Brain Sciences, Journal Year: 2025, Volume and Issue: 15(3), P. 220 - 220

Published: Feb. 20, 2025

Background/Objectives: This systematic review presents how neural and emotional networks are integrated into EEG-based emotion recognition, bridging the gap between cognitive neuroscience practical applications. Methods: Following PRISMA, 64 studies were reviewed that outlined latest feature extraction classification developments using deep learning models such as CNNs RNNs. Results: Indeed, findings showed multimodal approaches practical, especially combinations involving EEG with physiological signals, thus improving accuracy of classification, even surpassing 90% in some studies. Key signal processing techniques used during this process include spectral features, connectivity analysis, frontal asymmetry detection, which helped enhance performance recognition. Despite these advances, challenges remain more significant real-time processing, where a trade-off computational efficiency limits implementation. High cost is prohibitive to use real-world applications, therefore indicating need for development application optimization techniques. Aside from this, obstacles inconsistency labeling emotions, variation experimental protocols, non-standardized datasets regarding generalizability recognition systems. Discussion: These developing adaptive, algorithms, integrating other inputs like facial expressions sensors, standardized protocols elicitation classification. Further, related ethical issues respect privacy, data security, machine model biases be much proclaimed responsibly apply research on emotions areas healthcare, human–computer interaction, marketing. Conclusions: provides critical insight suggestions further field toward robust, scalable, applications by consolidating current methodologies identifying their key limitations.

Left Insula and Right Middle Temporal Gyrus Dominate Cortical Network Discriminating Arousal‐dependent Emotions

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Emotion processing is an integral part of everyone's life. The basic neural circuits involved in emotion perception are becoming clear, though the emotion's cognitive remains under investigation. Utilizing stereo-electroencephalograph with high temporal-spatial resolution, this study aims to decipher pathway responsible for discriminating low-arousal and high-arousal emotions. This involves 19 patients pharmacologically resistant epilepsy who participate a delayed match/mismatch sample task designed separately assess their ability discriminate between Three groups 11 brain subregions, dominant lateralization, compose network, which identified as arousal-dependent connection these leading by left insula right middle temporal gyrus, defines pathways emotions different arousals. Further, separated network patterns related emotional discrimination face-independent. Overall, gyrus emerge core components plays key roles dynamic course low- human brain.

Arousal and social anxiety but not the emotional category influence visual search performance when using task-irrelevant emotional faces

Visual Cognition, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 19

The goal of the present study was to test effects emotional arousal elicited by faces on visual search performance. In Experiment 1, facial expressions acted as distractors presented throughout task. 2, were only before We found that level can better describe their performance compared discrete categories. Exp1, with higher ratings more distracting, possibly because active inhibition is necessary solve However, in Exp2, levels resulted performance, they activate system, initiating readiness for action. also showed social anxiety diminishes attentional due its influence executive processing. This does not support involvement bottom-up biases maintenance many interventions seem target.

Eliciting Emotions: Investigating the Use of Generative AI and Facial Muscle Activation in Children’s Emotional Recognition

Big Data and Cognitive Computing, Journal Year: 2025, Volume and Issue: 9(1), P. 15 - 15

Published: Jan. 20, 2025

This study explores children’s emotions through a novel approach of Generative Artificial Intelligence (GenAI) and Facial Muscle Activation (FMA). It examines GenAI’s effectiveness in creating facial images that produce genuine emotional responses children, alongside FMA’s analysis muscular activation during these expressions. The aim is to determine if AI can realistically generate recognize similar human experiences. involves generating database 280 (40 per emotion) children expressing various emotions. For real faces from public databases (DEFSS NIMH-CHEFS), five were considered: happiness, angry, fear, sadness, neutral. In contrast, for AI-generated images, seven analyzed, including the previous plus surprise disgust. A feature vector extracted indicating lengths between reference points on face contract or expand based expressed emotion. then input into an artificial neural network emotion recognition classification, achieving accuracies up 99% certain cases. offers new avenues training validating algorithms, enabling models be trained with real-world data interchangeably. integration both datasets validation phases enhances model performance adaptability.

Differential fMRI neural synchrony associated with migraine during naturalistic stimuli with negative emotional valence

The Journal of Headache and Pain, Journal Year: 2025, Volume and Issue: 26(1)

Migraine is a common neurological disorder that impacts approximately 12% of the general population and characterized by moderate to severe headaches, nausea, mood changes, fatigue. It lower-level visual auditory processing, causing hypersensitivities lead heightened audiovisual multisensory integration. However, impact migraine on processing complex, stimuli still unclear. Additionally, may induce emotional arousal valence, though relative significance these factors remains unknown. The current study seeks identify how synchronous neural stimuli, this differs based valence stimulus. To do so, we collected functional magnetic resonance imaging data (fMRI) from 22 migraineurs 21 healthy controls during passive viewing three films differing valence. We identified that, in response negative high stimulus, group showed greater synchrony regions associated with integration, including bilateral posterior superior temporal gyrus (pSTG), parietal lobule (SPL), left middle (MTG). There were no significant differences between control groups positive neutral low stimuli. These findings suggest involves hypersensitivity movies as function where negative/aversive states drive Overall, research highlights distinct pathways through which emotion migraine.
