“…For instance, middle temporal area (area MT), which is well studied given its prominent role in visual motion processing, also activates in response to tactile motion [50][51][52]. rTMS targeting area MT impairs tactile motion speed judgements [53]. Collectively, these NIBS studies support the emerging view that brain regions which have been traditionally ascribed visual functions may also contribute to non-visual perception.…”

One contribution of 15 to a theme issue 'Controlling brain activity to alter perception, behaviour and society'. We rely on rich and complex sensory information to perceive and understand our environment. Our multisensory experience of the world depends on the brain's remarkable ability to combine signals across sensory systems. Behavioural, neurophysiological and neuroimaging experiments have established principles of multisensory integration and candidate neural mechanisms. Here we review how targeted manipulation of neural activity using invasive and non-invasive neuromodulation techniques have advanced our understanding of multisensory processing. Neuromodulation studies have provided detailed characterizations of brain networks causally involved in multisensory integration. Despite substantial progress, important questions regarding multisensory networks remain unanswered. Critically, experimental approaches will need to be combined with theory in order to understand how distributed activity across multisensory networks collectively supports perception.

“…A required sample size of 18 participants was estimated using G*Power 3.148, based on a desired power of 0.95 and the average effect size of impaired tactile motion processing caused by TMS over V5/hMT+ in previous studies (η 2 = 0.53)1820. Eighteen healthy volunteers (right-handed; 9 females; 18–43 years old) participated for payment.…”

Human imaging studies have reported activations associated with tactile motion perception in visual motion area V5/hMT+, primary somatosensory cortex (SI) and posterior parietal cortex (PPC; Brodmann areas 7/40). However, such studies cannot establish whether these areas are causally involved in tactile motion perception. We delivered double-pulse transcranial magnetic stimulation (TMS) while moving a single tactile point across the fingertip, and used signal detection theory to quantify perceptual sensitivity to motion direction. TMS over both SI and V5/hMT+, but not the PPC site, significantly reduced tactile direction discrimination. Our results show that V5/hMT+ plays a causal role in tactile direction processing, and strengthen the case for V5/hMT+ serving multimodal motion perception. Further, our findings are consistent with a serial model of cortical tactile processing, in which higher-order perceptual processing depends upon information received from SI. By contrast, our results do not provide clear evidence that the PPC site we targeted (Brodmann areas 7/40) contributes to tactile direction perception.

“…A similar functional organization based on stimulus attributes has previously been described in several other brain regions: e.g. the lateral occipital complex for object shape processing (Amedi et al ., , ), the human middle temporal gyrus (hMT) for motion processing (Poirier et al ., ; Matteau et al ., ; Basso et al ., ), parts of the dorsal and the ventral visual streams for the processing of spatial vs. nonspatial attributes (Renier et al ., ). Here, we showed a new example of convergence of the same functional attributes into one centralized representation in the brain, which seems to be a general principle of brain organization.…”

Hearing, feeling or seeing a beat recruits a supramodal network in the auditory dorsal stream

Hearing a beat recruits a wide neural network that involves the auditory cortex and motor planning regions. Perceiving a beat can potentially be achieved via vision or even touch, but it is currently not clear whether a common neural network underlies beat processing. Here, we used functional magnetic resonance imaging (fMRI) to test to what extent the neural network involved in beat processing is supramodal, that is, is the same in the different sensory modalities. Brain activity changes in 27 healthy volunteers were monitored while they were attending to the same rhythmic sequences (with and without a beat) in audition, vision and the vibrotactile modality. We found a common neural network for beat detection in the three modalities that involved parts of the auditory dorsal pathway. Within this network, only the putamen and the supplementary motor area (SMA) showed specificity to the beat, while the brain activity in the putamen covariated with the beat detection speed. These results highlighted the implication of the auditory dorsal stream in beat detection, confirmed the important role played by the putamen in beat detection and indicated that the neural network for beat detection is mostly supramodal. This constitutes a new example of convergence of the same functional attributes into one centralized representation in the brain.
