How Cuttlefish’s Powerful Conservation Protects Old Age

Can you remember? what did you eat last week’s meal? This cessation is a function of small memory, and we are able to better remember the time and place of events that often diminish with age. Cuttlefish also appear to reflect the color of their memories, but unlike humans, their potential does not diminish with age, according to new paper published in Events of the Royal Society B..

“Cuttlefish can remember what they ate, where, when, and use this to guide their future decisions,” said co-author Alexandra Schnell of the University of Cambridge, who did this at the Marine Biological Laboratory in Woods Hole, Massachusetts. old age, even though it shows other signs of aging such as muscle weakness and hunger. “

Earlier this year, tinanena on a study by Schnell and colleagues to show that cuttlefish can delay happiness. In particular, they can transmit the popular cephalopod Stanford marshmallow test: wait a little longer for a favorite animal instead of being a very important animal. Cuttlefish also performed well on subsequent study tests – the first such link between self-control and intelligence has been found in non-mammalian species.

In this experiment, the cuttlefish had to choose between two animals: It could choose to eat prawn king immediately or delay the enjoyment of live grass crabs. The student can see all that he can do during the whole judging process and can stop waiting at any time and eat the king’s prawn if he gets tired and just grabs the crabs of grass.

The team also provided cuttlefish on a study project to review how they work consciously. The cephalopods began to study the combination of a visible sign with a special animal prize, and then the researchers twisted the existing ones so that the same prize was connected to another symbol. They found that all cuttlefish could wait for a better reward and tolerate delays of 50 to 130 seconds, similar to large hardy animals such as chimpanzees, crows, and parrots.

Recent research is looking at whether cuttlefish have some form of short-term memory — the ability to recall specific past events based on what happened, what happened, and when they happened. People develop this ability around 4 years, and our temporary memory decreases as we age. This is in contrast to mental memory, our ability to remember what we have learned without meaning of space and time. Psychological studies in humans have been shown to be impossible with old age.

The area of ​​the hippocampus in the human brain plays an important role in memory retrieval, and it is thought that its deterioration over time leads to a temporary decline in our memory as we age. For a long time, scientists thought that short-term memory was only human because the memory of these memories is linked to cognitive memory. People can express this in words; it is very difficult to assess what can happen and identify the animal (in a human way) animal.

However, several species have been shown to show similar ability to “episodic-like” terms that local scientists use to “explicitly acknowledge that we are not talking about human language and time-sensitive information,” according to Schnell et al. wrote the footnote. For example, 1998 survey found that jay birds can remember the time and place of the food storage and what it was like. Characteristics of temporary memory recurrence have also been observed punch, very monkeys, rats, and zebrafish.

Evidence for episodic memory is also shown in freshwater fish. The Cuttlefish do not have a hippopotamus, but they do have a well-developed brain system, which has a straight-lobe that resembles a connection to the human hippocampus function – for example, learning and memory. Previous research has shown that cuttlefish have a strong future and are able to improve feeding activity and remember details of what, where, and when from past fatigue — which they also remember as memory-shifts their thinking depending on how the animal changes.
