AI Article Synopsis
- The study investigated how individual skills in face recognition relate to brain activity, specifically highlighting different responses in event-related potentials (ERPs), particularly the N170 component when recognizing faces.
- It found that individuals who are good at recognizing faces showed specific brain patterns for whole faces in the right hemisphere, while those who are bad at recognizing faces had a more generalized response, indicating different processing styles.
- The research suggests that the N170 component can help differentiate between holistic (whole face) and featural (specific features) processing in face recognition, depending on whether someone is a good or bad recognizer.
Article Abstract
Individual abilities in face recognition (good versus bad recognizers) were explored by means of event-related potentials (ERPs). The adaptation response profile of the N170 component to whole faces, eyes and mouths was used in order to highlight the crucial role of individual abilities in identity repetition processes for unfamiliar faces. The main point of this study is to underline the importance of characterizing the performance (bad or good) of the participants and to show that behaviorally selected groups might reveal neural differences. Good recognizers showed selective right hemisphere N170 repetition effects for whole faces and not for features. On the contrary, bad recognizers showed a general repetition effect not specifically related to faces and more pronounced processing for features. These findings suggest a different contribution of holistic and featural analysis in bad and good performers. In conclusion, we propose that the N170 might be used as a tool to tease apart face encoding processes as a function of individual differences.

The Holobiont concept in ruminant physiology - more of the same, or something new and meaningful to food quality, food security, and animal health?

The holobiont concept has emerged as an attempt to recognize and describe the myriad interactions and physiological signatures inherent to a host organism, as impacted by the microbial communities that colonize and/or co-inhabit the environment within which the host resides. The field acknowledges and draws upon principles from evolution, ecology, genetics, and biology, and in many respects has been "pushed" by the advent of high throughput DNA sequencing and, to a lesser extent, other "omics"-based technologies. Despite the explosion in data generation and analyses, much of our current understanding of the human and ruminant "holobiont" is based on compositional forms of data and thereby, restricted to describing host phenotypes via associative or correlative studies.

Background: Propensity score matching has become a popular method for estimating causal treatment effects in non-randomized studies. However, for time-to-event outcomes, the estimation of hazard ratios based on propensity scores can be challenging if omitted or unobserved covariates are present. Not accounting for such covariates could lead to treatment estimates, differing from the estimate of interest.

Background: Poor sleep quality may contribute to sarcopenia, but evidence remains sparse. This retrospective cross-sectional study investigated the association between subjective sleep quality and probable sarcopenia in a cohort of community-dwelling older adults enrolled in the Longevity Check-Up 8+ study.
Methods: Participants were asked about their sleep quality over the past month, with four possible options ("very good", "quite good", "quite bad", very bad").

Introduction: The endoscopic assisted release for cubital tunnel syndrome (CuTS) gained popularity in recent years with unclear long-term results. This study aims to evaluate long term results regarding functional and subjective outcomes after endoscopic assisted release for the CuTS.
Materials And Methods: Thirty one patients who have been treated by endoscopic assisted release for CuTS between 2006 and 2013 were followed up both clinically and with a questionnaire with a mean follow up of 152 months (range 120-204 months).
Mutual inclusivity improves decision-making by smoothing out choice's competitive edge.

Decisions form a central bottleneck to most tasks, one that people often experience as costly. Previous work proposes mitigating those costs by lowering one's threshold for deciding. Here we test an alternative solution, one that targets the basis of most choice costs: the idea that choosing one option sacrifices others (mutual exclusivity).
