The aim was to determine whether attentional focus (on the heart versus an external auditory stimulus) influences the magnitude of HEP responses and cortical activation patterns. The study included 43 media workers whose HEP signals were measured using magnetoencephalography (MEG). The analysis focused on the 200\u2013800 ms interval after a heartbeat and specifically examined differences between the right and left hemispheres as well as between different cortical regions.\n\nThe results indicated that attentional focus did not have a statistically significant effect on the magnitude of HEP responses. However, significant regional differences in cortical activation were observed, suggesting that HEP signals may reflect broader specialization within neural networks. Methodological challenges, such as the sensitivity of MEG signals and limitations in data processing, may have influenced the ability to detect effects.\n\nThis study provides valuable insights into the neural mechanisms of interoception and highlights the need to develop more precise measurement methods and expand research to larger and more diverse samples. The potential of HEP signals as biomarkers for studying workplace well-being and stress management is emphasized, though further research is needed to achieve a deeper understanding.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-06-04T07:02:19Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-06-04T07:02:19Z (GMT).
