要旨 |
Interacting with objects in three-dimensional (3D) space often requires the brain to determine their spatial pose (position and orientation) from visual signals. In 3D space, an object’s pose has six degrees of freedom – three specifying position and three specifying orientation. Conversely, retinal images are 2D and thus have only three degrees of freedom – two positional and one orientational. The missing three degrees of freedom must be inferred by the brain, making the construction of 3D visual representations a complex, but fundamental task. In this talk, I will discuss experiments we are conducting in the caudal intraparietal area (CIP) of the macaque monkey to elucidate the neural coding of 3D object pose.
