“…This contrast was chosen because it represents a major distinction made between different forms of cue in event-based prospective memory tasks and so the experimental paradigm can be kept close to a "real-life" situation 21 . While BA 10 is known to be sensitive to the processing of social versus non-social information in some situations (e.g., Gilbert et al, 2007 22 ), recent evidence suggests that haemodynamic changes in BA 10 related to prospective memory tasks are relatively insensitive to cue differences (see Burgess et al, 2011 23 for review). Thus, it is an open question whether social versus non-social cues affects BA 10 activity in the context of a prospective memory paradigm.…”

Functional Near Infrared Spectroscopy (fNIRS) is a neuroimaging technique that uses near-infrared light to monitor brain activity. Based on neurovascular coupling, fNIRS is able to measure the haemoglobin concentration changes secondary to neuronal activity. Compared to other neuroimaging techniques, fNIRS represents a good compromise in terms of spatial and temporal resolution. Moreover, it is portable, lightweight, less sensitive to motion artifacts and does not impose significant physical restraints. It is therefore appropriate to monitor a wide range of cognitive tasks (e.g., auditory, gait analysis, social interaction) and different age populations (e.g., new-borns, adults, elderly people). The recent development of fiberless fNIRS devices has opened the way to new applications in neuroscience research. This represents a unique opportunity to study functional activity during real-world tests, which can be more sensitive and accurate in assessing cognitive function and dysfunction than lab-based tests. This study explored the use of fiberless fNIRS to monitor brain activity during a real-world prospective memory task. This protocol is performed outside the lab and brain haemoglobin concentration changes are continuously measured over the prefrontal cortex while the subject walks around in order to accomplish several different tasks.

“…Studies highlighted the involvement of the rostral prefrontal cortex (RPFC), whose lateral part is activated, contrasting with the deactivation of the medial part (Burgess et al 2001;Burgess et al 2003;den Ouden et al 2005;Simons et al 2006;Rusted et al 2011;Benoit et al 2012;Barban et al 2013;Beck et al 2014; see Burgess et al 2011;Cona et al 2015 for reviews). According to the Gateway Hypothesis , the deactivation of the medial part of the RPFC and the activation of its lateral part reflect the shift of attentional focus from external stimulation (i.e.…”

“…maintenance of the intention). The involvement of other regions, such as the precuneus, the parietal lobe, the anterior and posterior cingulate cortex, the temporal cortex and the insula has been frequently reported but the role of these different regions in PM remains unclear (Burgess et al 2011).…”

Prospective memory (PM) refers to the ability to remember to execute an intention at the appropriate moment in the future, which can be performed either at the appearance of an event (event-based, EBPM) or after a certain amount of time (time-based, TBPM). PM is generally impaired during aging but the cerebral substrates of this decline have been little investigated. Using functional Magnetic Resonance Imaging (fMRI), we investigated the neural bases of PM in 20 young and 20 healthy older adults. They were proposed a task of semantic categorisation of pictures (ongoing task). For some blocks, participants only had to perform this ongoing task while, for others, a PM instruction was added. In this case, a supplementary answer in response to a specific colour of border for EBPM or at specific time intervals for TBPM was expected. PM, and more particularly TBPM, declined in older adults.For both PM conditions, older adults recruited additional brain areas, but also showed reduced deactivations of other regions. These results are discussed in light of models of the aging brain.

“…PM, however, is not a unitary process; it involves encoding and maintaining an intention and retrieving and executing it at the appropriate moment in the future. Neuroimaging studies strongly implicate the rostral prefrontal cortex (Brodmann Area [BA] 10) in PM as well fronto-parietal networks including the inferior parietal lobe (BA 40), precuneus (BA 7), and anterior cingulate (BA 32), regions activated in a wide range of tasks engaging attention, executive functions and working memory (Burgess 2011). Thus PM likely draws on attentional, executive and working memory resources; indeed, previous studies have found a positive relationship between working memory span and PM performance (Smith and Bayen 2005;Smith et al, 2011).…”

Nicotine derived from the electronic cigarette improves time-based prospective memory in abstinent smokers

Rationale: It is well-established that nicotine improves, and deprivation impairs, cognitive performance and mood in smokers. Prospective memory (PM), remembering to execute a delayed intention at a given time point, is under-explored in smokers. Whilst a handful of studies have shown improved PM with nicotine, effects of nicotine delivered via the electronic cigarette have not been investigated.Objective: This study explores whether, by comparison with placebo, nicotine delivered via the e-cigarette can improve PM, tobacco withdrawal symptoms and desire to smoke in abstinent smokers.Methods: Twenty smokers, abstinent for 8-10 hours, each completed two experimental sessions under nicotine (18mg) and placebo (0mg) e-cigarette conditions. Participants completed a single-item desire to smoke scale and the Mood and Physical Symptoms Scale (MPSS). PM was measured using the Cambridge Prospective Memory Test (CAMPROMPT).Results: Compared with placebo, the nicotine e-cigarette reduced desire to smoke and tobacco withdrawal symptoms, and improved time-based but not event-based PM. There was a moderate, marginally significant negative correlation between PM performance during abstinence and nicotine dependence.Conclusions: This is the first study to show that nicotine derived via e-cigarette can improve PM in abstinent smokers suggesting efficient nicotine delivery. That the effect of nicotine was restricted to time-based rather than event-based PM is consistent with the view that nicotine acts to improve performance on strategic (effortful) rather than automatic processing. These findings add to the growing body of evidence that the e-cigarette can replace some of the effects of nicotine derived from tobacco smoking thus highlighting its potential for smoking cessation.
