[@whoaminow100]

they left out that octopuses can teach other octopuses. there was a study to see how well octopuses could remember mazes. the old food is at 1 point maze with repeated attempts and timed. first time the octopus carefully explored the whole place ate the food when it got there and continued exploring until it was removed. second time it checked out the maze a little and went straight to where the food was. the next time they used a different octopus that was kept in the same tank, it went straight to where the food was. so octopus 1 told octopus 2 what was going on and where the food would be in a maze that octopus 2 had never been to.

Our bodies work like a monarchy and the octopus works like a democracy?

[@listen2164]

To add on to the analogy you've suggested; the human/chordate brain is relatively the same kind of brain organisation as earlier bilateria from before the protostomes and deuterostomes split. animals like the acoela and relatives (xenoturbella, nematomorpha) display a basic nervous system. acoels have the most primitive, basal level of cephalisation, but the only thing they have in that regard is the rudimentary brain, like the thane of a simple feudalistic system, with a nervous net, the disorganised society, just starting to become organised.

[@listen2164]

octopuses have an "oligarchic" brain, to continue the analogy, though their 8 nerve cords, complete with their own brains, come from their earlier molluscan ancestors, and with the majority of their fellow protostomes. the nerve cords are ventral, like in planarians, and, common to all protostomes, a dorsal brain; whereas most deuterostomes, including us, echinoderms (for a tiny point in their early larvae) have a medial (centred instead of dorsal or ventral) brain and a dorsal nerve cord, which becomes the spinal nerve cord. we continued to develop the same basic monarchic nervous system, and octopus developed from the same vague monarchic nervous system but unlike most other molluscs, even squid and cuttlefish, are the most truly different in their democratic/oligarchic nervous system. earthworms would technically almost be diarchic, with one brain in the front and a secondary rear cerebroid ganglion with three-quarters of the same level of autonomy as the earthworm's cerebral brain

[@somanautics]

In spite of what Claudio L. Guerra (who wrote this lesson) teached us, the human somatic nervous system (SNS or voluntary nervous system, the system of voluntary movements through the skeletal muscles) behaves exactly like the octopods' brain. SNS also has a behavioral library from which it selects behavioral responses: when we have an intention, as the signal travels through the network, the SNS pickup the message and jump into the action to command the movement selected from the library which is selected in its wholeness, not moving the individual parts. To be clear, when we decide to grab an apple, the SNS selects the entire packet of answers for grabbing the apple based on the information collected at that moment from various channels, for example the distance between the body and the apple. These are clearly discoveries only from the early 2000s thanks to functional neuroimaging techniques, but as early as 1900s scientists such as Moshé Feldekrais speculated this and created movement educational methods based on this principle of our nervous system and that's why in motor rehab experts don't work only on the individual bodyparts but on the whole functions (to grab the apple in our case)! :) Anyway this is an exellent lesson, thanks you TED-Ed!

[@harmonyjones8035]

It's octopuses. Octopi gets a red line under it and my spellchecker looks at me like I'm a bonehead :)

[@contramuffin5814]

OP, that's why there's significant debate over the plural of "octopus." While general notion is that "-us" words becomes "-i," you have to realize that English is perhaps one of the most stupid languages ever conceived, with exceptions to the exceptions of rules of English. Some linguists therefore argue that because octopus has a Greek etymology, it doesn't follow the "-us to -i" rule, which applies to Latin words, making "octopuses" the correct word in this sense.

[@hasch5756]

Neither does Cactus, actually. The Greek plural form would suggest something along the lines of 'Cacteae'
