Sensory signals from whiskers are typically rich in both spatial and temporal structure, and are used by many animals to guide a variety of adaptive behaviors. To explore possible neural mechanisms underlying whisker-guided behavior, we constructed Darwin IX, a mobile physical device equipped with artificial whiskers and a neural simulation based on the rat somatosensory (whisker) system. We show that neuronal units with time-lagged response properties, together with the selective modulation of neural connection strengths, provide a plausible neural mechanism for the spatiotemporal transformations of sensory input necessary for both texture discrimination and selective conditioning to textures.
