Psychobiotics are modulators of the Microbiota-Gut-Brain Axis (MGBA) with promising benefits to mental health. Lifestyle behaviors established both health and MGBA. This randomized placebo-controlled clinical trial (NCT04823533) on healthy adults (N = 135) tested 4 weeks probiotic supplementation (Lactobacillus helveticus R0052 Bifidobacterium longum R0175). We assessed effects wellbeing, quality life, emotional regulation, anxiety, mindfulness interoceptive awareness. then analyzed if...
People often engage in episodic counterfactual thinking, or mentally simulating how the experienced past might have been different from it was. A commonly held view is that alternative event outcomes aids managing future uncertainty and improving behavior, for which simulations need to be remembered. Yet, phenomenological factors influencing memorability of remain unclear. To investigate this, we conducted two experiments using a paradigm where participants recalled autobiographical...
Neural representation refers to the brain activity that stands in for one's cognitive experience, and neuroscience, principal method studying neural representations is representational similarity analysis (RSA). The classic RSA (cRSA) approach examines overall quality of across numerous items by assessing correspondence between two matrices (RSMs): one based on a theoretical model stimulus other measured data. However, because cRSA cannot at level individual trials, it fundamentally limited...
Abstract Autonomous sensory meridian response (ASMR) describes the experience of a pleasant body sensation accompanied by feeling well‐being and relaxation in to specific audiovisual stimuli, such as whispers personal attention. Previous work suggests relationship between this with processing affective states; however, no research has explored differences interoception people experiencing ASMR those who do not. We hypothesized that is based on processing. To test this, we assessed group...
The capacity for goal-directed behavior relies on the generation and implementation of task sets. While sets are traditionally defined as mnemonic ensembles linking goals to stimulus-response mappings, we here asked question whether they may also entail information about difficulty: does level focus required performing a become incorporated within set? We addressed this by employing cued task-switching protocol, wherein participants engaged in two intermixed tasks with trial-unique stimuli....
When we perceive a scene, our brain processes various types of visual information simultaneously, ranging from sensory features, such as line orientations and colors, to categorical objects their arrangements. Whereas the role representations in predicting subsequent memory has been studied using isolated objects, impact on for complex scenes remains largely unknown. To address this gap, conducted an fMRI study which female male participants encoded pictures familiar (e.g., airport picture)...
Abstract Episodic counterfactual thinking (ECT) consists of imagining alternative outcomes to past personal events. Previous research has shown that ECT shares common neural substrates with episodic future (EFT): our ability imagine possible Both and EFT have been critically depend on the hippocampus, explored hippocampal engagement as a function perceived plausibility an imagined event. However, extent which hippocampus is modulated by during unknown. In this study, we combine two...
A widespread observation in the cognitive neuroscience of aging is that older adults show a more bilateral pattern task-related brain activation. These observations are based on inherently correlational approaches. The current study represents targeted assessment role bilaterality using repetitive transcranial magnetic stimulation (rTMS).
While some memories are vivid and detailed, others vague indistinct. Although this is a ubiquitous experience, the cognitive mechanisms underlying these differences not well understood. To investigate issue, in Experiment 1 (N=122), we examined how subjective feeling of memory vividness relates to perceptual (i.e., color brightness) semantic category stimulus) properties naturalistic images. Surprisingly, our findings showed that while moderately contribute visual memories, primary driver...
Abstract Visual mental imagery refers to our ability experience visual images in the absence of sensory stimulation. Studies have shown that can improve episodic memory. However, we limited understanding neural mechanisms underlying this improvement. Using electroencephalography, examined processes associated with retrieval previously generated images, focusing on how vividness at generation modulate processes. Participants viewed word stimuli referring common objects, forming a image each...
