Research Abstract |
Our brain imaging studies of mental rotation demonstrated a pattern of brain activation consistent with the neural network model proposed by Ashizawa and Inui (2011). We then presented a generalized radial basis function (GRBF) network that can generate rotated views of novel objects as a form of view prediction. We also presented a hierarchical neural network model of the functions of inferior temporal cortex. This model can achieve not only view-independent object recognition but also object categorization based on view similarity. We further formulated a computational model of visual scene transformations to generate spatial imagery of novel places. In addition, a biologically plausible algorithm for grid cell computation is proposed that enables calculation of a homing vector to a specific location with a cognitive map. Finally, we identified the shared and distinct neural substrates for mental rotation and perspective taking.
