Abstract
Object control skills are one of the most important abilities in daily life. Knowledge of object manipulation is an essential factor in improving object control skills. Although males and females equally try to use object manipulation knowledge, their object control abilities often differ. To explain this difference, we investigated how structural brain networks in males and females are differentially organized in the tool-preferring areas of the object manipulation network. The structural connectivity between the primary motor and premotor regions and between the inferior parietal regions in males was significantly higher than that in females. However, females showed greater structural connectivity in various regions of the object manipulation network, including the paracentral lobule, inferior parietal regions, superior parietal cortices, MT+ complex and neighboring visual areas, and dorsal stream visual cortex. The global node strength found in the female parietal network was significantly higher than that in males but not for the entire object manipulation, ventral temporal, and motor networks. These findings indicated that the parietal network in females has greater inter-regional structural connectivity to retrieve manipulation knowledge than that in males. This study suggests that differential structural networks in males and females might influence object manipulation knowledge retrieval.
Highlights
We manipulate objects in our daily life for various purposes
This study aimed to investigate differences between males and females in structural connectivity to retrieve object manipulation knowledge
The structural network properties of males and females were assessed in the object manipulation network and its subnetworks
Summary
Object manipulation is the way we control objects (e.g., hammering action) [1]. Our knowledge of complex objects should be formed in the brain for stable object manipulation. Many functional magnetic resonance imaging (fMRI) studies have shown functional activations in tool-related brain regions for object manipulation, including the premotor cortex [9,10,11], inferior parietal cortex [11,12,13,14], superior parietal cortex [14, 15], medial fusiform gyrus [12, 16], and ventral and dorsal stream areas [12, 13, 15, 17]. Object manipulation can be represented by functional interactions between brain regions in the tool processing network
