Asymmetry of spatial attention has long been described in both disease (hemispatial neglect) and healthy (pseudoneglect) states. Although right-hemisphere specialization for suggested, the exact neural mechanisms asymmetry have not deciphered yet. A recent functional magnetic resonance imaging study from our laboratory serendipitously revealed bihemispheric left-hemifield superiority activation a visuospatial attention-related network. Nineteen right-handed adult females participated two...

Discrepancies between expectations and outcomes, or prediction errors, are central to trial-and-error learning based on reward punishment, their neurobiological basis is well characterized. It not known, however, whether the same principles apply declarative memory systems, such as those supporting semantic learning. Here, we demonstrate with fMRI that brain parametrically encodes degree which new factual information violates prior knowledge beliefs-most prominently in ventral striatum,...

The ability to take action in the face of threat is highly diverse across individuals. What are neural processes that determine individual differences cope with danger? We hypothesized extent synchronization between amygdala, striatum, and medial prefrontal cortex (mPFC) would predict successful active coping performance. To test this, we developed a novel computer task based on principals Sidman avoidance. Healthy human participants learned through trial error move marker virtual game board...

We took snapshots of human brain activity with fMRI during retrieval realistic episodic memory over several months. Three groups participants were scanned a test either hours, weeks, or months after viewing documentary movie. High recognition accuracy hours decreased weeks and remained at similar levels In contrast, BOLD in retrieval-related set areas correctly remembered events was but significantly declined Despite this reduction, regions positively correlated only Hippocampal engagement...

We present a robotic embodiment experiment based on real-time functional Magnetic Resonance Imaging (rtfMRI). To our knowledge, this is the first time fMRI used as an input device to identify subject's intentions and convert them into actions performed by humanoid robot. The process, motor imagery, has allowed subjects located in Israel control HOAP3 robot France, experiencing whole through eyes of

Interest has been growing in the use of mindfulness meditation (MM) as a therapeutic practice, accumulating evidence highlights its potential to effectively address range mental conditions. While many fMRI studies focused on neural activation and functional connectivity during meditation, impact long-term MM practice spontaneous brain activity, expression resting state networks over time, remains unclear. Here, intrinsic network dynamics were compared between experienced meditators...

The ability to selectively attend speech within complex auditory environments is crucial for effective communication. influence of background music on verbal learning has been a subject debate in previous research. Background comprises specific elements that can involuntarily capture or divert attention away from the primary task. present study aimed investigate impact instrumental music—specifically tension, tension-resolution, and neutral segments—on acquisition later retention...

Interpretation of emotional context is a pivotal aspect understanding social situations. A critical component this process assessment danger levels in the surrounding, which may have direct effect on organism's survival. The limbic system has been implicated mediating assessment. In situations uncertainty, evaluation also call for greater involvement prefrontal cortex decision-making and planning an appropriate behavioral response. following study, morphed face images depicting expressions...

We present a robotic embodiment experiment based on real-time functional magnetic resonance imaging (rt-fMRI). In this study, fMRI is used as an input device to identify subject's intentions and convert them into actions performed by humanoid robot. The process, motor imagery, has allowed four subjects located in Israel control HOAP3 robot France, relatively natural manner, experiencing the whole through eyes of Motor imagery or movement left hand, right legs were motions left, right, walk...

Are specific distributed coactivations in the brain during memory retrieval a signature of outcome? Here we show that this is indeed case. Widespread networks were reported to be involved long-term episodic memories. Although functional coactivation among particular regions occurs retrieval, it unknown what extent contributes accuracy and confidence recollection. In study set out explore question. Participants saw narrative documentary movie. A week later they underwent an fMRI scan which...

Abstract Decision-making studies have implicated the ventromedial prefrontal cortex (vmPFC) in tracking value of rewards and punishments. At same time, fear-learning pointed to a role area updating previously learned cue–outcome associations. To disentangle these accounts, we used reward reversal-learning paradigm functional magnetic resonance imaging study 18 human participants. Participants first that one two colored squares (color A) was associated with monetary reward, whereas other B)...

Accumulated evidence points toward a long-axis functional division of the hippocampus, with its anterior part primarily associated emotional processes and posterior navigation cognition. It is yet unclear, however, how connectivity between areas along hippocampal longitudinal axis other brain regions differ, they are affected by age. Applying an anatomically driven general linear model-based analysis on large database resting-state fMRI data, we demonstrate that independent age, hippocampus...

Abstract Hemispheric lateralization of emotional processing has long been suggested, but its underlying neural mechanisms have not yet defined. In this functional magnetic resonance imaging study, facial expressions were presented to 10 right-handed healthy adult females in an event-related visual half-field presentation paradigm. Differential activations fearful versus neutral faces observed the amygdala, pulvinar, and superior colliculus only for left hemifield. Interestingly, hemifield...

Episodic memory is typically studied under conditions that treat participants as passive agents. Here we sought to explore how actively engaging in ongoing naturalistic occurrences affects long-term episodic memory. Participants viewed 40 short movie clips depicted a protagonist conversed with the participants. In each clip, they were either offered chance (supposedly) determine clip's continuation (active condition), or let computer decide for them (passive condition). returned two days one...

Preferences profoundly influence decision-making and are often acquired through experience, yet it is unclear what role conscious awareness plays in the formation persistence of long-term preferences to extent they can be altered by new experiences. We paired visually masked cues with monetary gains or losses during a task. Despite being unaware cues, subjects were influenced their predictive values over successive trials task, also revealed strong preference for appetitive aversive...

A young woman was filmed during 2 d of her ordinary life. few months and then again a years later she tested for the memory experiences in those days while undergoing fMRI scanning. As time passed, came to accept more false details as true. After months, activity network considered subserve autobiographical correlated with confidence rather than accuracy. years, mainly regions temporal pole displayed this pattern. These results might reflect slow process increased reliance on schemata at expense

Attention deficit hyperactivity disorder (ADHD) has been associated primarily with executive function deficits. Emerging findings suggest, however, that procedural learning may be compromised as well. To this effect, we recently showed feedback-based is selectively impaired in ADHD, results coincide dopaminergic alterations ADHD. Key questions, remain unresolved, among which are the conditions improve Here examined probabilistic during engage and declarative systems to different degrees,...

Abstract The effects of background music on learning and memory are inconsistent, partially due to the intrinsic complexity diversity music, as well variability in perception preference. By stripping down musical harmony its building blocks, namely discrete chords, we explored their formation unfamiliar word-image associations. Chords, defined two or more simultaneously played notes, differ number tones inter-tone intervals, yielding varying degrees harmonic complexity, which translate into...
