Different evidence suggests that the endocannabinoid system plays an important role in the regulation of emotional-like behaviour. Thus, the CBi cannabinoid receptor is widely distributed in limbic and cortical areas involved in the control of emotion. The administration of cannabinoid ligands produces emotional-like responses in different behavioural paradigms. Furthermore, cannabinoids also exert a modulatory role on the activity of the hypothalamic-pituitary adrenal axis (HPA), and these compounds modulate the release of several neurotransmitters involved in emotional behaviour, including CCK and GABA,... 

Atonia Jouvet s great discovery, the abolition of muscle tone associated with REM sleep, is represented in my dream cataplexy. Like narcoleptics in real life, strong emotion - especially surprise - produces atonia. Perhaps I now recognize Jouvet s achievement in my behaviour. 

Emotions can have a considerable effect on eating behaviour. Many people do not feel like eating if they are worried or depressed, while, conversely, others turn to food for solace when they feel miserable - comfort eating . (See chapters on obesity and binge eating for further discussion of this issue.)... 

There is still a long way to go before some of these issues are unravelled, especially as measuring a person s emotional state is one of the most vexing problems in affective science (Mauss and Robinson, 2009). However, it is clear that understanding the relationship between emotions and liking will provide industry with a much better understanding of consumer choice behaviour. 

An important function of culture is related to the reduction of uncertainty (Van Hoewijk 1988) or even anxiety (Schein 2004) which, consequently, leads to more continuity, because less time is spent on various mutual adjustments within a group. The fact that people know what to expect in a variety of situations - e.g. with regard to particular rituals (like celebrations, meetings, appointments and so on), the expression of emotions, dress codes, behaviours, et cetera - makes life more predictable and hence more fluent. Cultme has also been linked to adaptation (Schein 1992) and habituation. Habituation is well-developed in all organisms that have a nervous system - the working of this mechanism has been described in as primitive a life form as the marine snail (Kandel and Schwartz 1985 817 ff.). Adaptation is important for learning, for continuity and therefore for survival.
