Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving and of Spatial Vision.

Visual objects presented around the time of saccadic eye movements are strongly mislocalized towards the saccadic target, a phenomenon known as "saccadic compression." Here we show that perisaccadic compression is modulated by the presence of a visual saccadic target. When subjects saccaded to the center of the screen with no visible target, perisaccadic localization was more veridical than when tested with a target. Presenting a saccadic target sometime before saccade initiation was sufficient to induce mislocalization. When we systematically varied the onset of the saccade target, we found that it had to be presented around 100 ms before saccade execution to cause strong mislocalization: saccadic targets presented after this time caused progressively less mislocalization. When subjects made a saccade to screen center with a reference object placed at various positions, mislocalization was focused towards the position of the reference object. The results suggest that saccadic compression is a signature of a mechanism attempting to match objects seen before the saccade with those seen after.

New Research in Behaioural Brain Research

Congratulations to Eckart, Concetta and David, whose latest paper has just been accepted for publication in Behavioural Brain Research!

To interact rapidly and effectively with our environment, our brain needs access to a neural represen-tation of the spatial layout of the external world. However, the construction of such a map poses majorchallenges, as the images on our retinae depend on where the eyes are looking, and shift each time wemove our eyes, head and body to explore the world. Research from many laboratories including ourown suggests that the visual system does compute spatial maps that are anchored to real-world coordi-nates. However, the construction of these maps takes time (up to 500 ms) and also attentional resources.We discuss research investigating how retinotopic reference frames are transformed into spatiotopicreference-frames, and how this transformation takes time to complete. These results have implicationsfor theories about visual space coordinates and particularly for the current debate about the existence ofspatiotopic representations.

New Research in Journal of Neuroscience

Congratulations to Alice, Monica e Concetta for their research just published in JN

The research shows that time intervals are compressed around the time of hand movement to produce distortions of perceived time similar to those reposted for visual motion. Taken together these results suggest common strategies within different sensorimotor systems to achieve perceptual stability

New Research in PNAS

Congratulations to Marco, Giovanni and Dave for their research just published in PNAS

The research shows that people are consistently drawn towards the past trials when making numerical judgements. Their analysis shows that such behaviour leads to a logarithmic pattern response which previously has been associated to the shape of the internal representation of magnitiude

Congratulation to Claudia Lunghi who has won the prize for the best thesis in biomedical research in Florence University for 2013! The competition was very tought as it concerned all biomedical departments in Florence University, nevertheless Claudia obtained an outstanding victory with her study on binocular rivarly and brain plasticity.  Well done Claudia, you are a champion!

Auditory and tactile signals combine to influence vision during binocular rivalry

Claudia LunghiMaria Concetta Morrone and David Alais

Resolution of perceptual ambiguity is one function of cross-modal interactions. Here we investigate whether auditory and tactile stimuli can influence binocular rivalry generated by interocular temporal conflict in human subjects. Using dichoptic visual stimuli modulating at different temporal frequencies, we added modulating sounds or vibrations congruent with one or the other visual temporal frequency. Auditory and tactile stimulation both interacted with binocular rivalry by promoting dominance of the congruent visual stimulus. This effect depended on the cross-modal modulation strength and was absent when modulation depth declined to 33%. However, when auditory and tactile stimuli that were too weak on their own to bias binocular rivalry were combined, their influence over vision was very strong, suggesting the auditory and tactile temporal signals combined to influence vision. Similarly, interleaving discrete pulses of auditory and tactile stimuli also promoted dominance of the visual stimulus congruent with the supra-modal frequency. When auditory and tactile stimuli were presented at maximum strength, but in anti-phase, they had no influence over vision for low temporal frequencies – a null effect again suggesting audio-tactile combination. We also found that the cross-modal interaction was frequency-sensitive at low temporal frequencies, when information about temporal phase alignment can be perceptually tracked. These results show that auditory and tactile temporal processing is functionally linked, suggesting a common neural substrate for the two sensory modalities, and that at low temporal frequencies visual activity can be synchronized by a congruent cross-modal signal in a frequency-selective way, suggesting the existence of a supra-modal temporal binding mechanism.
