Analogous intermediate shape coding in vision and touch.
نویسندگان
چکیده
We recognize, understand, and interact with objects through both vision and touch. Conceivably, these two sensory systems encode object shape in similar ways, which could facilitate cross-modal communication. To test this idea, we studied single neurons in macaque monkey intermediate visual (area V4) and somatosensory (area SII) cortex, using matched shape stimuli. We found similar patterns of shape sensitivity characterized by tuning for curvature direction. These parallel tuning patterns imply analogous shape coding mechanisms in intermediate visual and somatosensory cortex.

How Human can Discriminate between Convex and Concave Shape from the Tactile Stimulus
Computational model of how vision system reconstructs the world information from visual stimulus has been studied so far (Marr 1982). Many of the famous achievements done by David Marr have been applied to the computer vision studies in the engineering field. On the other hand, little is known about how people can reconstruct 3D information from 2D stimulus distribution in the sense of touch. I...
متن کاملHaptics disambiguates vision in the perception of pictorial relief
In this study we demonstrate that touch decreases the ambiguity in a visual image. It has been previously found that visual perception of three-dimensional shape is subject to certain variations. These variations can be described by the affine transformation. While the visual system thus seems unable to capture the Euclidean structure of a shape, touch could potentially be a useful source to di...
متن کاملThe visual and haptic perception of natural object shape.
In this study, we evaluated observers' ability to compare naturally shaped three-dimensional (3-D) objects, using their senses of vision and touch. In one experiment, the observers haptically manipulated 1 object and then indicated which of 12 visible objects possessed the same shape. In the second experiment, pairs of objects were presented, and the observers indicated whether their 3-D shape ...
متن کاملEfficient computation via sparse coding in electrosensory neural networks.
The electric sense combines spatial aspects of vision and touch with temporal features of audition. Its accessible neural architecture shares similarities with mammalian sensory systems and allows for recordings from successive brain areas to test hypotheses about neural coding. Further, electrosensory stimuli encountered during prey capture, navigation, and communication, can be readily synthe...
متن کاملGlobal shape coding for motion-defined radial-frequency contours
The visual system is highly skilled at recovering the shape of complex objects defined exclusively by motion cues. But while low-level and high-level mechanisms involved in shape-from-motion have been studied extensively, intermediate computational stages remain poorly understood. In the present study, we used motion-defined radial-frequency contours--or motion RFs--to probe intermediate stages...
