Data mining the functional architecture of the brain's circuitry

Authors: Adam S. Charles

arXiv

The brain is a highly complex organ consisting of a myriad of subsystems that flexibly interact and adapt over time and context to enable perception, cognition, and behavior. Understanding the multi-s...

Modeling arousal potential of epistemic emotions using Bayesian information gain: Inquiry cycle driven by free energy fluctuations

Authors: Hideyoshi Yanagisawa, Shimon Honda

arXiv

Epistemic emotions, such as curiosity and interest, drive the inquiry process. This study proposes a novel formulation of epistemic emotions such as curiosity and interest using two types of informati...

Fast Two-photon Microscopy by Neuroimaging with Oblong Random Acquisition (NORA)

Authors: Esther Whang, Skyler Thomas, Ji Yi, Adam S. Charles

arXiv

Advances in neural imaging have enabled neuroscientists to study how large neural populations conspire to produce perception, behavior and cognition. Despite many advances in optical methods, there ex...

Differential Dynamic Causal Nets: Model Construction, Identification and Group Comparisons

Authors: Kang You, Gary Green, Jian Zhang

arXiv

Pathophysiolpgical modelling of brain systems from microscale to macroscale remains difficult in group comparisons partly because of the infeasibility of modelling the interactions of thousands of neu...

Distinguishing representational geometries with controversial stimuli: Bayesian experimental design and its application to face dissimilarity judgments

Authors: Tal Golan, Wenxuan Guo, Heiko H. Schütt, Nikolaus Kriegeskorte

arXiv

Comparing representations of complex stimuli in neural network layers to human brain representations or behavioral judgments can guide model development. However, even qualitatively distinct neural ne...

Hierarchical Bayesian inference for community detection and connectivity of functional brain networks

Authors: Lingbin Bian, Nizhuan Wang, Leonardo Novelli, Jonathan Keith, Adeel Razi

arXiv

Most functional magnetic resonance imaging studies rely on estimates of hierarchically organized functional brain networks whose segregation and integration reflect the cognitive and behavioral change...

A tutorial on electrogastrography using low-cost hardware and open-source software

Authors: Evgeniya Anisimova, Sameer N. B. Alladin, Styliani Tsamaz, Edwin S. Dalmaijer

arXiv

Electrogastrography is the recording of changes in electric potential caused by the stomach's pacemaker region, typically through several cutaneous sensors placed on the abdomen. It is a worthwhile te...
