This research investigated impulse buying as resulting from the depletion of a common—but limited—resource that governs self-control. In three investigations, participants' self-regulatory resources were depleted or not; later, impulsive spending responses were measured. Participants whose resources were depleted, relative to participants whose resources(More)
Impaired wakefulness in machine operators poses a danger not only to themselves but often also to the public at large. While on duty, such persons are expected to be continuously, i.e., without interruption, on the alert. For that purpose, we designed and carried out an experimental model of continuous vigilance monitoring using electroencephalography (EEG)(More)
The brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family and involved in nerve growth and survival. It has also become a major research focus in the investigation of both cognitive and affective processes in the human brain in the last years. Especially, a single nucleotide polymorphism on the BDNF gene called BDNF Val66Met gained(More)
The authors and the Pew Center would like to thank the many reviewers for their time and expertise. The authors would also like to acknowledge the support provided by the Pew Center, particularly Steve Seidel's insightful contribution to the policy discussion and the valuable advice and guidance provided by Sanjana Ahmad and Judi Greenwald.

The authors deal with sleep changes in patients after brain injury. Ten patients were examined with the use of daytime routine EEG and night polysomnography. The amount of REM sleep is most sensitive to brain damage and is reduced in all patients with nonspecific epileptiform changes in the EEG. Changes in deep synchronous sleep are less frequent and are(More)
The main bulk of the larval tail in Xenopus laevis is composed of thick muscle fibres which are succinate dehydrogenase (SDH) negative and show strong positive ATPase activity only at alkaline preincubation (pH 10.4). The thin muscle fibres (which cover the surface of the myotomes and extend to the tail tip) show positive SDH activity as well as strong(More)
Relationship between amplitude and interval of healthy and epileptic children's alpha activity was investigated. A directly proportional, though non-linear (mostly exponential) correlation was found, i. e. the higher the waves, the wider their are, and vice versa, the lower, the narrower. This is a well-known feature of clinical electroencephalography,(More)
