Cannibal Worms


A distinction in this respect should certainly be made between short-term and long-term memory. It has been suggested that the former offers certain analogies with the workings of a digital computer, where familiar pathways can be reactivated or re-excited or in such a way as to constitute a residual record of past activity. The latter, on the other hand, must be physically embodied in some way, since it can endure for almost a hundred years, surviving comas, shock treatments, and even (in the case of experimental rats) refrigeration. An accidental concussion will often take away the memory of the hours immediately preceding it. It therefore seems probable that short-term memory is the more readily interrupted, being embodied in connections which must continually re-excite themselves[*] to last. If they do prove durable, such memory chains are (somehow) transferred to long-term storage, perhaps embodied by a literal “growth” within the synapses.

Short-term memory requires excitement

Memory itself, or the information it encodes, takes the form of connections, not of molecules. The quest for the biochemists’ holy grail, the so-called “memory molecule,” is therefore a mistaken one. Some researchers have tried to pass on memories by injecting extracts from schooled brains, or by encouraging cannibalism in worms.[+] Brains can indeed be altered chemically by injection, but specific information transfer has never been unequivocally documented. Fantasies of cannibalism appear to be more psychologically than biologically coded.[#]

Long-term memories transferred by cannibalism

Cicero, Marcus Tullius (106-43 BC)


Now, as in Tullias tombe, one lampe burnt cleare,
Unchang’d for fifteene hundred yeare,
May these love-lamps we here enshrine,
In warmth, light, lasting, equall the divine.
[J. Donne, Poetical Works, p. 125]


After the death of his daughter Tullia in 45 BC, the celebrated Roman lawyer, orator and statesman retreated from public life.[*] When her tomb was excavated in the Renaissance, it is alleged that a single lamp was found still burning in the airless gloom.

Fun to be thirsty










Critias


Plato’s description of Atlantis (the plain and the mountain):

Looking towards the sea, but in the centre of the whole island, there was a plain which is said to have been the fairest of all plains and very fertile. Also in the centre of the island, there was a mountain not very high on any side. In this mountain there dwelt one of the earth-born primeval men of that country, who had an only daughter who was called Cleito.[*] The maiden had already reached womanhood, when her father and mother died; Poseidon fell in love with her and had intercourse with her, and breaking the ground, inclosed the hill in which she dwelt all round, making alternate zones of sea and land larger and smaller, encircling one another; there were two of land and three of water, which he turned as with a lathe, each having its circumference equidistant from the centre, so that no man could get to the island.

NB: Circles of land and water:

They arranged the whole country in the following manner:

First of all they bridged over the zones of sea which surrounded the ancient metropolis, making a road to and from the royal palace.

Then, beginning from the sea, they bored a canal of three hundred feet in width and one hundred feet in depth and fifty stadia in length, which became a harbour, leaving an opening sufficient to enable the largest vessels to find ingress.

Moreover, they divided at the bridges the zones of land which parted the zones of sea, leaving room for a single trireme to pass out of one zone into another, and they covered over the channels so as to leave a way underneath for the ships.

All this, including the zones and the bridge, they surrounded by a stone wall on every side, placing towers and gates on the bridges where the sea passed in.

[Plato, ‘Critias’, Collected Dialogues, pp. 1218-22]

Am I the only one to see it sounds like here?
