Neuroimage 2021 Apr 17:118048. Epub 2021 Apr 17.

Department of Brain and Cognitive Engineering, Korea University, Republic of Korea; Department of Artificial Intelligence, Korea University, Republic of Korea. Electronic address:

Resting-state functional magnetic resonance imaging (rs-fMRI) has been widely adopted to investigate functional abnormalities in brain diseases. Rs-fMRI data is unsupervised in nature because the psychological and neurological labels are coarse-grained, and no accurate region-wise label is provided along with the complex co-activities of multiple regions. To the best of our knowledge, most studies regarding univariate group analysis or multivariate pattern recognition for brain disease identification have focused on discovering functional characteristics shared across subjects; however, they have paid less attention to individual properties of neural activities that result from different symptoms or degrees of abnormality.

Pulmonary insults exacerbate susceptibility to oral Listeria monocytogenes infection through the production of IL-10 by NK cells.

PLoS Pathog 2021 Apr 20;17(4):e1009531. Epub 2021 Apr 20.

Department of Immunology and Microbiology, University of Colorado Anschutz Medical Campus, Aurora, CO, United States of America.

Most individuals who consume foods contaminated with the bacterial pathogen Listeria monocytogenes (Lm) develop mild symptoms, while others are susceptible to life-threatening systemic infections (listeriosis). Although it is known that the risk of severe disease is increased in certain human populations, including the elderly, it remains unclear why others who consume contaminated food develop listeriosis. Here, we used a murine model to discover that pulmonary coinfections can impair the host's ability to adequately control and eradicate systemic Lm that cross from the intestines to the bloodstream.

The neural bases of resilient semantic system: evidence of variable neuro-displacement in cognitive systems.

Brain Struct Funct 2021 Apr 20. Epub 2021 Apr 20.

MRC Cognition and Brain Science Unit (CBU), University of Cambridge, Cambridge, CB2 7EF, UK.

The purpose of this study was to explore an important research goal in cognitive and clinical neuroscience: What are the neurocomputational mechanisms that make cognitive systems "well engineered" and thus resilient across a range of performance demands and to mild levels of perturbation or even damage? A new hypothesis called 'variable neuro-displacement' suggests that cognitive systems are formed with dynamic, spare processing capacity, which balances energy consumption against performance requirements and can be resilient to changes in performance demands. Here, we tested this hypothesis by investigating the neural dynamics of the semantic system by manipulating performance demand. The performance demand was manipulated with two levels of task difficulty (easy vs. Read More
