“…Panel C shows group average data from Ricciardi et al (2007) in a study in which subjects passively experienced Braille-like tactile flow patterns on the finger. Panel D shows group average data of van Kemenade et al (2014). In this study subjects had to identify the direction of motion of Braille-like tactile stimulation to the fingertip.…”

“…One possible reason for this wide range of findings is that a continuum of methods to define hMT+ have been used in the literature: stereotactic co-ordinates (Matteau et al 2010; Wacker et al 2011), group averaged response to visual motion localizers (Ricciardi et al 2007; Summers et al 2009), and finally using individual responses to visual motion to define hMT+ for each subject (Hagen et al 2002; Blake et al 2004; Beauchamp et al 2007; van Kemenade et al 2014). The choice of method used to define hMT+ is critical because although it has a relatively consistent position in relation to the sulcal patterns, its stereotaxic location is highly variable (Dumoulin et al 2000).…”

“…Although human motion-sensitive middle temporal cortex (hMT+ complex) is traditionally thought of as visual cortex, in recent years the human neuroimaging literature has presented several studies suggesting tactile responses (Hagen et al 2002; Blake et al 2004; Beauchamp et al 2007; Ricciardi et al 2007; Summers et al 2009; Matteau et al 2010; Sani et al 2010) selective for the direction of tactile motion (van Kemenade et al 2014) in hMT+ within sighted subjects, as well as disruption of tactile processing with rTMS inhibition over the expected site of hMT+ (Ricciardi et al 2011), even for passive tactile stimulation. This has led to the suggestion that regions within hMT+ may be supramodal, processing motion regardless of the sensory modality in which it is presented (Pascual-Leone and Hamilton 2001; Ricciardi et al 2014).…”

Re-examining overlap between tactile and visual motion responses within hMT + and STS

Here we examine overlap between tactile and visual motion BOLD responses within the human MT+ complex. Although several studies have reported tactile responses overlapping with hMT+, many used group average analyses, leaving it unclear whether these responses were restricted to sub-regions of hMT+. Moreover, previous studies either employed a tactile task or passive stimulation, leaving it unclear whether or not tactile responses in hMT+ are simply the consequence of visual imagery. Here we carried out a replication of one of the classic papers finding tactile responses in hMT+ (Hagen et al. 2002). We mapped MT and MST in individual subjects using visual field localizers. We then examined responses to tactile motion on the arm, either presented passively or in the presence of a visual task performed at fixation designed to minimize visualization of the concurrent tactile stimulation. To our surprise, without a visual task, we found only weak tactile motion responses in MT (6% of voxels showing tactile responses) and MST (2% of voxels). With an unrelated visual task designed to withdraw attention from the tactile modality, responses in MST reduced to almost nothing (<1% regions). Consistent with previous results, we did observe tactile responses in STS regions superior and anterior to hMT+. Despite the lack of individual overlap, group averaged responses produced strong spurious overlap between tactile and visual motion responses within hMT+ that resembled those observed in previous studies. The weak nature of tactile responses in hMT+ (and their abolition by withdrawal of attention) suggests that hMT+ may not serve as a supramodal motion processing module.

“…2). Even though the investigation of MT was beyond the scope of this study, some previous findings point towards an involvement of MT/V5 in motion processing across modalities (Alink et al, 2008;Blake et al, 2004;Hagen et al, 2002;Scheef et al, 2009;van Kemenade et al, 2014;Wacker et al, 2011). Therefore, it is possible that our experimental manipulation might also has affected oscillatory activity in MT.…”

“…Crucially, dorsal pathway visual areas also appear to support processing for non-preferred modalities. 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].…”

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.
