“…There has been some debate related to the dependence of haptic processing on visual processing, particularly visual imagery [2,8,16,36,40,46]. The current study found that the geometric conditions elicited greater involvement of the intraparietal sulcus (IPS), a region associated with higher level visuo-spatial processing, particularly with respect to visual imagery.…”

Two experiments are reported that used fMRI to compare the brain activation during the imagery of material and geometric object features. In the first experiment, participants were to mentally evaluate objects along either a material dimension (roughness, hardness and temperature; e.g., Which is harder, a potato or a mushroom?) or a geometric dimension (size and shape; e.g., Which is larger, a pumpkin or a cucumber?). In the second experiment, when given the name of an object and either a material (roughness and hardness) or geometric (size and shape) property participants rated the object on a scale from 1 to 4. Both experiments were designed to examine the underlying neural substrate that supports the processing of material object properties with respect to geometric properties. Considering the relative amount of activation across the two types of object properties, we found that (1) the interrogation of geometric features differentially evokes visual imagery which involves the region in and around the intraparietal sulcus, (2) the interrogation of material features differentially evokes the processing of semantic object representations which involves the inferior extrastriate region, and (3) the lateral occipital cortex (LOC) responds to shape processing regardless of whether the feature being queried is a material or geometric feature.

“…Additionally, Sathian et al have shown an important role for visual cortex, particularly the occipital/parietal portion, in tactile discrimination [25,36,40,46]. For example, disruption of occipital function with transcranial magnetic stimulation (TMS) was found to interfere with tactile discrimination of grating orientation [25].…”

“…Consistent with this suggestion, studies have demonstrated that the visual cortex of blind individuals is activated during tasks such as Braille reading (Cohen et al, 1997;Sadato et al, 1996) and haptic object recognition (Amedi, Raz, Azulay, Malach, & Zohary, 2010). Moreover, the existence of networks between vision and touch in normally sighted individuals is supported by neuroimaging studies; visual areas have been shown to be activated during tactile orientation discrimination (Sathian & Zangaladze, 2002;Sathian, Zangaladze, Epstein, & Grafton, 1999), haptic object recognition (Amedi, Jacobson, Hendler, Malach, & Zohary, 2002;Amedi et al, 2010;Deibert, Kraut, Kremen, & Hart, 1999;James, Humphrey, Gati, Servos, Menon, & Goodale, 2002;Pietrini et al, 2004), and Braille reading in sighted subjects following 5 days of complete visual deprivation (Merabet et al, 2008). Furthermore, there is behavioral evidence for the influence of tactile inputs on visual perception.…”

Recently, Guzman-Martinez, Ortega, Grabowecky, Mossbridge, and Suzuki (Current Biology : CB, 22(5), [383][384][385][386][387][388] 2012) reported that observers could systematically match auditory amplitude modulations and tactile amplitude modulations to visual spatial frequencies, proposing that these cross-modal matches produced automatic attentional effects. Using a series of visual search tasks, we investigated whether informative auditory, tactile, or bimodal cues can guide attention toward a visual Gabor of matched spatial frequency (among others with different spatial frequencies). These cues improved visual search for some but not all frequencies. Auditory cues improved search only for the lowest and highest spatial frequencies, whereas tactile cues were more effective and frequency specific, although less effective than visual cues. Importantly, although tactile cues could produce efficient search when informative, they had no effect when uninformative. This suggests that cross-modal frequency matching occurs at a cognitive rather than sensory level and, therefore, influences visual search through voluntary, goaldirected behavior, rather than automatic attentional capture.

“…There is also evidence that such facilitative relations between visual and somatosensation are reciprocal. Findings by Sathian and colleagues indicate clear activations of visual cortices by unimodal tactile stimuli (Sathian et al, 1997;Sathian and Zangaladze, 2002;Peltier et al, 2007). Similarly, another recent study found increased SI activation following visuo-tactile stimulation compared with touch alone (Dionne et al, 2010).…”

The visual context of seeing the body can reduce the experience of acute pain, producing a multisensory analgesia. Here we investigated the neural correlates of this "visually induced analgesia" using fMRI. We induced acute pain with an infrared laser while human participants looked either at their stimulated right hand or at another object. Behavioral results confirmed the expected analgesic effect of seeing the body, while fMRI results revealed an associated reduction of laser-induced activity in ipsilateral primary somatosensory cortex (SI) and contralateral operculoinsular cortex during the visual context of seeing the body. We further identified two known cortical networks activated by sensory stimulation: (1) a set of brain areas consistently activated by painful stimuli (the so-called "pain matrix"), and (2) an extensive set of posterior brain areas activated by the visual perception of the body ("visual body network"). Connectivity analyses via psychophysiological interactions revealed that the visual context of seeing the body increased effective connectivity (i.e., functional coupling) between posterior parietal nodes of the visual body network and the purported pain matrix. Increased connectivity with these posterior parietal nodes was seen for several pain-related regions, including somatosensory area SII, anterior and posterior insula, and anterior cingulate cortex. These findings suggest that visually induced analgesia does not involve an overall reduction of the cortical response elicited by laser stimulation, but is consequent to the interplay between the brain's pain network and a posterior network for body perception, resulting in modulation of the experience of pain.
