The perception of our limbs in space is built upon the integration of visual, tactile, and proprioceptive signals. Accumulating evidence suggests that these signals are combined in areas of premotor, parietal, and cerebellar cortices. However, it remains to be determined whether neuronal populations in these areas integrate hand signals according to basic temporal and spatial congruence princip...

Although visually responsive neurons predominate in the deep layers of the superior colliculus (SC), the majority of them also receive sensory inputs from nonvisual sources (i.e. auditory and/or somatosensory). Most of these 'multisensory' neurons are able to synthesize their cross-modal inputs and, as a consequence, their responses to visual stimuli can be profoundly enhanced or depressed in t...

In rodents, as in other species, regions of secondary somatosensory cortex (SII) may be distinguished from primary cortex (SI) both anatomically and electrophysiologically. However, the number of rodent SII subregions, their somatotopic organization, and their function are poorly understood. The presence of multisensory responsive neurons in some areas of SII suggests that one of its roles may ...

Neurons in the superior colliculus (SC) integrate cross-modal inputs to generate responses that are more robust than to either input alone, and are frequently greater than their sum (superadditive enhancement). Previously, the principles of a real-time multisensory transform were identified and used to accurately predict a neuron's responses to combinations of brief flashes and noise bursts. Ho...

Although the study of multisensory processes and the study of synaesthesia both represent burgeoning fields of inquiry, there has been little attempt to bridge between these two research topics. This is somewhat surprising, as these two are undoubtedly heavily interrelated from both a psychological and neuroscience perspective. The goal of the present issue is explore these interrelationships, ...

The current research aimed at improving EFL Fifth grade dyslexic pupils' reading skills (Phonemic Awareness –Reading Accuracy- Spelling -Reading Comprehension) through using a VAKT based Program. Forty pupils enrolled in the fifth year, Primary stage, Menoufia governorate, Egypt were participants of this research. Data collection was on sequential mixed methods approach. qualitative phase is re...

When we are constantly and simultaneously bombarded with various types of sensory inputs, how do we make decisions or motor outputs to deal with the world in a meaningful manner? This is a central issue in multisensory integration. One example of such type of processing is eating, as placing food in one's mouth provides taste, olfactory and somatosensory (texture, temperature) information (Verh...

Interactions between different sensory modalities can be observed in unimodal areas of the cortex, as revealed by recent neuroimaging studies. A new report by Macaluso and colleagues ( [this issue of Neuron]) shows that crossmodal effects of tactile stimulation in visual cortex critically depend on the spatial congruence of multisensory inputs. This work is discussed in relation to neural and c...

Multisensory integration is central to perception, and recent work drafts it as a distributed process involving many and even primary sensory cortices. Studies in behaving animals performing a multisensory task provide an ideal means to elucidate the underlying neural basis, and a new study by Lemus et al. in this issue of Neuron thrusts in this direction.
