In cowpea (Vigna unguiculata), fall armyworm (Spodoptera frugiperda) herbivory and oral secretions (OS) elicit phytohormone production and volatile emission due to inceptin [Vu-In; ICDINGVCVDA], a peptide derived from chloroplastic ATP synthase g-subunit (cATPC) proteins. Elicitor-induced plant volatiles can function as attractants for natural enemies of insect herbivores. We hypothesized that ...

Recent neuropsychological and neuroscientific research suggests that people who experience more déjà vu display characteristic patterns in normal recognition memory. We conducted a large individual differences study (n = 206) to test these predictions using recollection and familiarity parameters recovered from a standard memory task. Participants reported déjà vu frequency and a number of its ...

Normal patterns of déjà experience in a healthy, blind male: Challenging optical pathway delay theory. Abstract We report the case of a 34 year-old healthy, blind male, MT, who experiences normal patterns of déjà vu. The optical pathway delay theory of déjà vu formation assumes that neuronal input from the optical pathways is necessary for the formation of the experience. Surprisingly, although...

With regard to both psychological and physiological processes, ambulatory measurement is 'worth the trouble' because it provides higher ecological validity and higher predictive validity for clinical outcomes than laboratory studies. This observation has led to the development of the VU University Ambulatory Monitoring System (VU-AMS) that specifically focuses on ambulatory assessment of activi...

For over a century, the phenomenon of déjà vu has attracted much interest, and in recent times, it has been studied by researchers in various scientifi c fi elds (e.g., Brown, 2003, 2004; Sno & Linszen, 1990). Empirical studies of déjà vu phenomena have used interviews and questionnaires with normal people as well as psychiatric patients (e.g., Neppe, 1983; Sno & Linszen, 1990; Sno, Schalken, d...

French expression standing for the phrase "already seen" is a déjà vu. It is thought that as much as 97% of the population have experienced déjà vu at least once in their lifetime and 67% experience it regularly. The explanations of this phenomenon in novels and poems include reincarnation, dreams, organic factors, and unconscious memories. In this narrative review connection between déjà vu an...

Déjà vu is a nebulous memory experience defined by a clash between evaluations of familiarity and novelty for the same stimulus. We sought to generate it in the laboratory by pairing a DRM recognition task, which generates erroneous familiarity for critical words, with a monitoring task by which participants realise that some of these erroneously familiar words are in fact novel. We tested 30 p...
