Haptic sensing of objects acquires information about a number of properties. This review summarizes current understanding about how these properties are processed in the cerebral cortex of macaques and humans. Nonnoxious somatosensory inputs, after initial processing in primary somatosensory cortex, are partially segregated into different pathways. A ventrally directed pathway carries information about surface texture into parietal opercular cortex and thence to medial occipital cortex. A… 
Neural representations of haptic object size in the human brain revealed by multivoxel fMRI patterns.
It is suggested that regions of the intraparietal sulcus and the lateral prefrontal cortex compute representations of haptic size that abstract over the specific peripheral afferent signals generated in a grasp, indicating that these representations may be partly modality-general.
Visuo-haptic object perception
Neural Evidence of Hierarchical Cognitive Control during Haptic Processing: An fMRI Study
The results point for the first time to a hierarchical organization in the neural substrates underlying haptic monitoring during manipulation with the SMG as a higher-order hub comparing actual and predicted somatosensory input, and SI as a lower-order site involved in the detection of more specialized haptic mismatch.
Gaze direction influences grasping actions towards unseen, haptically explored, objects
It is hypothesized that if the motor system uses HOIs stored in a retinotopic coding in the visual cortex, then its use is likely to depend at least in part on eye position, indicating sharing of resources between the haptic and the visual/oculomotor system to delayed haptic grasping.
Electrocorticography Evidence of Tactile Responses in Visual Cortices
Assessing tactile responses in both low-level and extrastriate visual cortices using electrocorticography recordings in a human participant adds to a mounting literature in support of task-sensitive and sensory-independent mechanisms underlying functions like spatial, motion, and self-processing in the brain and extending from higher-level as well as to low- level cortices.
Brain networks underlying conscious tactile perception of textures as revealed using the velvet hand illusion
The present results indicate that S1 is associated with the conscious tactile perception of textures, which may be achieved via interactions with higher order somatosensory areas.


Dual pathways for haptic and visual perception of spatial and texture information
Multisensory cortical processing of object shape and its relation to mental imagery
Ratings of the vividness of visual imagery strongly predicted the amount of haptic shape-selective activity in the right, but not in the left, lateral occipital complex, and visual imagery appears to contribute to activation of some,but not all, visual cortical areas during haptic perception.
Preserved Haptic Shape Processing after Bilateral LOC Lesions
It is demonstrated that LOC is not necessary for recognizing objects via touch, despite being severely impaired in visual shape recognition, in a patient with extensive lesions involving LOC bilaterally.
Selective visuo‐haptic processing of shape and texture
A human functional magnetic resonance imaging study in which shape and texture perception were contrasted using haptic stimuli presented to the right hand, and visual stimuli presented centrally corroborates and elaborates previous suggestions of specialized visuo‐haptic processing of texture and shape.
Convergence of visual and tactile shape processing in the human lateral occipital complex.
It is suggested that LOtv, the cortical region LOtv for the lateral occipital tactile-visual region, is involved in recovering the geometrical shape of objects.
Visuo-haptic object-related activation in the ventral visual pathway
Using fMRI to map object-related brain regions, it is suggested that neuronal populations in the occipito–temporal cortex may constitute a multimodal object- related network.
Neural networks active during tactile form perception: common and differential activity during macrospatial and microspatial tasks.
Combined activation and deactivation of visual cortex during tactile sensory processing.
Functional magnetic resonance imaging results suggest that tactile processing affects occipital cortex via two distinct pathways: a suppressive top-down pathway descending through the visual cortical hierarchy and an excitatory pathway arising from outside the visual cortex hierarchy that drives area V1 directly.
