Concurrently pain is a significant disadvantage to an individual\u2019s life and for society. Neurally, the pain stimulus travels in the central nervous system, starting from nociceptive receptors and continuing through the spinal cord to the limbic parts of the brain and from there to the cortex. Various regions of the brain are activated depending on the stage of the pain. Instead, the experience of pain is different for every individual and it is influenced by several background factors.\nThe purpose of this master\u2019s thesis is to investigate how individual tendencies, especially temperament trait negative affect and avoidance and approach behaviour correlate with resting activity of the brain before and after the pain experience. The study had 18 female subjects (age range: 18\u201342 years) and their pain thresholds were determined before the actual measurements. The electrical activity of the brain was measured by magnetoencephalography (MEG). During the MEG measurement, pain was produced by brief electrical pain stimulus on the fingers of the subjects. Before and after pain stimuli, the brain resting activity and its change was measured by focusing on frequency of alpha rhythm. In addition to pain stimulation, subjects completed a temperament questionnaire (ATQ-SF) and a questionnaire measuring avoidance and approach behaviour (BIS- BAS 20). From these behavioural variables, we extracted the negative affectivity and the BIS-BAS predispositions for our study.\nThere was no significant change in alpha frequency between the two resting state measurements. Instead, the alpha frequency before pain experience was significantly associated with BAS reward responsiveness. Furthermore, a significant association was found between the negative affect subscale fear and the alpha frequency after pain experience. The results of our study suggest that individual tendencies are related to the resting state of human brain before and after pain experience.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-12-17T10:12:14Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-12-17T10:12:14Z (GMT).
