Summary of "Spatial receptive field shift by preceding cross-modal stimulation in the cat superior colliculus."

It has been known for some time that sensory information of one type can bias the spatial perception of another modality. However, there is a lack of evidence of this occurring in individual neurons. In this study, we found that the spatial receptive field (RF) of superior colliculus (SC) multisensory neurons could be dynamically shifted by a preceding stimulus in a different modality. The extent to which the RF shifted was dependent on both temporal and spatial gaps between preceding and following stimuli as well as the salience of the preceding stimulus. This result provides a neural mechanism that could underlie the process of cross-modal spatial calibration.
