Do octopuses dream? Brain recordings provide the first clues

When octopuses sleep, strange patterns sometimes flicker across their skin. Now, neuroscientists have been able to peer into the brain of a sleeping octopus for the first time - and explore this strange sleep state. They find remarkable similarities to the way that humans and other vertebrates sleep, despite the millions of years of evolution separating the two groups.

This is extremely fascinating! Octopuses have brains that are so alien, so different from ours. And yet they seem so familiar in so many ways.

@Spearca 10 месяцев назад

I imagine anything with a brain and a sleep cycle will dream.

I hope those little guys get released after their sleep study 😥

Yes I'm sure the Japanese researchers will trEAT them very well after the study

For the sake of scientific honesty, the answer is no they do not. Getting this data requires invasive procedures.

Makes the fact that there are companies out there, wanting to farm and slaughter masses of octopuses even more sickening. Thank you for uploading, this is truly fascinating.

As someone just beginning to study neuroscience, seeing the convergent evolution of REM(esque) sleep in other intelligent creatures (especially ones so neurologically distinct from humans) is so fascinating and awesome! It looks like this system really is uniquely useful for helping living beings -- it wasn't a fluke.

@heartofdawn2341 10 месяцев назад

Octopuses have developed intelligence independently of creatures like us, so it's not a surprise if they have developed dreaming as part of it. It may even be a necessity.

@unvergebeneid 10 месяцев назад

If it weren't a necessity, why wouldn't you be surprised they developed dreaming independently? Convergent evolution only happens if there are the same evolutionary pressures and only a very limited number of solutions.

@christopherclarke4480 10 месяцев назад

Fascinating!

@4coolclips 10 месяцев назад

Wonderful and Amazing!!! The flashes that travel across the skin almost look like a processing mechanism? Maybe like the way our eyes go side to side during REM sleep?

@alinowow 10 месяцев назад

i love this! I have a genuine question. How do we know it's an active period of sleep, instead of the octopus waking up for a minute, if it's so similar to the awake state?

@aditipophale 5 месяцев назад

Great question! Sleep is distinguished from other behavioural states by rapid reversibility (that is, the ability to wake up, quickly), decreased response to stimulus and homeostatic regulation (an increase in sleep after deprivation). We tested these criteria and found that the octopus was asleep while doing these patterns!

@FHBStudio 10 месяцев назад

Sleep, or dreaming specifically, may be older than the earliest common ancestor of cephalopods and mammals. Or it's convergent evolution.

If the intelligence of octopi interests you, then you should know about the Spanish company, Nueva Pescanova, currently setting up to be the first operation in the world to farm these highly intelligent beings for food in a high-volume indoor facility.

@HelicopterDown 5 месяцев назад

It's incredible that this could be the first physical portrayal of a dream ever discovered

@haemse 3 месяца назад

Has anyone looked at the changing sequence of the patterns with a high speed cam? Does the propagation correlate with the locations of their very distributed brain network?

@footfault1941 10 месяцев назад

Does that suggest like a REM sleeping? Anyway, detection of similar patterns of brain activity (inactivity?) is fascinating! OK, octopus passed. Next, do androids dream of electric sheep?

@AgnaktoreX 10 месяцев назад

Vertebrates sleep, spiders sleep, octupusses sleep. Which animal does not?

@unvergebeneid 10 месяцев назад

If there's REM sleep in spiders, that's news to me.

@mikeomolt4485 10 месяцев назад

Microbes? Bacterial? Deep ocean creatures where light never penetrates may have evolved an alternative to sleep.

Newer two religions of the world isolated animals from daily life whereas Ancient religions like Hinduism had and still have animal love animal reverence animal welfare even animal worship as part of their daily activities Don’t make fun of animal oriented ancient religions

Aramaic Bible in Plain English Holy Book of Genesis Chapter 1: Verse 24 And YAH♥️WEH said, “The Earth shall produce the LIVING SOUL with its genus, beast, and creepers, and the beast of the Earth with its kind”, and it was in this way.” Therefore; ABBA’S Living Breath = Living Soul Meaning the above has and is both an individual Spirit and Soul. As all animals and plants to the tiniest bacteria. If it crawls, walks creeps; as long as it has ABBA’S Living Breath ♾️ it has both

These octopuses should not be caged in a fucking lab. They should be in the wild, they're intelligent creatures. Human beings and their greed for knowledge.

@unvergebeneid 10 месяцев назад

... they type angrily into a product of human knowledge!

@FHBStudio 10 месяцев назад

Learning about animals helps us preserve entire species in the wild. If we don't know about them, it'll be harder to prevent extinctions.

@grafja 10 месяцев назад

You should be more upset about the Spanish company, Nueva Pescanova, that is setting up to be the first farmed octopus operation in the world.
