The tactile sensations mediated by the whisker-to-barrel cortex system allow rodents to efficiently detect and discriminate objects and surfaces. The temporal structure of individual whisker deflections and the temporal correlation between deflections occurring on several whiskers simultaneously vary for different tactile substrates. We studied how this distributed input is coded along the afferent pathway from the trigeminal ganglion to the cortex.
Using a piezoelectric-based 24 whisker-stimulator (Jacob et al., 2010) coupled to eletrophysiology, voltage sensitive dye imaging and 2-photon microscopy, we studied neural responses to complex multivibrissal stimulation in the rat and mouse (Jacob et al. 2008, Ego-Stengel et al., 2012, Estebanez et al., 2012, Estebanez et al., 2016).
We show that neuronal cortical networks implement several coexisting coding schemes to cope with the global and varying statistics of the tactile sensory world.
