Experimental findings reveal how sensory signals combine in the posterior parietal cortex, indicating their role in spatial awareness and navigation.

This study aims to uncover the neural mechanisms underlying multimodal integration for spatial representation in the posterior parietal cortex.
Conducted experiments in the posterior parietal cortex, specifically in areas LIP, 7a, and MSTd.
Investigated the combination of visual, somatosensory, auditory, and vestibular signals for spatial processing.
Utilized a gain-field mechanism to analyze spatial representation.
Area LIP and 7a effectively represent the location of stimuli in relation to the observer and environment.
Area MSTd integrates visual motion with eye-movement and vestibular signals, aiding in navigation.
All three cortical areas utilize multimodal integration to create common spatial representations.

Richard A. Andersen (1997) studied this question.
