Abstract In the last few years the involvement of the medial prefrontal cortex (mPFC) in memory processing has received increased attention. It has been shown to be centrally involved when we use prior knowledge (schemas) to improve learning of related material. With the mPFC also being one of the core hubs of the default mode network (DMN) and the DMN’s role in memory retrieval, we decided to investigate whether the mPFC in a schema paradigm acts independent of the DMN. We tested this with data...

How do we encode our continuous life experiences for later retrieval? Theories of event segmentation and integration suggest that the hippocampus binds separately represented events into an ordered narrative. Using an open-access functional Magnetic Resonance Imaging (fMRI) movie watching-recall dataset, we quantified neural similarities between separate events during movie watching and related them to subsequent retrieval of events as well as retrieval of sequential order. We demonstrate that d...

Externalizing behaviors in individuals with autism spectrum disorder (ASD) are often either reduced or elevated compared to healthy controls (HCs). This study investigated the moderating role of context in ASD by comparing 32 individuals with ASD to 40 HCs during a social and a non-social provocation task. Compared to HCs, individuals with ASD showed similar externalizing behavior in the social context. In the non-social context reactions after provocation were enhanced relative to non-provoking...

Memories are not stored as static engrams, but as dynamic representations affected by processes occurring after initial encoding or even consolidation. How the modulation of memory traces after their formation is reflected in the neural activity during subsequent retrieval is currently not well understood. Using fMRI in 27 healthy human participants, we probed how neural representations of associative memories are dynamically modulated by two behavioral techniques that can either strengthen or w...

Inhibitory control is crucial for regulating emotions and it may potentially also control memory retrieval. Here, we provide neurobiological and transcriptional evidence to link emotional and memory control, and thereby we identify neural networks and molecular mechanisms as potential targets for interventions. Based on MRI coordinates from 95 published fMRI studies, meta-analytic approaches revealed a common role of the right inferior parietal lobule embedded in a frontal-parietal-insular netwo...

Abstract In the last few years the involvement of the medial prefrontal cortex (mPFC) in memory processing has received increased attention. It is centrally involved when we use prior knowledge (schemas) to improve learning of new material. With the mPFC also being one of the core hubs of the default mode network (DMN) and the DMN’s role in memory retrieval, we decided to investigate whether the mPFC in a schema paradigm acts independently of the DMN. We tested this with data from a cross-sectio...

Children9s learning capabilities change while growing up. One framework that describes the cognitive and neural development of children9s growing learning abilities is the two-component model. It distinguishes processes that integrate separate features into a coherent memory representation (associative component) and executive abilities, such as elaboration, evaluation and monitoring, that support memory processing (strategic component). In an fMRI study using an object-location association para...

Abstract Probiotics are microorganisms that provide health benefits when consumed. In animals, probiotics reverse gut microbiome-related alterations in depression-like symptoms, in cognition, and in hormonal stress response. However, in humans, a causal understanding of the gut-brain link in emotion and cognition is lacking. Additionally, whether the effects of probiotics on neurocognition are visible only in presence of stress, remains unclear. We investigated the effects of a multispecies prob...

Abstract Personality is a central high-level psychological concept that defines individual human beings and has been associated with a variety of real-world outcomes (e.g., mental health and academic performance). Using 2 h, high resolution, functional magnetic resonance imaging (fMRI) resting state data of 984 (primary dataset N = 801, hold-out dataset N = 183) participants from the Human Connectome Project (HCP), we investigated the relationship between personality (five-factor model, FFM) and...
