Show moreThis book contains two main messages. First, an attempt is made to explain the diverse beneficial findings on cognition and mental health in the literature of meditation practices by the factor of breathing. In the respiratory vagal nerve stimulation model of contemplative practices (rVNS) specific respiratory patterns lead to changes in autonomic nervous system functioning that in turn produce changes in the central nervous system, which can be observed in a healthier cognitive and emotional balance. Second, there are two empirical chapters that show null-results on cognition with meditative movement (Tai Chi Chuan) and breathing interventions. The possible reasons for these lack of results are extensively discussed in this dissertation and put into a wider perspective within the scientific field. Show less

Show moreThe resting state connectivity of the dorsolateral prefrontal cortex with the left primary somatosensory cortex and the functional association of the inferior parietal cortex (IPC) with the right primary somatosensory cortex indicate better and poorer performance in cognitive control of language, respectively. Besides, the task based connectivity profiles of the clusters of the IPC elucidate that it is not the whole part of this brain area that is involved in cognitive control, in the fronto-parietal network, but only the rostral cluster of the IPC. Moreover, the unique functional associations of the middle and the caudal IPC evidence that the traditional categorization of brain areas does not accommodate the functions of these parts of the cortex; the connectivity patterns of the middle and the caudal IPC have highlighted another brain functional category beyond the classic definitions, as modulating cortical areas, the functional connectivity of which are disparate from parts of the cortex involved in task performance and brain areas related to the resting state functionality of the brain.
