Neuronal Representations Supporting Three-Dimensional Vision in Nonhuman Primates

Abstract: The visual system must reconstruct the dynamic, three-dimensional (3D) world from ambiguous two-dimensional (2D) retinal images. In this review, we synthesize current literature on how the visual system of nonhuman primates performs this transformation through multiple channels within the classically defined dorsal (where) and ventral (what) pathways. Each of these channels is specialized for processing different 3D features (e.g., the shape, orientation, or motion of objects, or the larger scene structure). D… Show more

“…The neurophysiological underpinnings of 3D motion perception is a topic of recurring interest (Rosenberg et al, 2023). The results here indicate that binocular receptive fields that jointly encode retinal speed and disparity information optimally support the estimation of 3D speed ( Figure 3A , bottom), especially at slow speeds (see Figure 3E ).…”

“…Clearly, humans can estimate 3D motion. And neurons that unambiguously select for 3D motion have recently been reported in area FST (Rosenberg et al, 2023; Thompson et al, 2023).…”

“…Although 3D visual processing shaped the evolution of the primate brain, 1 current understanding of 3D motion processing remains surprisingly limited compared with that of two-dimensional (2D) retinal-motion processing. 2 4 In part, this reflects that distinct cues signal 2D versus 3D motion, with 3D motion computations depending critically on the relationship between retinal-motion signals sensed by the two eyes. 5 8 …”
