Rethinking pre-training: cognitive load implications for learners with varying prior knowledge

Frontiers in Psychology
This study examines how prior knowledge and pre-training relate to cognitive load during problem-solving. Grounded in cognitive load theory, it investigates whether pre-training facilitates learning by reducing cognitive load or imposes redundant ...

What does germane load mean? An empirical contribution to the cognitive load theory

Frontiers in Psychology, 2014
While over the last decades, much attention has been paid to the mental workload in the field of human computer interactions, there is still a lack of consensus concerning the factors that generate it as well as the measurement methods that could reflect

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety

Advanced Science, EarlyView.
This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

Iron Oxide Nanozyme as Reactive Oxygen and Nitrogen Species Scavenger to Regulate Microglial Homeostasis in Stroke

Advanced Science, EarlyView.
6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...

Neuronal Cholesterol Deficiency Mediated by Astrocytic SREBP2 Downregulation Leads to Postoperative Cognitive Dysfunction Through Impairment of Hippocampal Synaptic Plasticity and Excitatory Synaptic Transmission

Advanced Science, EarlyView.
The results showed that the reduction of plasma 24‐hydroxycholesterol (24‐OHC) was related to the cognitive decline in elderly surgical patients. Neuroinflammation induced by anesthesia and surgery significantly downregulated SREBP2 in hippocampal reactive astrocytes, resulting in reduced cholesterol synthesis.

Microglial Membranes Wrapped Ultrasmall Medium‐Entropy Ru Single‐Atom Nanozyme: Enhanced Catalysis for Accelerating Inflammation/Redox Microenvironment Regulation in Intracerebral Hemorrhage

Advanced Science, EarlyView.
PtRhIr/Ru SAN@M nanozymes cross the blood–brain barrier and selectively accumulate in hemorrhagic brain regions. By mimicking multiple enzyme activities, they attenuate oxidative stress, modulate microglial polarization toward an anti‐inflammatory phenotype, inhibit ferroptosis, and promote neuronal repair.

Using virtual reality for enhancing neuroanatomy learning by optimizing cognitive load and intrinsic motivation

Computers & Education
This research investigates the effectiveness of virtual reality (VR) in enhancing neuroanatomy learning among medical students, focusing on optimizing cognitive load, intrinsic motivation, and user experience. A total of 77 s-year medical students participated in the study, which compared traditional video-based instruction with three VR conditions ...

H2S‐Releasing Aspirin Nanoparticles Alleviate Endometriosis and Associated Anxiety

Advanced Science, EarlyView.
Albumin nanoparticles loaded with an H2S‐releasing aspirin derivative (ACS14) hitchhiking neutrophils after intraperitoneal injection and preferentially accumulate in endometriosis lesions in mice. The treatment suppresses lesion growth by regulating PI3K/Akt and reduces inflammation by inhibiting NF‐κB.

Advancing Precision Nutrition Through Multimodal Data and Artificial Intelligence

Advanced Science, EarlyView.
Individual responses to food vary dramatically, challenging traditional dietary advice. This review explores how the unique genetic makeup, gut microbiome, and brain activity shape host metabolic health. We examine how artificial intelligence integrates these multimodal data to predict individualized dietary needs, moving beyond one‐size‐fits‐all ...
