The aim of this experimental study was to clarify whether affective states with different arousal and valence levels influence the perceived funniness and aversiveness shown as a response to humor stimuli. We used the ...

Wakefulness is one of the daily recurring states of arousal, during which neuralnetworks actively acquire external information, continuously sense and logicallyprocess them, and continuously control voluntary movements. ...

The objective of the present study was to further elucidate the mechanisms involved in the wake-promoting effects of psychomotor-stimulants. Many previous studies have tightly linked the effects of stimulants to dopamine ...

The classification of user's emotions based on their behavioral characteristic, namely their keyboard typing and mouse usage pattern is an effective and non-invasive way of gathering user's data without imposing any ...

Previous research has shown opposite effects of dual tasking on the vigilance decrement phenomenon. We examined the executive (i.e., detecting infrequent critical signals) and arousal (i.e., sustaining a fast reaction to ...

Appetitive behaviours occur in a state of behavioural and physiological activation that allows the optimal performance of these goal-directed behaviours. Here, we tested the hypothesis that histamine neurons under the ...

The histaminergic system is one component of the ascending arousal system which is involved in wakefulness, neuroendocrine control, cognition, psychiatric disorders and motivation. During the appetitive phase of motivated ...

During physical efforts and sport practice, vigilance is responsible for maintaining an optimal state of activation, guaranteeing the ability to quickly respond and detect unexpected, but critical, stimuli over time. ...

Central chemoreception, the detection of CO(2)/H(+) within the brain and the resultant effect on ventilation, was initially localized at two areas on the ventrolateral medulla, one rostral (rVLM-Mitchell`s) the other caudal ...
