“…Conversely, HEP amplitude is reduced in depression (Terhaar et al, 2012), consistent with decreased bodily awareness, alexithymia (i.e. inability to experience emotions), and blunted emotional reactivity found in depressed patients (Bylsma et al, 2008; Imbault and Kuperman, 2018).…”

Nightmares are characterized by the experience of strong negative emotions occurring mainly during REM sleep. Some people suffer from nightmare disorder, which is defined by the repeated occurrence of nightmares and by significant distress in wakefulness. Yet, whether frequent nightmares relate to a general increase in emotional reactivity or arousal during sleep remains unclear. To address this question, we recorded heartbeat-evoked potentials (HEPs) during wakefulness, NREM and REM sleep in patients with nightmare disorder and healthy participants. The HEP represents a cortical (EEG) response to the heartbeat and indexes brain-body interactions, such as interoceptive processing and intrinsic levels of arousal. HEP amplitude is typically increased during states of high emotional arousal and motivation, and is decreased in depression. Here we compared the amplitude of HEPs between nightmare patients and healthy controls separately during AWAKE, NREM, REM periods, and found higher HEP amplitude in nightmare patients compared to healthy controls over a cluster of frontal regions only during REM sleep. This effect was not paralleled by any group difference in cardiac control measures (e.g. heart rate variability, interbeat interval). These findings corroborate the notion that nightmares are essentially a REM pathology and suggest that increased emotional arousal during REM sleep, as measured by HEP, is a physiological condition responsible for frequent nightmares. This result also supports that HEP may be used as a biomarker of increased emotional and sensory processing during REM sleep in these patients.

“…Conversely, healthy individuals tend to adapt to any given context. In contrast, depressed individuals tend to have a weaker, blunted response even to extreme positive and negative stimuli as opposed to healthy individuals (Imbault & Kuperman, 2018).…”

Depression is a leading emotional disorder among college students, affecting their general well-being, motivation, and academic performance. Stress reactivity and its trajectory over time is a well-known marker of depression. Yet, there is debate on how this trajectory would look like in an ecological setting. A leading hypothesis is that of the Emotion Context Insensitivity (ECI) framework, which states that depressed individuals experience a reduced reactivity to emotional cues and less recovery from stressful events. On the basis of ECI's assumption, the present study investigates trajectories of stress, negative, and positive affect in a sample of 188 college students. Participants were screened for depression and monitored for 6 days up to the moment of the exam, during the exam, and immediately after the exam. A multilevel modeling approach was used to examine outcome trajectory over time. The findings showed that students with higher depression levels have a different exam and stress experience from their peers. Students with higher depression did not grow as much as their less depressed peers in stress and negative affect levels as the moment of the exam approached. Moreover, their stress and negative affect levels had already peaked days before the exam. No such differential effects were seen overall at recovery or in regards to positive emotions. Our results indicate the importance of addressing stress and emotion trajectories in prevention and intervention programs targeting depression in college students.
