Tokyo, Dec. 16 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000060086) titled 'A Comprehensive Study on the Link Between Breathing Sensations, Emotions, and Pain, and Their Brain Mechanisms' on Dec. 16.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Double blind -all involved are blinded Control - Placebo

Primary Sponsor: Institute - Niigata University of Health and Welfare

Condition: Condition - chronic pain, affective disorder Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The aim of this study is to elucidate the mechanisms underlying the relationship between respiratory interoception and emotional and pain perception. Specifically, we will quantify respiratory interoceptive processes using multiple objective and subjective indices, including inspiratory load discrimination performance, tolerance to breathlessness (breath-hold task), and metacognitive metrics such as confidence ratings. We will then examine how these respiratory interoceptive measures relate to emotional and pain perception. Furthermore, by acquiring electroencephalography (EEG) and magnetic resonance imaging (MRI) data during task performance, we will identify brain regions specifically involved in respiratory interoceptive processing. Finally, by applying non-invasive brain stimulation to these regions, we will investigate the neural mechanisms that contribute to respiratory interoception as well as to emotional and pain perception. Basic objectives2 - Efficacy
