Disentangling presentation and processing times in the brain

Laurent Caplette, Robin A.A. Ince, Karim Jerbi, Frédéric Gosselin
2020 NeuroImage  
Consequently, information reaching our eyes at different moments is processed in the brain together.  ...  Here, we introduce a novel reverse correlation paradigm that allows us to uncover with millisecond precision the processing time course of specific information received on the retina at specific moments  ...  , possibly in part because the distinction between 58 stimulus presentation time and processing time is not often discussed or appreciated (but 59 Experimental design 161 Each participant came to the  ...

Probing Brain Activation Patterns by Dissociating Semantics and Syntax in Sentences

Shaonan Wang, Jiajun Zhang, Nan Lin, Chengqing Zong
2020 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
The relation between semantics and syntax and where they are represented in the neural level has been extensively debated in neurosciences.  ...  Then we associate these disentangled feature vectors with brain imaging data to explore brain representation of semantics and syntax.  ...  Acknowledgments The research work has been funded by the Intelligent Science and Technology  ...

Disentangling craving‐ and valence‐related brain responses to smoking cues in individuals with nicotine use disorder

2021 Addiction Biology  
Here, we investigated the influence of emotional valence on key addiction brain areas by disentangling craving- and valence-related brain responses with parametric modulators in 32 smokers.  ...  For one of the suggested key regions for addiction, the amygdala, we observed significantly stronger brain responses to the valence aspect of the presented images than to the craving aspect.  ...  ACKNOWLEDGEMENTS The authors thank all volunteers for participating in this study.

When Errors Are Rewarding

E. R. A. de Bruijn, F. P. de Lange, D. Y. von Cramon, M. Ullsperger
2009 Journal of Neuroscience  
The results demonstrate a clear distinction between error and reward processing in the human brain.  ...  We used neuroimaging to disentangle brain activations related to error and reward processing, by manipulating the social context (cooperation or competition).  ...  The current study aimed at using the different aspects of cooperative and competitive contexts to truly disentangle error and reward processes in the human brain.  ...
