Visual cortex: the continuing puzzle of area V2.
Surprisingly little is known about the role of V2 in visual processing. A recent study found that the responses of V2 neurons to pairs of angled lines could be predicted from their responses to the individual line components. A simple analysis shows how these neurons may simply sum the responses from one or more orientation selective V1 neurons.
