Given the mounting evidence implicating posterior parietal cortex in action observation, and in particular that of manipulative actions, the aim of this study was to identify the parietal region, if any, that contributes to the processing of observed\u2010manipulative\u2010action numerosity, using the functional magnetic resonance imaging technique. Twenty\u2010one right\u2010handed healthy volunteers performed two discrimination tasks while in the scanner, responding to video stimuli in which an actor performed manipulative actions on colored target balls that appeared four times consecutively. The subjects discriminated between two small numerosities of either observed manipulative actions (\u201cAction\u201d condition) or colors of balls (\u201cBall\u201d condition). A significant difference between the \u201cAction\u201d and \u201cBall\u201d conditions was observed in occipito\u2010temporal cortex and the putative human anterior intraparietal sulcus (phAIP) area as well as the third topographic map of numerosity\u2010selective neurons at the post\u2010central sulcus (NPC3) of the left parietal cortex. A further ROI analysis of the group\u2010average data showed that at the single voxel level the latter area, more than any other parietal or occipito\u2010temporal numerosity map, favored numerosity of observed actions. These results suggest that phAIP processes the identity of observed manipulative actions, while neighboring NPC3 likely processes the numerosity of the identified observed actions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our faculty member Burcu Ay\u015fen \u00dcrgen published a new paper titled \u201cA parietal region processing numerosity of observed actions: An fMRI study\u201d\u00a0 in European Journal of Neuroscience.
