How are raw sensory signals transformed into a brain representation of the world that surrounds us? The question was first posed over 100 years ago, but new experimental strategies make the challenge more exciting than ever. SISSA investigators have now uncovered the contributions to perception of a brain region called posterior parietal cortex. In two separate papers published in Neuron and Nature, they show that posterior parietal cortex contributes to the merging of signals from different sensory modalities, as well the formation of memories about the history of recent stimuli.
