The elusive neural signature of emotion regulation capabilities: evidence from a large-scale consortium

This study examines the relationship between neural activation during reappraisal tasks and individual differences in emotion regulation, finding no shared overlap across three measures and highlighting methodological challenges in fMRI research.

Associative emotional memory encoding: Insights from network stability analysis of an fMRI-driven bilinear dynamics

The paper analyzes neuronal dynamics during emotional memory encoding using fMRI data, finding that emotional conditions enhance memory through increased hippocampus-amygdala coupling and network connectivity.

Genomic analysis of intracranial and subcortical brain volumes yields polygenic scores accounting for variation across ancestries

The paper conducts GWAS on brain volumes, identifies genetic loci, and develops polygenic scores with cross-ancestry predictive ability and causal links to neuropsychiatric disorders.

Emotional information facilitates or disrupts memory integration through distinct hippocampal processes of reactivation and connectivity

This study investigates how emotional information affects memory integration through distinct hippocampal processes of reactivation and connectivity during encoding and retrieval.

Emotional tagging retroactively promotes memory integration through rapid neural reactivation and reorganization

This study shows emotional tagging enhances memory for neutral events through rapid neural reactivation and reorganization in the hippocampus and neocortex.

Non-REM sleep in major depressive disorder

This study analyzes non-REM sleep EEG features in MDD patients and finds subtle alterations linked to medication and memory consolidation.

Brain preparedness: The proactive role of the cortisol awakening response

The paper investigates the cortisol awakening response (CAR) and its role in brain preparedness, finding that CAR predicts improved neural efficiency and working memory performance.

Hippocampal-medial prefrontal event segmentation and integration contribute to episodic memory formation

The paper examines how hippocampal and medial prefrontal cortex activity during movie watching relates to episodic memory formation by analyzing activation and connectivity patterns.

Durable memories and efficient neural coding through mnemonic training using the method of loci

This study shows that mnemonic training improves durable memory formation by reducing task-based brain activation and enhancing consolidation.

Probing the neural dynamics of mnemonic representations after the initial consolidation

This study investigates how retrieval and suppression affect established memories 24 hours after learning using fMRI, finding that retrieval strengthens memories while suppression has a modest negative effect.

Dynamic transitions between neural states are associated with flexible task-switching during a memory task

The paper investigates neural state transitions during task-switching in a memory task and finds that task-switching leads to weaker current task representations and poorer performance.

Overlapping connectivity gradients in the anterior temporal lobe underlie semantic cognition

The paper identifies two overlapping functional connectivity gradients in the anterior temporal lobe that predict distinct aspects of semantic cognition.

Common neural and transcriptional correlates of inhibitory control underlie emotion regulation and memory control

The paper identifies a shared neural network and gene set involved in inhibitory control across emotion regulation and memory control using neuroimaging and transcriptomic data.

The influence of transcranial magnetic stimulation of the medial prefrontal cortex on emotional memory schemas

This study uses TMS to perturb the medial prefrontal cortex and examines its effect on emotional memory schemas in healthy volunteers, finding reduced false recognition of negative stimuli.

The role of hippocampal spatial representations in contextualization and generalization of fear

This study investigates how hippocampal spatial representations influence fear generalization and contextualization in humans using fMRI and virtual reality.

Differences in strategic abilities but not associative processes explain memory development

The paper investigates how strategic and associative memory components develop across childhood, adolescence, and adulthood using fMRI, finding that strategic abilities, not associative processes, explain memory differences.

The functional organisation of the hippocampus along its long axis is gradual and predicts recollection

This study uses resting-state fMRI data to show the hippocampus's functional organisation along its long axis is gradual, not segregated, and predicts recollection memory better than parcellation-based approaches.

Neural dynamics of accumulating and updating linguistic knowledge structures

This study investigates how linguistic associative knowledge is acquired through generalization and integration across learning experiences, identifying brain regions involved in knowledge updating and retrieval.

Cued reactivation during slow-wave sleep induces connectivity changes related to memory stabilization.

The paper analyzes how auditory cues during slow-wave sleep affect brain network connectivity and memory stabilization.

Brain scans from 21297 individuals reveal the genetic architecture of hippocampal subfield volumes

This study identifies 15 genome-wide significant loci associated with hippocampal subfield volumes in 21,297 individuals, revealing distinct genetic determinants for different subfields.

Eye-movement intervention enhances extinction via amygdala deactivation

This study shows that eye-movement interventions reduce fear recovery by temporarily deactivating the amygdala during extinction learning, similar to working memory tasks.

2D:4D and spatial abilities: From rats to humans

This study confirms the link between 2D:4D ratio and spatial performance in rats and humans, and identifies brain correlates in humans.
