Appearance isn't everything: news on object representation in cortex.
How objects are represented in the visual system is one of the big questions in cognitive neuroscience. In this issue of Neuron, Mahon and colleagues present an intriguing study that suggests that properties of objects other than shape can influence the arrangement of object selectivities in visual areas. In the process, the study also points to important caveats regarding the ability of standard fMRI studies to make inferences about neuronal selectivity.
