ABSTRACT Growing evidence suggests that conceptual knowledge influences emotion perception, yet the neural mechanisms underlying this effect are not fully understood. Recent studies have shown brain representations of facial categories in visual‐perceptual areas predicted by knowledge, but it remains to be seen if auditory regions similarly affected. Moreover, is clear whether these operate at a modality‐independent level. To address questions, we conducted functional magnetic resonance imaging study presenting participants with both and vocal emotional stimuli. This dual‐modality approach allowed us investigate effects on modality‐specific regions. Using univariate representational similarity analyses, found visual (middle lateral occipital cortices) (superior temporal gyrus) were understanding emotions for faces voices, respectively. Additionally, discovered also influenced supra‐modal superior sulcus. Dynamic causal modeling revealed network showing bottom‐up top‐down flows, suggesting complex interplay processing. These findings collectively indicate sensory‐perceptual likely shaped each individual's knowledge.

Emotions are central to human experience, yet their complexity and context-dependent nature challenge traditional laboratory studies. We present REELMO (REal-time EmotionaL responses MOvies), a novel dataset bridging controlled experiments naturalistic affective experiences. includes 1,060 hours of moment-by-moment emotional reports across 20 states collected during the viewing 60 full-length movies, along with additional measures personality traits, empathy, movie synopses, overall liking from 161 participants. It also features fMRI data volunteers recorded while watching Jojo Rabbit. Complemented by visual acoustic as well semantic content derived deep-learning models, provides comprehensive platform for advancing emotion research. Its high temporal resolution, rich annotations, integration enable investigations into interplay between sensory information, narrative structures, contextual factors in shaping experiences, study chronometry, mixed-valence states, psychological trait influences, machine learning applications (neuro)science.

Abstract Ambivalent feelings are a defining feature of awe, which has been understood as possible source its psychosocial benefits. However, due to the conventional unidimensional model affective valence, behavior and neural representation ambivalent during awe remain elusive. To address this gap, we combined awe-inducing virtual reality clips, electroencephalogram, deep learning-based dimensionality reduction technique ( N = 43). Behaviorally, ratings were precisely predicted by duration intensity feelings, not single valence-related metrics. In electrophysiological analysis, identified latent space for each participant sharing valence structures across individuals stimuli. these spaces, distinctly represented from positive negative ones, variability in their distinctiveness specifically ratings. Additionally, frontal delta oscillations mainly engaged differentiating representations. Our findings demonstrate that is fundamentally an experience reflected both activities. This work provides new framework understanding complex emotions underpinnings, with potential implications neuroscience relevant fields.
