Toward an Understanding of the Neurofunctional Dissociation between Animal and Tool Concepts: A Graph Theoretical Analysis

Kaoutar Skiker, Mounir Maouene
2015 Journal of Statistical Science and Application  
Here, we address this question from a network perspective suggesting that the neural distinction between animals and tools might reflect the differences in their structural semantic networks.  ...  However, the origin of this neurofunctional distinction for processing animal and tool concepts remains still unclear.  ...  Animal concepts have more shared features that are highly correlated and thus evoke activation in both posterior and anterior temporal areas for recognizing the domain and the identity of objects, respectively  ...

The dissociations of visual processing of "hole" and "no-hole" stimuli: An functional magnetic resonance imaging study

Qianli Meng, Yan Huang, Ding Cui, Lixia He, Lin Chen, Yuanye Ma, Xudong Zhao
2018 Brain and Behavior  
A "Global-first" topological approach proposed that the first step in object representation was to extract topological properties, especially whether the object had a hole or not.  ...  However, neuroimaging studies showed that the temporal lobe (IT), which lied at a late stage of ventral pathway, was involved as a dedicated region.  ...  However, in the perspective of classic visual pathways, the anterior temporal lobe (ATL) lied at the late stage of the ventral pathway, and thus, it appeared paradoxical that the ATL would be the key region  ...

Central mechanisms of odour object perception

Jay A. Gottfried
2010 Nature Reviews Neuroscience  
Recent evidence indicates that the identification, categorization and discrimination of olfactory stimuli rely on the formation and modulation of odour objects in the piriform cortex.  ...  Convergent findings from human and rodent models suggest that distributed piriform ensemble patterns of olfactory qualities and categories are crucial for maintaining the perceptual constancy of ecologically  ...  Acknowledgements The author would like to thank the members of the Gottfried Laboratory for helpful comments and suggestions.  ...

Marc L. Jouandet, Mark Jude Tramo, Daniel M. Herron, Allison Hermann, William C. Loftus, Josh Bazell, Michael S. Gazzaniga
1989 Journal of Cognitive Neuroscience  
Cortical regions which were discontinuous in the plane of section (e.g. the anterior temporal lobe in the coronal plane) were bridged using four reference points (Figure 15c, d).  ...  In all six human brainprints, the bulk of the cortex lies buried within sulci. For the in vivo maps, this was most prominent in the parietal lobe (64-70%) and least in the temporal lobe (50-58%).  ...
