Apologies for multiple postings. Dear Colleagues, The following book is now available: "Elements of Neurogeometry. Functional architectures of vision" (Springer). This book describes several mathematical models of the primary visual cortex, referring them to a vast ensemble of experimental data and putting forward an original geometrical model for its functional architectures Using concepts as wavelet analysis; contact, symplectic, and sub-Riemannian geometry, it provides a systematic interpretation of a number of important neurophysiological observations in a welldefined mathematical framework. More information (in particular the Table of contents) can be found on the following web pages: <http://www.springer.com/fr/book/9783319655895>http://www.springer.com/fr/book/9783319655895 <http://jeanpetitot.com/Petitot_Springer/9783319655895-t1(contents).pdf>http://jeanpetitot.com/Petitot_Springer/9783319655895-t1(contents).pdf With my best regards, Jean Petitot
