Make someone overreact So you swim to North Korea (hopefully the tank was not too far). Once there, you regroup in the shape of a submarine and you slowly approach any US/Japanese/Chinese/North Korean/South Korean warship you can find. Hope someone overreact and press the wrong button. If not, try again. Playing with nerves Also every time you see ...

Let's shut down and/or melt-down some nuclear power plants. Heck if some brainless Swedish jellyfish could do it in 2013, surely a gang of criminal salmon can manage!

This answer may be voted as non-responsive, but I think your question may be missing your point. You assert that "filtering out" the unimportant stimulus is a sign of slow or incomplete processing. Instead, I consider it to be a very high-speed approach to eliminating unimportant inputs and allowing the situational intelligence to focus on the unexpected,...

a machine that perfectly maps out the way in which neurons fire in Patient A regarding a certain memory, and then to stimulate an identical firing of neurons in Patient B, so as to allow them to live that memory or even believe it to be theirs? This can only work if the wiring of the neurons in our brain is standardized and homogeneous like the circuitry in ...

What harm can they do? Not much. They lack arms/hands and legs/feet. Their ways of communicating will be limited, and whatever they come up with according forcing them to work together to learn to communicate that will be some form of communication which works for the giants fish tanks they're being held in. Not a vast ocean. Besides, most species of ...

Few minutes (4 to 5) of anoxia (lack of oxygen supply) are sufficient to cause permanent damage to neurons, compromising a brain's functionality. https://www.spinalcord.com/anoxic-brain-injury On average, the brain can survive a mere four minutes without oxygen, so if you suspect a stroke or other injury that is cutting off oxygen to the brain, you need ...

A good example will be Octopus. The octopus (along with cuttlefish) has the highest brain-to-body mass ratios of all invertebrates; it is also greater than that of many vertebrates. It has a highly complex nervous system, only part of which is localised in its brain, which is contained in a cartilaginous capsule. Two-thirds of an octopus's neurons are ...

Reality check: Not Gonna Happen Keeping a brain alive is a rather trivial exercise and Brythan's answer provides two common modes of feeding people who can't feed themselves. It's a "trivial exercise" because TPN and G-Tubes are placed in living bodies whose metabolic functions are working properly. But Bill is looking to do something radically different ...

To "replicate such firing" is, as noted, impossible in 2 different brains. They are just too different. However, consider that right now, you are reading these words and my thoughts are becoming your thoughts. We have both spent years learning English in order that these formations of black and white pixels fire the correct neurons. This learning process ...

Well, I'm sorry to say, but the world as you know it, is in deeper trouble than you think. The fishes just need to follow a simple 2-step process. Step 1: Try to get back into a human body. Given that "The business of mind storage [has] become a profitable one", it would be fair to assume that the technology to do so would be fairly easily accessible. So ...

Falling down a K hole. It is hard to keep from responding to the world - especially if someone hurts you to see if you are faking. But it is a lot easier with drugs. Ketamine is used to achieve this state. https://www.verywellmind.com/what-is-a-k-hole-21861 Ketamine is a dissociative drug. In simple terms, dissociative drugs make users feel detached ...

Your super smart Salmon want to cause chaos so what they do is abduct highly aggressive species and forcefully migrate them into environments where they have an abundance of food and not many natural predators. Eventually the ecosystem in these areas are ruined leading to a collapse in the supply of seafood causing seafood prices to spike and the lack of ...

I think it's more than just the world the creature lives in you also need to account for their habits and the their place in the ecosystem to that end I believe you need to start with a warm-blooded obligate carnivore, such creatures are almost always on the hunt for the next meal as it is. Then you need to put them in the middle of the foodchain rather than ...

No, each person brain is different and the map from one will not produce the same results in another. Due to plasticity and how each brain is individually trained to your sensory organs and experiences each memory in each brain is unique. Each brain a has a unique map of connections called a Connectome. A perfect copy of someone else's memory would require ...

Scarcity of resources is a fact we have to deal with, no matter if we are someone with an IQ of 200 or an amoeba in a muddy puddle. From scarcity of resources follow an economy principle: you use something only if the cost is justified, else it is just a waste of scarce resources. So, for example, if you are an organism living in an underground lake, eyes ...

Retrograde amnesia is perfectly reasonable side-effect of the procedure itself. There would be considerable physical trauma to the brain from being removed and implanted. Hypoxia would be likely during the process. Blood circulation would almost certainly have suffered at several points. All of these can cause amnesia if they happen to relevant parts of the ...

Although L. Dutch's answer probably contains all the information you need, I think it would also be important to take into account the manner of the person's death. If an elderly person passes away in their sleep, I would guess that their memories would be readable for longer than someone who fell down a cliff and died of concussion, especially if they ...

This is basically what the brain already does, but ramped up to 11 and in control of the conscious mind. The problem is that this requires a very specific mind. During development your brain makes millions of connections with other parts of the brains, then at some point it starts to purposefully remove many of these, leaving the most used neural pathways ...

I think the key is to stop thinking like a fish....it offers them very few advantages. The only thing they should worry about as salmon is how to stop being salmon. Head to a touristy destination where people rent canoes or kayaks and make a coordinated effort to cause one of them to drop their cellphone. Many phones are waterproof to some reasonable ...

Shutdown the Internet Well, that is a unlikely action to be performed by salmons because of their lack of sharp whatever, but beside this most to all communication across the oceans is backboned by water-cables. While I still don't think that a salmon might be able to nibble through an intact water cable, at least they could give it a try. If that fails ...

I can't understand how should be possible that a brain can integrate with logical gates. ... But now, even newest working chips still operate with 0 and 1 and logical gates So do neurons. You might think your wetware is analogue, but nerves don't actually work that way. The magic phrase you need to know is action potential, possibly along with voltage-...

Your nervous system is more distributed than originally believed, but the degree to which this is true is still a bit uncertain despite it being a major point of study since the early 1800s. What is known is that the human spine contains the majority of your body's reflexive functions and motor memory effectively making your spinal cord part of a sort of ...

A less centralized nervous system is an anatomical feature seen in non-uplifted animals in real Earth. For example, insects have brains, but they also have neural ganglia distributed through their bodies. These ganglia are responsible for functions which in us are all processed in the head, such as locomotion and gut movements. And then there is the ...

Most of the information filtered out is next to useless. For instance, if you have ever seen "Tracers" in movies where they are showing people taking drugs, that's an actual thing, not a hallucination--your eyes do not have perfect resolution or response speed. When something moves in front of your eyes it takes a while to fade--your brain figured this out ...

Yes. But it’s going to take some backstory for me to explain. We don’t know the source of consciousness. There is a theory (based on data) that our brains have a quantum entanglement component that would make them un-copyable because you could never recreate the same entanglements. This theory says that once a mind is instantiated in any medium, that ...

If the technology is universal and memory sharing gets common, the solution is transparency. Instead of everyone keeping their own secrets to guard against unauthorized transactions, the sequence of events is kept largely public. You don't prove who you are by presenting proof of knowledge, since knowledge is no longer a proof by itself, but through others' ...

Your question seems more focused on the biochemical responses such as an adrenaline rush or "feeling horny" rather than on the more esoteric definitions of emotion which might include love, hate, envy, etc. With this understanding, the administration of hormones into the brain's blood supply would be governed by the AI of the cybernetic body. When the ...

You cannot trivially overclock a human brain. You are limited by various important things, including the speed at which signals propagate along axons, and the maximum signal pulse rate, limited by the refractory period of nerve cells. You'll need to increase both, and you'll need to increase them proportionally and throughout the brain so that the brain ...

Yes. Brain mapping is really complex but we're gradually making headway. A while back, I heard a TED talk about optimism and the thing is that they were able to make people more optimistic or pessimistic by interfering with very specific areas of the brain (More info). In order to do this, your dystopian government would need to map out every part of your ...

Searching for "How do they feed coma patients?" found this Quora post, which says that are two ways to feed a coma patient. One is a feeding tube to the stomach, but the other is ...they receive TPN (Total Parental [sic] Nutrition) which is carefully formulated by a pharmacist once blood work is performed each week or few days, etc. this is delivered ...
