Micro- and mesoscopic aspects of cortical neurodynamics

Abstract:
The terms "microscopic" and "mesoscopic" are borrowed from physics and used here to denote two levels of describing functional organization of neocortical neuronal activity, basically (multiple) single unit firing behavior and local field potential activity, respectively. These terms appear suitable because the (yet unsolved) problem of combining these two levels of description bears similarities to the corresponding problem in physics. In the talk I will try to present a few examples where microscopic or macroscopic neuronal observables have been demonstrated to be relevant for rodent behavioral neuroscience. One of these examples will be the robust phenomenon of stimulus-specific adaptation for which microscopic and mesoscopic observables have yielded discernible but potentially interrelatable accounts.
