Recent discoveries have made it possible to control computer games by thought alone, or work out what kind of item someone is thinking about from their brain signals. And that's not all. Researchers were able to use brain scans to reconstruct what someone was looking at.
In these experiments the scientists were literally able to see what people were thinking. A worrying thought, perhaps. But how did they do it? </div>

<p>The world is upside down. Or at least, the version that our eyes send to our brain is. The clever trick that happens afterwards, putting everything back the right way up, is one of the first bits of neuroscience that most children learn. But the truly astonishing part — converting the blizzard of neural signals into a mental image of familiar objects — has puzzled researchers for years. </p><p><a href="http://plus.maths.org/content/mapping-minds-eye" target="_blank">read more</a></p>http://plus.maths.org/content/mapping-minds-eye#commentsImage analysislinear algebramedicine and healthWed, 07 Mar 2012 10:46:22 +0000mf3445661 at http://plus.maths.org/contentRestoring profanity

In 1979 decorating work in a house in Vienna revealed a set of medieval frescoes depicting a cycle of songs by a 13th century poet, who was particularly fond of satirising the erotic relationships between knights and peasant maidens. The frescoes are of great historical significance, but they are badly damaged. In this article <b>Carola Schönlieb</b> explores how mathematicians use the heat
equation to fill in the gaps. </div>

<p>In the late 14th century Michel Menschein, a wealthy Viennese cloth merchant, commissioned local artists to paint a series of frescoes on the walls of his banqueting hall. The paintings depicted a cycle of songs by <a href="http://en.wikipedia.org/wiki/Neidhart_von_Reuental">Neidhart von Reuental</a>, a 13th century <i>minnesinger</i>, who was particularly fond of satirising the erotic

Not so long ago, if you had a medical complaint, doctors had to open you up to see what it was. These days they have a range of sophisticated imaging techniques at their disposal, saving you the risk and pain of an operation. <b>Chris Budd and Cathryn Mitchell</b> look at the maths that isn't only responsible for these medical techniques, but also for much of the digital revolution. </div>

<p>Images are everywhere, and electronic images in particular are playing an increasingly important role in everyday life. Doctors in hospitals use X-ray pictures to check for broken bones. Meteorologists employ images from satellites to help forecast the weather. Law enforcement officers study aerial photographs to find out where drug crops are being grown.</p><p><a href="http://plus.maths.org/content/image-analysis-modern-application-mathematics" target="_blank">read more</a></p>http://plus.maths.org/content/image-analysis-modern-application-mathematics#comments4bayes theoremImage analysismathematical modellingThu, 01 Jan 1998 00:00:00 +0000plusadmin2143 at http://plus.maths.org/content
