A visual stimulus at a particular location of the visual field may elicit a behavior while at the same time equally salient stimuli in other parts do not. This property of visual systems is known as selective visual attention (SVA). The animal is said to have a focus of attention (FoA) which it has shifted to a particular location. Visual attention normally involves an attention span at the location to which the FoA has been shifted. Here the attention span is measured in Drosophila. The fly is tethered and hence has its eyes fixed in space. It can shift its FoA internally. This shift is revealed using two simultaneous test stimuli with characteristic responses at their particular locations. In tethered flight a wild type fly keeps its FoA at a certain location for up to 4s. Flies with a mutation in the radish gene, that has been suggested to be involved in attention-like mechanisms, display a reduced attention span of only 1s.

Who is WithMe? EEG features for attention in a visual task, with auditory and rhythmic support.
Front Neurosci
January 2025
Department of Mathematics, University of Antwerp-Interuniversity Microelectronics Centre (imec), Antwerp, Belgium.
Introduction: The study of attention has been pivotal in advancing our comprehension of cognition. The goal of this study is to investigate which EEG data representations or features are most closely linked to attention, and to what extent they can handle the cross-subject variability.
Methods: We explore the features obtained from the univariate time series from a single EEG channel, such as time domain features and recurrence plots, as well as representations obtained directly from the multivariate time series, such as global field power or functional brain networks.
Social Activities and Cognitive Functioning Across Mid- and Late-Life: Evidence from China.

Background And Objectives: Social engagement is positively associated with cognitive health, yet the role of these activities across the life span and in different contexts remains under-explored. This study investigates the association between social activities and two domains of cognitive functioning among middle-aged and older Chinese individuals, a population with the highest number of dementia cases in the world. We pay particular attention to the unique role of activities in midlife on cognitive decline in the later years.

As the life span of companion animals increases and their owners' concern for their quality of life increases, interest in dental diseases has also gained attention. While many studies have explored oral diseases in general, research on small-breed dogs remains limited. Therefore, in this study, we analyzed various diseases that led to tooth extraction in small- and medium-breed dogs.

Introduction: Cognitive symptoms are common in Parkinson's Disease (PD), and digital interventions like telerehabilitation other an accessible way to manage these symptoms. This study aimed to assess the effectiveness of a Home-Based Computerized Cognitive Training (HB-CCT) program in individuals with PD using a pilot randomized cross-over design.

Ethnopharmacological Relevance: Traditional Chinese Medicine (TCM), as a longstanding therapeutic approach, offers unique advantages and potential in the treatment of liver cancer. Recent studies have highlighted its role in preventing liver cancer progression by modulating key signaling pathways. TCM's multi-component, multi-target, and multi-pathway mechanisms of action have garnered significant attention in the medical community for their ability to address complex diseases like liver cancer.
