In search of the origin of the crime!
Brain Research is an exciting field – there is mystery to it: Is there the “fingerprint” of a crime in the brain? Neuroscientists this issue go to the bottom and look in the brain, according to the location of the crime.
In laboratories and courtrooms that opens to a revolution. The reason for this is the criminal brain research, with the latest technology and research the origin of the crime under investigation. Whether it is terrorists or wanted to neuropsychological court’s opinion on criminals – the social relevance of this brain research is high.
And the ethical issues arising from it, are serious: Can the new research for the prevention of crime to use? Should we do this? How and to what extent?
With many fascinating case studies, this fascinating book on the current state of research.
The brain works statistically
The man uses all his senses to perceive objects. All of these sense impressions the brain to integrate our complex perceptions. Which of the meaning of this crucial data, depends on whether we are the object visually, haptic, or otherwise wish to. Depending on the question we weigh these impressions. Researchers have now discovered that the brain is achieved by statistical aspects.
Marc Ernst vom Tübinger ‘Max-Planck-Institute for Biological Cybernetics and Martin Banks from the’ University of California ‘Berkeley describe in the current issue of’ Nature ‘, as our brains in the transfer of visual and tactile sensations after statistically scales approach.
‘Noisy’ signals
Just as physical measuring devices always have a small error tolerance, are also our sense organs are not perfect: All the brain reported impressions are on their way, more or less “noisy” (blurred).
In exercising the brain, however, should use all available information sources as the best use. The fact that our hands e.g. also known as “visual aids” may serve to manually scan the visual perception that is specifically and strongly influenced, neuroscientists had already in earlier experiments found.
Statistics provides optimal signal combination
The noisy (disturbed) and the uncertain meaning, for example data the keys are, the less weight should be in competition with other sources of information (such as vision) get.
Mathematics would be considered a statistical model, the so-called maximum likelihood estimation method, the optimal combination of supply, which varies reliable signals are offset so that the total noise is minimized. Only in this way, all available meaning information about an object as useful as possible, exploited.
