Mix. The bacteria, along with their DNA molecules reassemble themselves. 

How can this happen if the DNA is supposed to organize the construction of the bacterium? How does DNA, once fragmented, put itself back together again?

The miraculous radiation resistant bacteria are not unique, either. It seems all DNA can repair itself. 

Again, the system must have a kind of central organizing system to even know part of its coded information is messed up and, it must have some way of repairing the problem correctly and in sequence.

There is only one model that fits these events;

Memory is the result of the flow of information in specific patterns. 

It reforms into these patterns so long as the "concept" remains in the perception, memory, and response of some portion of the whole association.

And what's a Response?
