This topic is going to be mainly about 'Rapid Perception'. If you don't know what Rapid Perception is, the link below would explain it.
- http://www.redicecreations.com/specialreports/2006/08aug/slowtime.html I started to look into rapid perception because many animes include such abilities. - Accel World, where people can accelerate and manipulate their 5 senses, and increase their focus, awareness, and reaction speed tenfold. Doing so affects their perception of the world around them; Everything slows down around them, and they can react at their normal speed. - Fate Zero, where Kiritsugu Emiya possesses a similar ability called Time alter. He also mentions the world 'accel' in some of them. Example: Time alter - double accel ! There were more animes that had something to do with this, but I can't really remember. Anyways, what are your thoughts towards Rapid Perception? - Do you think it's actually possible? - What would you do if you had the ability to perceive rapidly? - Do you know anyone that has the ability to perceive rapidly whenever they like? - If you know more animes that mention anything about accel, or increased focus/awareness, list them. |

ZA WARUDO!!!
Ahem. No, it's not possible, as neurons can only fire so fast. The only way to have rapid perception is altering time so that it flows for you faster than it flows for everyone else. And of course, that technology is a ways off yet, and might not exist for hundreds of years. |

sorry but you got that wrong! Adrenalin bursts are known for exactly that increased perception slowing the events around you and allowing you to make decisions in a much shorter time than usual. its the fight or flight syndrome when someone has the adrenalin burst before an accident or other potentially harmful event and the body chemically reacts to boost perception and increase the chance of survival. its well documented and long proven as a biological fact. |

I've heard one report of a policeman who in the middle of a firefight mentally accelerated - so he claims - so fast that he could see the castings fly out of his gun in slow motion. However, we only have his word for that. Other than that, care to provide some links to these well-documented and long-proven scientific studies of yours? Please note that I'm not saying that some acceleration is possible, because our brains can process information faster than they currently do. What I am saying is that the brain's hardware means there is a limit to how much this can happen. The OP was asking about Accel World-style acceleration, which has two 'levels' of accel; ten times and one-thousand times. I simply do not believe it is possible that neurons and - in the case of spoiler[Physical Full Burst, muscles] - can be sped up a thousand-fold, just like you cannot run Skyrim on a 286 computer. The hardware isn't capable of it. If you can provide a scientific paper in a peer-reviewed journal which categorically states that acceleration levels of a thousand-fold are possible, then I'll believe you. |

I watched something on this, it was probably a documentry on the human brain, in moments of stress people can percieve things quickly and make fast decisions. What was found though was that the brain actually bypasses higher thought functions that allows people to make complex decisions. So while people could allow their brain to quicken up and percive things in like a slow motion, you would not be able to make very good decisions.

besides being too damn lazy to look yourself. you probably want Lenard Nemoy to host a show on it so you'll take it as fact?
try looking up the effects of adrenalin in biology texts kind of an obvious line don't you think? not like the thousands of studies on its affects aren't enough but you can also look up fight or flight. next time you say something can't be true and then couch it after as:"i meant not by this many times" say that and not "it can't exist" |

@DuskyPredator:
Assuming I understand correctly, in that case you wouldn't perceive time superfast but your subconscious would. So you could react quickly but would not be standing around having conversations.
No, I want you to back up your strong assertions with some actual proof. You're the one making the claim, it is on you to back it up. Besides, if it is really as "well-documented" and "long-proven" as you say it is, then you shouldn't have any problem finding evidence.
Given that I was specifically responding to the OP and he was specifically talking about Accel World, I didn't think I needed to. |

its a chemical reaction to danger. you perceive things as happening slowly: like just before the car your in is about to hit something. or as you pointed out the policeman seeing the shoot out as slow motion. you are in fact thinking much faster at the time. its unlikely that you'd say much beyond the most basic or ingrained utterance at the time because the instinctual part of the brain will be predominant at the time which is also part of the effect of adrenalin.

'Rapid Perception' is possible, but only to a small degree. dtm42 was right that there is a limit to how fast a neuron can fire. There is something called an 'absolute refractory period' that every neuron, both in the CNS (brain and spine) and the PNS (peripheral neurons) has. An absolute refractory period is the time after a neuron has fired in which, no matter how strong the stimulation, that neuron cannot fire again. A normal cycle of stimulation for a neuron lasts 4 milliseconds, though exceptionally strong stimuli can make it as short as ~1 1/2 milliseconds. This 'rapid perception' wouldn't be sustainable for extended periods of time though, as stimulating a neuron again before it is 'fully ready' is stimulating it before the RMP (resting membrane potential) has returned to normal. Long story short, it would throw off the voltage gradients and chemical gradients that let thought be possible. Give you a horrible migraine.
That'd be a really cool power though. Olympics, here I come!

I hadn't even thought about the individual neurons; I was just thinking in general terms of how fast nerve signals travel, both in the brain itself and the various organs providing sensory data. I've heard the figure of 400kph (250mph) being bandied about, so to increase consciousness ten-fold I would assume that you would need to increase nerve signal speed ten-fold too.
Of course, if neurons have a 'cooldown effect' before they can be stimulated again, then that is a major roadblock to increasing speed of consciousness and thought. Trying to increase speed even ten-fold (let alone a thousand-fold) would probably fry your brain and cause loss of consciousness. Anyway, thank you Tris8 for your illuminating post. |

The idea of accelerating nerve or body speed is familiar to the Japanese probably because the popularity of Cyborg 009. I think Cyborg 009 was the first example of an anime featuring accelerating device implanted in his body. The original manga started on 1964, the first theatrical anime was released on 1966, and TV anime show started airing on 1968. The Japanese Wikipedia page concerning the accelerating device stated that the first appearance of the accelerating device implantation in the literature was “Tiger! Tiger!” by Alfred Bester. Since it was translated to Japanese on 1958, Ishinomori might have read this before starting Cyborg 009. |

What I think you guys are referring to is a form of flight or flight response called Tachypsychia, or Tachy Psyche effect. It is well known among martial artists, police, military and pretty much anyone who becomes involved in violent encounters. Your perception of time is altered and events appear to slow down, tunnel vision is also a commonly reported effect. But remember it is only ones perception of time that is altered, not the actual speed at which events occur.
Check wikipedia if you like - http://en.wikipedia.org/wiki/Tachypsychia |

I played soccer (football for those outside of the US) when I was in elementary. A friend had kicked the ball from about twenty feet back and I just happened to turn to see it coming right at my head. It felt so slow, and it felt like a long while had passed before I even decided to stop watching it and move my head out of the way. Her kicking speed was clocked at 55mph in sixth grade, higher than several teachers and the ball was within feet of me when I noticed it. It's the only time I've ever felt like time had slowed down, but it did happen to me once. |
