Abstract During states of anxiety, fundamental threat circuitry in the brain can increase heart rate via alterations autonomic balance (increased sympathetic activity and parasympathetic withdrawal) may serve to promote interoceptive integration awareness cardiac signals. Moreover, evidence indicates pathological anxiety could be associated with increased communication between heart. Yet, this phenomenon remains not well understood. For instance, studies area have been conducted within confines tightly controlled experimental paradigms. Whether impacts brain-heart outside such settings, relatively more naturalistic contexts, is less clear. Here, we used a suspenseful movie fMRI paradigm study induced (n = 29 healthy volunteers; Caltech Conte dataset; Kliemann et al., 2022). We predicted that responses across an anxiety-relevant “defensive response network” (amygdala, hypothalamus, periaqueductal gray, bed nucleus stria terminalis, dorsomedial prefrontal cortex, ventromedial subgenual anterior cingulate, insula; Abend 2022) would show coherence as participants watched clip compared non-suspenseful clip. Counter our predictions, found decreased during namely amygdala-prefrontal circuitry. suggest these underpinned by withdrawal and/or movie-watching.

Coordinated interactions between the central and autonomic nervous systems are crucial for survival due to inherent propensity human behavior make errors. In our ever-changing environment, when individuals mistakes, these errors can have life-threatening consequences. response errors, specific reactions occur in both brain activity heart rate detect correct Specifically, there two brain-related indicators of error detection awareness known as error-related negativity positivity. Conversely, cardiac deceleration denotes a momentary slowing following an error, signaling response. However, what is connection during processing? this review, we discuss functional neuroanatomical connections markers processing, exploring experimental conditions which they covary. Given current limitations available data, future research will continue investigate neurobiological factors governing brain-heart interaction, aiming utilize them combined assessing cognitive control healthy pathological conditions.

Emotions, bodily sensations and movement are integral parts of musical experiences. Yet, it remains unknown i) whether emotional connotations structural features music elicit discrete ii) these culturally consistent. We addressed questions in a cross-cultural study with Western (European North American, n = 903) East Asian (Chinese, 1035). precented participants silhouettes human bodies asked them to indicate the regions whose activity they felt changing while listening pieces varying acoustic qualities. The resulting sensation maps (BSMs) varied as function qualities songs, particularly limb, chest, head regions. Music-induced emotions corresponding BSMs were replicable across subjects. clustered similarly cultures, cluster structures similar for self-reports experience. consistently associated emotion ratings music-induced cultures. These results highlight importance subjective experience demonstrate consistent associations between features, emotions, distant

Abstract Uncertainty about potential future threats and the associated anxious anticipation represents a key feature of anxiety. However, neural systems that underlie subjective experience threat under uncertainty remain unclear. Combining an uncertainty-variation paradigm allows precise modulation level momentary arousal during functional magnetic resonance imaging (fMRI) with multivariate predictive modeling, we train brain model accurately predicts intensity test it across 9 samples (total n = 572, both gender). Using publicly available datasets, demonstrate whole-brain signature specifically is not sensitive in predicting pain, general or unspecific emotional autonomic arousal. The also functionally spatially distinguishable from representations fear negative affect. We develop sensitive, generalizable, specific neuroimaging marker for uncertain can facilitate development.

The intricate role of the autonomic nervous system (ANS) in regulating cardiac physiology has long been recognized. Aberrant function ANS is central to pathophysiology cardiovascular diseases. It stands reason, therefore, that neuroscience-based therapeutics hold great promise treatment diseases humans.

Abstract It has been shown that cessation of intensive sensory stimulation is associated with a transient increase in functional inhibition the cortical areas. However, electrophysiological correlates this post-stimulus human brain have not thoroughly investigated. To investigate inhibition, we analyzed magnetoencephalogram (MEG) recorded at rest and after visual varying intensity (high-contrast gratings drifting slow, medium, or high rate) 25 healthy women aged 18–40 years. We condition- intensity-related changes MEG parameters sensitive to inhibition: periodic alpha-beta power, peak alpha frequency (PAF), 1/f aperiodic slope. also investigated association these sensitivity avoidance assessed by questionnaire. evaluate influence hormonal status on studied parameters, participants were examined twice, during follicular luteal phases menstrual cycle (MC). Regardless MC phase, increasing drift rate resulted proportional posterior PAF, negative shift (1/f) slope power spectrum high-frequency range. Compared rest, periods characterized higher more areas, widespread beta power. While drift-rate-dependent modulations correlated, PAF did correlate either them. A greater intensity-dependent predicted subjective sensitivity/avoidance, suggesting stronger regulatory top-down modulation cortex individuals heightened sensitivity. Our results show several concordantly indicate enhancement preceding stimulation. may share some common mechanisms, reflect distinct aspect inhibitory regulation. inform potential inhibition-based biomarkers for clinical translational research.
