许多促进内感受（身体部位的内部感觉）注意力/意识（IAA）的学科/传统训练从业者关注并意识到身体部位的内感受感觉体验。这种做法的影响已经在以前的成像研究，但仅限于大脑神经活动。在这里，我们第一次研究了这些练习对专家和新手的脊髓神经活动的影响。我们还试图澄清恒定和深呼吸的影响，在集中的做法，以避免走神，对IAA相关的脊髓神经活动的范例。受试者在两个会议上进行IAA任务，并没有深和恒定的呼吸模式。结果表明，神经活动的脊髓节段支配的关注身体区域增加专家（P = 0.04），当他们进行IAA，这种增加是显着较大的专家与新手在每个会话（P = 0.024）。IAA和专业知识对脊髓神经活动的显着影响与以前的报告一致，并详细说明了对大脑神经活动的类似影响。由于脊髓直接支配身体部位，结果可能表明，IAA在长期训练后对身体有即时（可能有益）的影响。
Many disciplines/traditions that promote interoceptive (inner sensation of body parts) attention/awareness (IAA) train practitioners to both attend to and be aware of interoceptive sensory experiences in body parts. The effect of such practices has been investigated in previous imaging studies but limited to cerebral neural activity. Here, for the first time, we studied the impact of these practices on the spinal neural activity of experts and novices. We also attempted to clarify the effect of constant and deep breathing, a paradigm utilized in concentration practices to avoid mind wandering, on IAA-related spinal neural activity. Subjects performed IAA tasks with and without a deep and constant breathing pattern in two sessions. Results showed that neural activity in the spinal segment innervating the attended-to body area increased in experts (P = 0.04) when they performed IAA and that this increase was significantly larger for experts versus novices in each of the sessions (P = 0.024). The significant effects of IAA and expertise on spinal neural activity are consistent with and elaborate on previous reports showing similar effects on cerebral neural activity. As the spinal cord directly innervates body parts, the results might indicate that IAA has an instantaneous (possibly beneficial) effect on the physical body after extended training.
