Our lives are now dependent upon the computer and what it tells you. With the exception of 7 I do think a lot of writers equate neurons with big wet transistors , I don't think I've read anything that compares brain functions with computer circuitry in any kind of a literal sense. You see, although a computer is able to solve problems at lightning speeds, it is still only limited to solve a particular kind of problem that matches the logic programmed into it. A wide variety of evidence from other domains suggests that we are only beginning to understand the importance of embodiment in information processing. Cognitive psychologists even claimed to have found this module, based on patients with damage to a region of the brain known as Broca's area. Difference 9: The brain is a self-organizing system At the processor level the stored program computer is not designed to be self-organising â so one would not expect it to be! Tool Module: Primatology Tool Module: Human Memory versus Computer Memory In some ways, human memory and computer memory are similar.
But the biggest difference between humans and computers are emotions. In contrast, although any one of your memories certainly involves the activity of specific neurons, you can retrieve it by activating just a portion of the network of neurons where it was encoded. If you can precisely model that information, then I don't know why you wouldn't be able to generate a conscious mind. Therefore, can we term the human brain equivalent to computer memory? The Computer Throughout history, people have compared the brain to different inventions. A block in human memory can not be targeted for an erase.
There, that's one difference between a human memory and computer memory. How can you help your audience move your information to long-term memory? Secondly, if I could respond to John Walters comment on flight as an analogue. Linearity and analog systems notwithstanding, I can say with the hindsight of a huge generational gap that it just seems silly to me that they didn't consider multi-layered networks. Clearly the areas of the brain are not as discrete as those in our computers, but don't we still refer to experience occurring in the neocortex? One estimate has placed it at about 3. A surprising set of has shown that even after being asked hundreds of times which simple geometrical shapes are displayed on a computer screen, human subjects continue to answer those questions by gaze rather than rote memory.
Now, I will admit that I'm not really that well-read on the subject, so maybe I've just been lucky so far. Conversely, another reason we may not detect the changes is simply that we perceive a coherently richly detailed world with everything perceived simultaneously, when in fact we do not. It may not be so much evolution, but the end results would become truly revolutionary. But the idea of Peyton Manning winning a superbowl is distasteful and unlikely, but it happened too. There are many differences between the human brain and the computer, for example, the capacity to learn new things. Difference 9: The brain is a self-organizing system This point follows naturally from the previous point - experience profoundly and directly shapes the nature of neural information processing in a way that simply does not happen in traditional microprocessors.
Maybe some research into the old tube pentodes and their marvelous integrating circuits might be in order. Computers are probably the most important innovations of our times. Other than that I'm not quite clear on what you were saying. The computer stores data sequentially, the brain do not. I guess there would be at some level at least. The problem was that what I was doing was philosophically incompatible with the âreligionâ of the Stored Program Computer and through the 1970s and 1980's I found it impossible to get a university grant, or to get many peer-reviewed papers past the deeply entrenched computer science âpriesthood. If Moore's law holds, I don't see why we can't have supercomputers within ten years that could simulate a human brain, given a model that we probably won't have for another 15 years.
Each of your points is either not true or it just lists an area where the brain is currently at a high complexity level. So yes, there are alternate computer architectures that more closely resemble a brain. If the logic can solve the problem, then you will be able to get the result in a matter of seconds. However I feel that is really saying no more than that a circuit board and a brain used different mechanisms to order to do what they do. A look at Memory Management Memory management is the responsibility and a crucial skill that every computer user must have. The distinction between the actual brain and the computer model only disappears when the model is completely accurate.
In technical terms, human memory is content-addressable, or memory based on concepts and their relationships with other concepts, as organized and stored in a person's mind. If you concede this point â and that the brains cells have different mechanisms operating in the same âboxâ - the analogy is with a computer on a single chip â which also has everything in the same box. Though it looks like human brain but there are lots of difference between computer memory and human brain. Minor point perhaps, but I think that there is a huge difference between trying to recreate the brain and tring to achieve flight. More generally, the points you have raised are very important ones - particularly your assertion that the brain is nothing like a standard desktop - maybe your idea of writing another one on the similarities is a good one on the functional nature of the two rather than the structural nature! In any case, no process can be said to actually be consciousness, any more than a digital piano can be called a musician, even if it has a massive repertoire with complex programs that make it indistinguishable from a human player. As a result, retrieval from memory always slightly alters those memories usually making them stronger, but sometimes making them less accurate - see for more on this. However, you can make your computer work faster than before by going for memory upgrade.
Because unless you were recreating the wetware, an emulation of the brain on any other architecture is going to be sub-optimal. Over 40 years ago, as a ânaive noviceâ in the computer industry I was looking at a major commercial system say 250,000 customers, 5,000 product lines, 25,000 transactions a day â and a dynamically changing market. Universal Modeling Languge, Design Patterns, etc. The military embarked on the process of building a computer that would help analyze their complex arithmetic. Difference 6 and 9: As noted, there are some special systems which allows reconfiguring hardware vs software to suit the task, and they may become more popular because they also save energy. To assume that current simulations of the spreading activation of a neuron works with a lookup table - the current method - is accurate is to assume that we know all about how this addressing works. While we might be able to install new information onto a computer it can never learn new material by itself.
Original blog illustration by Memory management is an essential skill that every programmer develops over time. A computer memory acts like the human brain. But the human brain is responsible for, thought, feelings, creativity, and other qualities that make us humans. The fact that brains and therefore from point 6, the mind are embodied have a body which is localised in the real world is, I believe, the most important constraint that is on this system. We remember each time we failed, each time someone bullied us, each time someone made fun of us, each time someone got ahead of us. It was boom time all round.
So the question is then analog versus digital. Lichtenberg Although the brain-computer metaphor has served cognitive psychology well, research in cognitive neuroscience has revealed many important differences between brains and computers. After working for telecom giant Comcast and traveling to Oregon, he's written business and technology articles for both online and print publications, including Salon. We have seen computers doing complex assignments like launching of a rocket or analysis from outer space. The brain needs nutrients like oxygen and sugar for power; the computer needs electricity to keep working.
