ABSTRACT
The contributions of neuroscientists to the explanatory discourses about peak-experiences offer many narratives that revolve around the notion of 'shock'. They note the changes in attention that follow the shock; the 'daze' that can be observed; the narrowing of consciousness and of concentration, the detachment, the depersonalization, the disorientation. The corresponding physiological symptoms of the central nervous system are readily produced. Mention might be made of an 'adrenalin rush' or the role of epinephrine, the hormone and neurotransmitter, the palpitations and tremors that could be involved. Almost always, there is the reference to the autonomic and central nervous systems, the electrical activity of the brain, blood pressure, heart rate, muscle responses and other signs. This is but a small recognition of the multiple contributions of the scientific community. Emotion is central to tourism, the thrills of anticipation and of daydreaming, the accumulation of travel accounts and advice, the excitement and dread of departure, the disappointment of having to return.
