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.

The center-surround receptive field structure, ubiquitous in the visual system, is hypothesized to be evolutionarily advantageous in image processing tasks. We address the potential functional benefit...
Prior research has shown contextual manipulations involving temporal and sequence related factors significantly moderate attention-related responses, as indexed by the P3b event-related-potential, tow...
Cortical plasticity in congenitally blind individuals leads to cross-modal activation of the visual cortex and may lead to superior perceptual processing in the intact sensory domains. Although mental...
When people make decisions about sequentially presented items in psychophysical experiments, their decisions are always biased by their preceding decisions and the preceding items, either by assimilat...
When taught a label for an object and then asked whether an exemplar of that object or a novel object is the referent of a novel label, children favor the novel object. Preschool-aged children tend no...
This study will investigate the effect of enhanced visual and cross-modal environments upon the visual attentiveness of multiply handicapped children diagnosed with Cerebral Palsy (CP) and...
The protocol involves functional Magnetic Resonance Imaging and Magnetic Resonance Spectroscopy acquisitions immediately before and after Low Field Magnetic Stimulation treatment on two se...
Occipital stroke is associated with homonymous visual field defects (occurring on one side of the visual field). Despite spontaneous recovery, some degree of defect is often permanent. Cur...
Nonstandard time-schedules work are widespread in the world of work. Shift and night work have been shown to be responsible for a desynchronization of biological rhythms, associated with m...
This study is designed to see if doing regular training on a spatial imagery task leads to improvements in the ability to do the trained spatial imagery task and in the ability to get arou...
Loss of sensitivity to sounds as a result of auditory stimulation, manifesting as a temporary shift in auditory threshold. The temporary threshold shift, TTS, is expressed in decibels.
Job schedule in which working hours deviate from the standard hours (e.g., evening shift, night shift or rotating shift).
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
Integration of spatial information perceived by visual and/or auditory CUES.
A process through which individuals encode information about their environmental CUES to facilitate SPATIAL NAVIGATION.
