Abstract

<p>Visual environmental changes dynamically, which causes change of object image reflected in the retina. However, we can identify an object from others effortlessly in daily life. This study focused on the change in viewing angle and aimed to elucidate the underlying neural processing for view-invariant object recognition. Inferotemporal cortex locates at the end of ventral cortical pathway which is critical for object recognition and discrimination. We have previously investigated the inferotemporal cell stimulus selectivity to the training object images and its change during object discrimination learning. In the present study, we generated response vectors using the firing frequency data of a cell population in inferotemporal cortex, and created object discrimination classifiers by training with the set of vectors with machine learning algorithm. Furthermore, we proposed a method with much higher temporal resolution to visualize the formation process of view-invariant object recognition, by shortening analysis window.</p>
