Sensory attenuation (i.e., the phenomenon whereby self-produced sensations are perceived as less intense compared to externally occurring ones) is among neurocognitive processes that help distinguishing ourselves from others. It thought be rooted in motor system (e.g., related intention and prediction), while role of body awareness, which necessarily accompanies any voluntary movement, this largely unknown. To fill gap, here we intensity, somatosensory evoked potentials, alpha-band...

Abstract Shared attention effects on learning and memory demonstrate that experiences are amplified when we not alone. Virtual reality poses new challenges to the study of co-presence. Above all, is coattending together with someone else’s avatar in an immersive VR setting comparable shared at a neural processing level? In present investigate for first time. We recorded mismatch negativities (MMN) during auditory roving paradigm, well-known index implicit perceptual learning. EEG responses...

Downregulating emotional overreactions toward threats is fundamental for developing treatments anxiety and post-traumatic disorders. The prefrontal cortex (PFC) critical top-down modulatory processes, despite previous studies adopting repetitive transcranial magnetic stimulation (rTMS) over this region provided encouraging results in enhancing extinction, no have hitherto explored the effects of stimulating medial anterior PFC (aPFC, encompassing Brodmann area 10) on threat memory...

Abstract From Kant to current perspectives in neuroaesthetics, the experience of beauty has been described as disinterested , i.e. focusing on stimulus perceptual features while neglecting self-referred concerns. At a neurophysiological level, some indirect evidence suggests that aesthetic appreciation might be associated with attentional enhancement and inhibition motor behaviour. To test this hypothesis, we performed three auditory-evoked potential experiments, employing consonant...

An important implication of several recent accounts motor control is that sensory feedback from self-generated movements relatively attenuated based on predictions issued by the agent's system. Such a relative attenuation information during actions has already been demonstrated in somatosensory domain. Here, we used functional magnetic resonance imaging (fMRI) and virtual reality-based setup to investigate potential brain responses realistic visual movement active vs. passive right-hand...

Is it true that we learn better what like? Current neuroaesthetic and neurocomputational models of aesthetic appreciation postulate the existence a correlation between learning. However, even though has been associated with attentional enhancements, systematic evidence demonstrating its influence on learning processes is still lacking. Here, in two experiments, investigated relationship preferences for consonance versus dissonance memorisation musical intervals chords. In Experiment 1, 60...

Neurocomputational models of cognition have framed aesthetic appreciation within the domain knowledge acquisition and learning, suggesting that might be considered as a hedonic feedback on successful perceptual learning dynamics. Such hypothesis, however, has never been empirically demonstrated yet. In order to investigate relationship between we measured EEG mismatch negativity (MMN) response more or less appreciated musical intervals, which is reliable index learning. To this end, MMN...

<b><i>Introduction:</i></b> Dissociative experiences are considered undesirable ketamine’s adverse events. However, they might be crucial for antidepressant effects, at least in some depression subtypes. Current understandings of therapeutic potentials converge on the so-called “relaxed prior hypothesis,” suggesting that glutamatergic blockage up-weights bottom-up surprising somatosensory/affective states. As a result, ketamine improves short-term plasticity by...

Can preferred music listening improve following attentional and learning performances? Here we suggest that this may be the case. In Experiment 1, non-preferred musical-piece listening, recorded electrophysiological responses to an auditory roving-paradigm. We computed mismatch negativity (MMN - difference between novel repeated stimulation), as index of perceptual learning, measured correlation trial-by-trial EEG fluctuations in Bayesian Surprise, a quantification neural attunement with...

Pursuing new knowledge in the entropic environment is pivotal for survival. However, dealing with uncertainty a costly challenge agent surrounded by stochastic sensory world, giving rise to different epistemic emotions, such as curiosity and anxiety. We recently proposed that aesthetic appreciation may have role of associating pleasant feedback update predictive representations. According this idea, its associated rewarding feeling could drive people seek over relationship between...

Prismatic adaptation (PA) results from repeated ballistic movements of the dominant arm toward visual targets while wearing prisms shifting field laterally (visuomotor prismatic training [VPT]). Following PA, subjects' pointing are deviated contralaterally to shift (aftereffect). The question whether spatial attention is also biased in same direction remains controversial scientific literature. To investigate effect PA on attention, we asked healthy participants perform a detection threshold...

Drawing from field theory, Gestalt therapy conceives psychological suffering and psychotherapy as two intentional phenomena, where unprocessed chaotic experiences seek the opportunity to emerge be assimilated through contact between patient therapist (i.e., intentionality of contacting). This therapeutic approach is based on therapist’s aesthetic experience his/her embodied presence in flow healing process because (1) perception beauty can provide with feedback assimilation experiences; (2)...

BackgroundNeuroimaging studies suggest that the inferior frontal operculum (IFO) is part of a neuronal network involved in facial expression processing, but causal role this region emotional face discrimination remains elusive.ObjectiveWe used cathodal (inhibitory) tDCS to test whether right (r-IFO) and left (l-IFO) IFO play discriminating basic emotions healthy volunteers. Specifically, we tested if two sites are selectively processing expressions conveying high or low arousal emotions....

Allocentric space representations demonstrated to be crucial improve visuo-spatial skills, pivotal in every-day life activities and for the development maintenance of other cognitive abilities, such as memory reasoning. Here, we present a series three different experiments: Experiment 1, Discovery sample (23 young male participants); 2, Neuroimaging replicating 3 (14 participants). In experiments, investigated whether virtual navigation stimulates ability form spatial allocentric...

Pathological embodiment (E+) is a specific contralesional delusion of body ownership, observed following brain damage, in which patients embody someone else's arm and its movements within their own schema whenever the 'alien' presented body-congruent position (i.e., 1st person perspective aligned with patient's shoulder). This disorder often associated spatial neglect, neurological syndrome are unaware stimuli (often left) space. Capitalizing on previous evidence demonstrating that prismatic...

Abstract E-learning activities are becoming more and common. Whilst it is well known that the physical presence of others motivates individuals to engage in perceptual learning tasks, systematic investigations comparing effects virtual co-presence on knowledge acquisition still scarce. Here we investigate explicit implicit learning. In Experiment 1 (discovery sample), retrieval accuracy a spatial memory task EEG indexes (mismatch negativity-MMN) were recorded when participants alone or...

Abstract Our body has evolved in terrestrial gravity and altered gravitational conditions may affect the sense of ownership (SBO). By means rubber hand illusion (RHI), we investigated SBO during water immersion parabolic flights, where unconventional is experienced. results show that remodulate relative weights visual, proprioceptive, vestibular inputs favoring vision, thus inducing an increased RHI susceptibility.
