Abstract Sensory signals from the body’s visceral organs (e.g. heart) can robustly influence perception of exteroceptive sensations. This interoceptive-exteroceptive interaction has been argued to underlie self-awareness by situating one’s perceptual awareness stimuli in context internal state, but studies probing cardiac influences on visual have yielded conflicting findings. In this study, we presented separate grating each subjects’ eyes as a classic binocular rivalry paradigm – measuring duration for which stimulus dominates perception. However, caused gratings “pulse” at specific times relative real-time electrocardiogram, manipulating whether pulses occurred during systole, when baroreceptors signal brain that heart contracted, or diastole are silent. The influential “Baroreceptor Hypothesis” predicts effect baroreceptive input should be uniformly suppressive. contrast, observed dominance durations increased systole-entrained stimuli, inconsistent with Baroreceptor Hypothesis. Further, show cardiac-dependent is preserved subjects who at-chance discriminating between and diastole-presented interoceptive task, suggesting our results not dependent conscious access heartbeat

Although it is generally held that gastrointestinal (GI) signals are related to emotions, direct evidence for such a link currently lacking. One of the reasons why internal milieu GI system poorly investigated because visceral organs difficult access and monitor. To directly measure influence endoluminal markers activity on emotional experience, we asked group healthy male participants ingest pill measured pH, pressure, temperature their tract while they watched video clips consistently induced disgust, fear, happiness, sadness, or control neutral state. In addition objective physiological activity, subjective ratings perceived emotions (i.e. gastric, respiratory cardiac) sensations were recorded, as well changes in heart rate (HR), variability (HRV) spontaneous eyes blinks non-gastric behavioral autonomic experience. We found when observed fearful disgusting clips, reported perceive not only cardiac but also gastric sensations, nausea. Moreover, there was clear relation between physiology stomach emotions. Specifically, displayed, more acidic feelings disgust fear; less happiness. Complementing results deep realm, stimuli significant increase HRV compared scenarios, together with decrease HR. Our findings suggest contribute unique states ingestible pills may open new avenues exploring deep-body

Abstract Recent studies suggest that the human body plays a critical role in episodic memory. Still, precise relationship between bodily self-consciousness (BSC) and memory formation of specific events, especially real-life contexts, remains topic ongoing research. The present study investigated BSC (EM) using immersive virtual reality (VR) technology. Participants were immersed an urban environment with naturalistic while their visuomotor feedback was manipulated three within-subjects conditions: Synchronous, Asynchronous, No-body. Our results show asynchronous not seeing one’s body, compared to synchronous feedback, decrease sense self-identification, self-location agency, presence. Moreover, navigating Asynchronous condition had detrimental impact on incidental event memory, perceptual details, contextual association, subjective remembering, consolidation. In contrast, participants No-Body only impaired egocentric spatial remembering at ten-day delay. We discuss these findings relation self-representation space during encoding. This sheds light complex interplay BSC, presence, processes, strengthens potential embodiment VR technology studying enhancing cognition.

Emotions are inherently complex - situated inside the brain while being influenced by conditions body and outside in world resulting substantial variation experience. Most studies, however, not designed to sufficiently sample this variation. In paper, we discuss what could be discovered if emotion were systematically studied within persons 'in wild', using biologically-triggered experience sampling: a multimodal deeply idiographic approach ambulatory sensing that links mind across contexts over time. We outline rationale for approach, challenges its implementation widespread adoption, set out opportunities innovation afforded emerging technologies. Implementing these innovations will enrich method theory at frontier of affective science, propelling contextually study into future.

Despite relevance of issue, no such studies are available women. To bridge this gap, tested whether synchronization avatar-participant respiration patterns influenced females' awareness. collected cardiac interoceptive measures, administered body (dis)satisfaction questionnaires, tracked participants' menstrual cycles via mobile app. Our approach allowed us to characterize women, explore relationships between cycle, interoception image. found was as crucial visual appearance eliciting feelings ownership held greater significance than any other cue with respect agency both women Moreover, positive correlation cycle days image concerns, negative sensibility dissatisfaction were found, confirming women's arises during last is associated interoception.

Beyond their vital role, recent developments have emphasized remarkable contribution of bodily signals to high-level brain functions. A direct route by which influence functioning is via modulation electrophysiological dynamics, turn influences integration processing emotional self-related information regulating our conscious experience.

Body image distortion (BID) is a crucial aspect of anorexia nervosa (AN), leading to body overestimation, dissatisfaction, and low self-esteem. BID significantly influences the onset, maintenance, relapse pathology. We assessed whether Full Illusion (FBI) using under normal-weight avatars' bodies affects perceptual schema estimations in both individuals with (AN) healthy controls (HC). After each embodiment procedure, we asked participants estimate width their hips (Perceptual Image Task) minimum aperture virtual door necessary pass through it (Body Schema Task). Additionally, rate avatars terms self-similarity, attractiveness, implicit disgust (i.e., pleasant/unpleasant odour). Whereas AN (N = 26) showed changes after embodying avatar, no were found HC 25), highlighting increased bodily self-plasticity AN. Notably, rated normal weight avatar as most similar real body, which was also considered least attractive repulsive. These ratings correlated severity. Furthermore, at explicit level, all reported feeling thinner than usual underweight avatar. Overall, our findings suggest that engages multiple sensory channels (from visual olfactory) components affective), offering potential targets for innovative non-invasive treatments aimed modifying flexible aspects representation.
