The recollection of episodic-autobiographical memories (EAMs) entails a complex temporal dynamic, from initial "construction" to subsequent "elaboration" of memories. While there is consensus that EAM retrieval involves a distributed network of brain regions, it is still largely debated which regions specifically contribute to EAM construction and/or elaboration. To clarify this issue, we conducted an Activation Likelihood Estimation (ALE) meta-analysis based on the Preferred Reporting Items for Systematic-Reviews and Meta-Analyses (PRISMA) method. We found common recruitment of the left hippocampus and posterior cingulate cortex (PCC) during both phases. Additionally, EAM construction led to activations in the ventromedial prefrontal cortex, left angular gyrus (AG), right hippocampus, and precuneus, while the right inferior frontal gyrus was activated by EAM elaboration. Although most of these regions are distributed over the default mode network, the current findings highlight a differential contribution according to early (midline regions, left/right hippocampus, and left AG) versus later (left hippocampus, and PCC) recollection. Overall, these findings contribute to clarify the neural correlates that support the temporal dynamics of EAM recollection.

Background: Peripartum depression (PPD) is a form of major depressive disorder (MDD) that begins during the peripartum period and poses a significant mental health challenge affecting 10 to 29% of women.
Objective: This systematic review and multimodal activation likelihood estimation (ALE) meta-analysis explored the distinct structural, functional, and metabolic features of the PPD brain as compared to female non-peripartum MDD.
Methods: For this purpose, we conducted a comprehensive literature search in PubMed, Embase and PsycINFO databases to identify peer-reviewed original studies investigating the neural correlates associated with PPD or fMDD.

Background: Functional magnetic resonance imaging (fMRI) studies examining emotional memory encoding often use event-related designs with stimuli in the form of words or pictures. Prior research has suggested differential hemispheric specialization for these stimulus types, yet no meta-analysis has directly compared the neural systems involved in each.
Methods: A meta-analysis was conducted using peer-reviewed, event-related fMRI studies.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder marked-among other features-by impairments in response inhibition, a complex cognitive process assessable through tasks that either involve conflict suppression (C tasks) or do not (no-C tasks). Previous research has linked impaired response inhibition in ADHD primarily to structural and functional abnormalities in fronto-striatal and fronto-parietal networks. However, it remains unclear how these neural circuits differentially support performance on C and no-C tasks in individuals with ADHD.

Two decades of task-based fMRI studies have revealed atypical task-related activation and hypoactivation patterns in Alzheimer's disease (AD) and mild cognitive impairment (MCI), implicating the impaired cognitive processing observed in these neurocognitive disorders. The current coordinate-based meta-analysis provides an updated picture of the pathophysiological neurocognitive mechanisms implicated in MCI and AD, which better controls for false positive findings. To pool and summarise these findings, we conducted activation likelihood estimation (ALE) meta-analyses on 90 eligible studies (N = 2824) with cluster-level family-wise error correction to compare AD/MCI and healthy controls (HC) on fMRI activity during cognitive tasks across four different domains.

Neurological networks involved in bilingual language control have been extensively investigated. Among the factors that influence bilingual language control, language balance has recently been proposed as a critical one. Nevertheless, it remains understudied how the neural basis of bilingual language control is affected by language balance.
