Retinotopic biases in contextual feedback signals to V1 for object and scene processing.

Identifying the objects embedded in natural scenes relies on recurrent processing between lower and higher visual areas. How is cortical feedback information related to objects and scenes organised in lower visual areas? The spatial organisation of cortical feedback converging in early visual cortex during object and scene processing could be retinotopically specific as it is coded in V1, or object centred as coded in higher areas, or both. Here, we characterise object and scene-related feedback information to V1.

PAK3 pathogenic variant associated with sleep-related hypermotor epilepsy in a family with parental mosaicism.

Protein-activated kinases mediate spine morphogenesis and synaptic plasticity. PAK3 is part of the p21-activated kinases (PAKs) family of Ras-signaling serine/threonine kinases. Pathogenic variants in the X-linked gene PAK3 have been described in patients with neurodevelopmental syndromes.

ABA-auxin cascade regulates crop root angle in response to drought.

Enhancing drought resistance through the manipulation of root system architecture (RSA) in crops represents a crucial strategy for addressing food insecurity challenges. Abscisic acid (ABA) plays important roles in drought tolerance; yet, its molecular mechanisms in regulating RSA, especially in cereal crops, remain unclear. In this study, we report a new mechanism whereby ABA mediates local auxin biosynthesis to regulate root gravitropic response, thereby controlling the alteration of RSA in response to drought in cereal crops.

Blunted Ventral Striatal Reactivity to Social Reward Is Associated with More Severe Motivation and Pleasure Deficits in Psychosis.

Background And Hypothesis: Among individuals living with psychotic disorders, social impairment is common, debilitating, and challenging to treat. While the roots of this impairment are undoubtedly complex, converging lines of evidence suggest that social motivation and pleasure (MAP) deficits play a central role. Yet most neuroimaging studies have focused on monetary rewards, precluding decisive inferences.

Mapping resilience and co-occurring theoretical constructs in nurses: a scoping review protocol.

Objective: The aim of this scoping review is to map the concept of resilience and its measurement along with co-occurring theoretical constructs within nursing research using the COVID-19 pandemic as a critical date range for the current evidence.

Introduction: Resilience has a wide variety of definitions in research literature and is often measured through its co-occurring theoretical constructs. Nurse resilience is a key element in interventions targeting nurse well-being and has been tied to burnout and mental health.
