Stimulus-induced gamma activity in the electrocorticogram of freely moving telemetric implanted rats: the neuronal signature of novelty detection. Dissertation Zur Erlangung des Grades Doktor der Naturwissenschaften Am Fachbereich Biologie Der Johannes Gutenberg-Universität Mainz vorgelegt von Damien Lapray geb. am 03.05.1979 in Migennes, Frankreich Mainz, 2009 Tag der mündlichen Prüfung: 20.09.2009 A mon Père, Ma Mère, Maty, Benoît, Et Olivier. « Brains are characterized by every property that engineers and computer scientists detest and avoid. They are chaotic, unstable, nonlinear, nonstationary, non-Gaussian, asynchronous, noisy, and unpredictable in fine grain, yet undeniably they are among the most successful devices that a billion years of evolution has produced. » Walter J.
