| Abstract | The relationship between ongoing brain interoceptive signals and emotional processes has been addressed only indirectly through external stimulus-locked measures. In this study, an internal body trigger (heart evoked potential, HEP) was used to measure ongoing internally triggered signals during emotional states. We employed high-density electroencephalography (hd-EEG), source reconstruction analysis, and behavioral measures to assess healthy participants watching emotion-inducing video-clips (positive, negative, and neutral emotions). Results showed emotional modulation of the HEP at specific source-space nodes of the fronto-insulo-temporal networks related to affective-cognitive integration. This study is the first to assess the direct convergence among continuous triggers of viscerosensory cortical markers and emotion through dynamic stimuli presentation. |
| Otra información | La relación entre las señales corporales y los procesos emocionales se ha abordado sólo de manera indirecta. En este estudio, una señal interna del cuerpo procesada a nivel cerebral (heart evoked potential, HEP) se moduló en función del contenido emocional de video-clips con alta carga emocional (positivos, negativos y neutrales). Análisis de fuente cerebral evidenciaron la activación de redes fronto-insulo-temporales asociadas a la modulación emocional del HEP. Este es el primer estudio que muestra una convergencia directa entre marcadores cerebrales cardiacos y el procesamiento de emociones. |
