The dorsal visual stream processes object orientation for action, but only for graspable objects. The lateral occipito-parietal junction shows orientation sensitivity specific to graspable items, not non-graspable ones.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Visual Perception

Background:

  • Distinct ventral (perception) and dorsal (action) visual streams are proposed.
  • Previous fMRI studies show ventral stream sensitivity to object identity, dorsal to orientation.
  • Dorsal stream orientation sensitivity may relate to visuomotor control for grasping.

Purpose of the Study:

  • To investigate if dorsal stream orientation sensitivity is specific to graspable objects.
  • To test the hypothesis that orientation changes affect affordances for action.

Main Methods:

  • Used fMRI adaptation paradigm with graspable and non-graspable stimuli.
  • Participants viewed stimuli in original or mirror-image orientations.
  • Analyzed brain activity in dorsal stream regions, specifically the lateral occipito-parietal junction (lOPJ).

Main Results:

  • The lOPJ showed sensitivity to orientation changes for graspable objects.
  • The lOPJ did not exhibit orientation sensitivity for non-graspable objects.
  • This indicates a specificity of orientation processing in the dorsal stream.

Conclusions:

  • Orientation sensitivity in the dorsal stream, particularly the lOPJ, is specific to graspable objects.
  • This specificity likely reflects the impact of orientation on object affordances for grasping.
  • Supports the role of the dorsal stream in visually guided action based on object properties.
