Chemosignals found in human body odors (BOs) convey information about a person's emotional state and elicit observable responses in others. While mindfulness typically enhances parasympathetic tone and reduces anxiety, little is known about how BOs modulate these effects. This study investigated how emotional and non-emotional human BOs influence autonomic nervous system activity - heart rate...
Dreams may be recalled after awakening from sleep following a defined electroencephalographic pattern that involves local decreases in low-frequency activity in the posterior cortical regions. Although a dreaming experience implies bodily changes at many organ, system, and timescale levels, the entity and causal role of such peripheral changes in a conscious dream experience are unknown. We...
This study reports on a multivariate complexity assessment for cardiovascular dynamics during REM sleep leading to a dream recall. Heart rate variability, as well as systolic and diastolic time interval variability series were gathered from eight volunteers during night sleep, and were considered input of a trivariate Multichannel Complexity Index (MCI) analysis. MCI is a recently proposed...
Uncovering the physiological correlates of dreams is one of the most ambitious aim of multidisciplinary neuroscientific research. Here we investigated Autonomic Nervous System (ANS) dynamics associated with a dream recall, with a particular focus on the complexity assessment on cardiovascular control. We recorded electrocardiogram and arterial blood pressure signals from eight healthy subjects...
