Here are a bunch of videos to answer all sorts of questions about neuroscience: https://www.youtube.com/c/neurotransmissions/videos --- Quote from: ebastler on February 06, 2021, 11:48:55 am ---Reads like a thinly veiled "Let me brag about my claimed IQ" post... ::) --- End quote --- Which is a very "synthetic" benchmark anyways. Even just within the realm of electronics engineering, there are so many specializations that no single test can fully explore one's skills. --- Quote from: amyk on February 06, 2021, 02:33:07 am ---Biological brains are more like FPGAs, with self-reconfiguration. ;) Massively parallel but not fast at sequential tasks. --- End quote --- That basically means that unless there's a major brain defect, the potential intelligence at a given age probably doesn't vary much between individuals and it's really a question of how well the "programming" can use it. And what it's "optimized" to do, for that matter. |

The brain is analog and is not architected anything like a computer so I don't know how you'd ever really make this comparison. As someone else said, massively parallel and recofigurable but not really very fast. There are some things that computers really struggle at that are trivial even for a person of below average intelligence, like identifying spam from legitimate email or spotting recognizable objects in a complex image. Other things like solving mathematical equations a computer can do vastly faster than the most gifted human minds. A brain is not running code, it's not executing instructions, it's more like a fully analog FPGA. |

It's more like a 'CPU' that's variably integrated within RAM. And it surely multi-tasks, when at the same time as controlling sub-conscious things like heart rate, body temperature etc etc, it can decipher what we READ, or are reading at the same time as feel & react to stimulus like a mosquito biting, and interrupting voices being heard/comprehended! Is that a 'parallel' system, or are there equivalent 'processor' Interrupts, to pause and re-direct!! I've been recently reading about so-called 'Speed-Reading'. There is a delay while the brain has to control our eyes, to scan across words in a sentence. And our brain also luckily does not have to read the individual 'letters', as we are now accustomed to see each word as a 'Picture', and know what it is. The problem though, is that even if/when our 'brain' is correctly 'interpreting' the words it has stored, we are NOT necessarily RETAINING the information properly, when a certain speed of 'reading' has been crossed. (Proportionally). At that point, our 'brain' Flops, have Flopped!! :-X |

Neurons have variable response, as far as I know they are not either on or off like a digital bit and the brain doesn't really deal in numerical values natively. There are no discrete brightness steps the eye can detect for example, the more photons hit the receptor cell in the retina the more strongly it reacts. There is no analog to digital conversion between our sensory and the brain, it is directly connected. The brain isn't executing instructions, it is more like a massively parallel collection of analog circuits that are all wired up to do whatever task they do, many of these can be monitored or controlled to various degrees with our conscious mind. We can only really focus on one thing at a time but other things can grab our focus, but there are many things that can operate with some autonomy in the background. |
