The neural bases of different levels of action understanding.

Many have recently questioned whether all levels of actions understanding, from lower kinematic levels to the higher goal or intention levels of action understanding, are processed in the action observation network (a network of neurons that are active during action execution and observation). A recent study by Wurm and Lingnau (J Neurosci 35: 7727-7735, 2015) gave evidence to the contrary, by showing that higher levels of action understanding are processed in the lateral occipitotemporal cortex. An important next step is to differentiate between the role of the lateral occipitotemporal cortex in processing the visual form of an observed action and the goal of an observed action.
