Sleep disorders
(1) An abrupt change from a deep stage of NREM sleep to a lighter stage, or from REMS to awake, with the possibility of awakening as the final outcome. Arousal may be accompanied by increased tonic EMG activity and heart rate, as well as body movements.
(2) The interruption of sleep by continuous alpha activity and increased EMG activity of > 3 seconds.

Autonomic arousal, a property of the brain that is strongly preserved across different species, is a robust indicator of an altered developmental trajectory, Fagiolini and Artoni found.
However, in every condition, strangers quickly went "in sync" and did so in each branch of the autonomic nervous system whether they were high or low in arousal. Whether the social or physiological context of synchrony contributed to social outcomes, however, depended on which branch of the autonomic nervous system displayed synchrony.
According to Laan and Both (2008), and consistent with the predictions of the IMM, sexual arousal and desire are responses to relevant stimuli, regardless of whether one is aware of the stimuli.
The study consisted of two experimental conditions, high and low arousal, and one control condition (see Figure 1).
To examine the effects of the different arousal states on signaldetection measures, independent-measure analyses of variance (ANOVAs) were applied on estimates of sensitivity d and response bias c (see Table 1) with arousal state (control, violence, erotica) as the between-subject variable.
Each participant viewed one set of the 135 words (fifteen words for each valence and arousal combination).
Zestra is a patented blend of natural oils clinically-proven in double-blind placebo-controlled clinical trials in 276 women to increase in a statistical significant manner the arousal, desire and sexual satisfaction in FSI/AD women.
This circumlex model, which interchangeably known also as Affective Space Model (ASM), suggested that emotions are represented by two-dimensional space, based on arousal and valence axes.

Emotional arousal induces a sweat reaction, which is particularly prevalent at the surface of the hands and fingers and the soles of the feet.
However, it is thought that one of the major problems with the inverted-U hypothesis as an explanation for the relationship between arousal and performance is the way in which activation and arousal are operationalised (Sapolsky, 2015).
