Relative Unisensory Strength and Timing Predict Their Multisensory Product

Relative unisensory strength and timing predict their multisensory product.

Understanding the principles by which the brain combines information from different senses provides us with insight into the computational strategies used to maximize their utility. Prior studies of the superior colliculus (SC) neuron as a model suggest that the relative timing with which sensory cues appear is an important factor in this context. Cross-modal cues that are near-simultaneous are...

Evoked Multisensory Cortical Representations During Unisensory Stimulation

The differing impact of multisensory and unisensory integration on behavior.

Pooling and synthesizing signals across different senses often enhances responses to the event from which they are derived. Here, we examine whether multisensory response enhancements are attributable to a redundant target effect (two stimuli rather than one) or if there is some special quality inherent in the combination of cues from different senses. To test these possibilities, the performan...

Title: Alterations to multisensory and unisensory integration by stimulus competition

words: 192) 35 36 In environments containing sensory events at competing locations, selecting a target for orienting 37 requires prioritization of stimulus values. Although the superior colliculus (SC) is causally 38 linked to the stimulus selection process, the manner in which SC multisensory integration 39 operates in a competitive stimulus environment is unknown. Here we examined how the act...

Unisensory and Multisensory Disruptions in Autism Spectrum Disorders

SENSORY OBSERVATIONS IN AUTISM One insight into the sensory disturbances in autism comes from autobiographical reports. For example Temple Grandin, a well known highfunctioning professor with autism, describes her hearing experiences as “like having a sound amplifier set on maximum loudness.” Other reports indicate difficulty for individuals with ASD to process stimuli from multiple senses conc...
