DESCRIPTION:Daniel Shulz\, Neural Processing\, Neuromodulation and sensory
  plasticity\, Unit of Neuroscience\, Information et Complexity\, Gif-sur-Y
 vette\, France\n \nThe tactile sensations mediated by the whisker-to-barr
 el cortex system allow rodents to efficiently detect and discriminate obje
 cts and surfaces. The temporal structure of individual whisker deflections
  and the temporal correlation between deflections occurring on several whi
 skers simultaneously vary for different tactile substrates. We studied how
  this distributed input is coded along the afferent pathway from the trige
 minal ganglion to the cortex.\nUsing a piezoelectric-based 24 whisker-stim
 ulator (Jacob et al.\, 2010) coupled to eletrophysiology\, voltage sensiti
 ve dye imaging and 2-photon microscopy\, we studied neural responses to co
 mplex multivibrissal stimulation in the rat and mouse (Jacob et al. 2008\,
  Ego-Stengel et al.\, 2012\, Estebanez et al.\, 2012\, Estebanez et al.\, 
 2016).\nWe show that neuronal cortical networks implement several coexisti
 ng coding schemes to cope with the global and varying statistics of the ta
 ctile sensory world.  \n
