Resumen:
Background: Rats distinguish objects differing in surface this paper we characterized some aspects of texture touch. We analyzed the multifiber discharge from a materials (wood, metal, acrylic, sandpaper) having different sandpaper (P1000) to obtain close degrees of roughness two-branch facial nerve stimulation. We also vibrissa as a way to improve the tactile information reference signal (control) – vibrissa sweeping the air Square (RMS) and the Power Spectrum Density (PSD).Results: We extracted the information about texture activity of one vibrissa innervation, using the RMSproduced the best differentiation for RMS values and pressure for texture discrimination. The frequencypressure levels and showed that the differences materials but could be related to other texture  parameters.Conclusion: Our results suggest that the physical transduced by the trigeminal sensory system of rats, changes. Likewise, varying the pressure could represent information acquisition for texture  discrimination.
