Many neurons in the superior colliculus (SC) integrate sensory information from multiple modalities, giving rise to significant response enhancements. Although enhanced multisensory responses have been shown to depend on the spatial and temporal relationships of the stimuli as well as on their relative effectiveness, these factors alone do not appear sufficient to account for the substantial he...

We propose a Bayesian nonparametric model of multisensory perception based upon the Indian buffet process. The model includes a set of latent variables that learn multisensory features from unisensory data. The model is highly flexible because it makes few statistical assumptions. In particular, the number of latent multisensory features is not fixed a priori. Instead, this number is estimated ...

Multisensory research is often interpreted according to three rules: the spatial rule, the temporal rule, and the law of inverse effectiveness. The spatial and temporal rules state that multisensory stimuli are integrated when their environmental sources occur at similar locations and times, respectively. The law of inverse effectiveness states that multisensory stimuli are integrated inversely...

Although sensory perception and neurobiology are traditionally investigated one modality at a time, real world behaviour and perception are driven by the integration of information from multiple sensory sources. Mounting evidence suggests that the neural underpinnings of multisensory integration extend into early sensory processing. This article examines the notion that neocortical operations a...

Surrounded by multiple objects and events, receiving multisensory stimulation, our brain must sort through relevant and irrelevant multimodal signals to correctly decode and represent the information from the same and different objects and, respectively, events in the physical world. Over the last two decades, scientific interest has increased dramatically in how we integrate multisensory infor...

Normal sensory experience is necessary for the development of multisensory processing, such that disruption through environmental manipulations eliminates or alters multisensory integration. In this Neuro Forum, we examine the recent paper by Xu et al. (J Neurosci 32: 2287-2298, 2012) which proposes that the statistics of cross-modal stimuli encountered early in life might be a driving factor f...

How do people learn multisensory, or amodal, representations, and what consequences do these representations have for perceptual performance? We address this question by performing a rational analysis of the problem of learning multisensory representations. This analysis makes use of a Bayesian nonparametric model that acquires latent multisensory features that optimally explain the unisensory ...

It has recently been demonstrated that the maturation of normal multisensory circuits in the cortex of the cat takes place over an extended period of postnatal life. Such a finding suggests that the sensory experiences received during this time may play an important role in this developmental process. To test the necessity of sensory experience for normal cortical multisensory development, cats...

When I am looking at my coffee machine that makes funny noises, this is an instance of multisensory perception - I perceive this event by means of both vision and audition. But very often we only receive sensory stimulation from a multisensory event by means of one sense modality, for example, when I hear the noisy coffee machine in the next room, that is, without seeing it. The aim of this pap...

Multisensory integration and crossmodal attention have a large impact on how we perceive the world. Therefore, it is important to know under what circumstances these processes take place and how they affect our performance. So far, no consensus has been reached on whether multisensory integration and crossmodal attention operate independently and whether they represent truly automatic processes...
