Multisensory integration shortens physiological response latencies.
Individual superior colliculus (SC) neurons integrate information from multiple sensory sources to enhance their physiological response. The response of an SC neuron to a cross-modal stimulus combination can not only exceed the best component unisensory response but can also exceed their arithmetic sum (i.e., superadditivity). The present experiments were designed to investigate the temporal pr...
متن کاملImpact of response duration on multisensory integration.
Multisensory neurons in the superior colliculus (SC) have been shown to have large receptive fields that are heterogeneous in nature. These neurons have the capacity to integrate their different sensory inputs, a process that has been shown to depend on the physical characteristics of the stimuli that are combined (i.e., spatial and temporal relationship and relative effectiveness). Recent work...
متن کاملMultisensory Integration Produces an Initial Response Enhancement
The brain has evolved the ability to integrate information across the senses in order to improve the detection and disambiguation of biologically significant events. This multisensory synthesis of information leads to faster (and more accurate) behavioral responses, yet the underlying neural mechanisms by which these responses are speeded are as yet unclear. The aim of these experiments was to ...
متن کاملNeural correlates of multisensory reliability and perceptual weights emerge at early latencies during audio‐visual integration
To make accurate perceptual estimates, observers must take the reliability of sensory information into account. Despite many behavioural studies showing that subjects weight individual sensory cues in proportion to their reliabilities, it is still unclear when during a trial neuronal responses are modulated by the reliability of sensory information or when they reflect the perceptual weights at...
