  • In the visual system of primates, different neuronal pathways are specialized for processing information about the spatial coordinates of objects and their identity — that is, 'where' and 'what'. By contrast, rats and other nocturnal animals build up a neuronal representation of 'where' and 'what' by seeking out and palpating objects with their whiskers. We present recent evidence about how the brain constructs a representation of the surrounding world through whisker-mediated sense of touch… CONTINUE READING
