Abstract: The human visual system is able to distinguish naturally occurring categories with exceptional speed and accuracy. At the same time, it exhibits substantial plasticity, permitting the seamless and fast learning of entirely novel categories. Here we investigate the interplay of these two processes by asking how category selectivity emerges and develops from initial to extended category learning. For this purpose, we combine a rapid event-related MEG adaptation paradigm, an extension of fMRI adaptation to high temporal resolution, a novel spatiotemporal ...
