“…The increased activity observed in precuneus during focal PM trials supports the idea that the episodic retrieval processes engaged during these trials may be spontaneous, that is, occurring in the absence of sustained aPFC activation (see also Beck, Ruge, Walser, & Goschke, 2012). Although we do not have a strong interpretation regarding the connectivity pattern observed between right middle temporal gyrus and aPFC during focal PM, we speculate that it may reflect a bottom-up retrieval process initiated by the temporal cortex, that may enable the suspension of on-going processing, shifting focus towards the retrieval-related significance of the cue.…”

Identifying the processes by which people remember to execute an intention at an appropriate moment (prospective memory) remains a fundamental theoretical challenge. One account is that top-down attentional control is required to maintain activation of the intention, self-initiate intention retrieval, or support monitoring. A diverging account suggests bottom-up spontaneous retrieval can be triggered by cues that have been associated with the intention; sustained attentional processes are not required. We used a specialized experimental design and fMRI methods to selectively marshal and identify each process. Results revealed a clear dissociation. One prospective memory task recruited sustained activity in attentional control areas, such as anterior prefrontal cortex; the other engaged purely transient activity in parietal and ventral brain regions associated with attentional capture, target detection, and episodic retrieval. These patterns provide critical evidence that there are two neural routes to prospective memory, with each route emerging under different circumstances.

“…These findings complement and extend prior work that has leveraged fMRI data to dissociate PM strategies using activity from a distributed network of brain regions. For example, work by McDaniel et al (McDaniel et al, 2013) showed that activity in frontoparietal control networks was greater in conditions that require greater levels of strategic monitoring (e.g., non-focal vs. focal PM targets; for other relevant data, see Reynolds et al, 2009; Burgess et al, 2011; McDaniel et al, 2013; Barban et al, 2014; Beck et al, 2014). …”

“…Theories of PM (Cohen and O’Reilly, 1996; Gollwitzer and Brandstätter, 1997; McDaniel and Einstein, 2000) posit that two strategies can be used: Participants can use working memory (WM) to actively monitor the environment for an appropriate time or event (Koechlin and Hyafil, 2007; Gilbert, 2011) or they can store the intention in episodic memory (EM) and hope that it is automatically retrieved when the time comes to act on that intention (McDaniel and Einstein, 2007b; Beck et al, 2014; for related ideas about dual systems involved in PM and control see Cohen and O’Reilly, 1996 and Braver, 2012). PM is typically studied using a dual-task paradigm in which a PM task is embedded in another cognitive task that requires vigilance and frequent behavioral decisions (the “ongoing task”).…”

Neural evidence of the strategic choice between working memory and episodic memory in prospective remembering

Theories of prospective memory (PM) posit that it can be subserved either by working memory (WM) or episodic memory (EM). Testing and refining these multiprocess theories of PM requires a way of tracking participants’ reliance on WM versus EM. Here we use multi-voxel pattern analysis (MVPA) to derive a trial-by-trial measure of WM use in prospective memory. We manipulated strategy demands by varying the degree of proactive interference (which impairs EM) and the memory load required to perform the secondary task (which impairs WM). For the condition in which participants were pushed to rely more on WM, our MVPA measures showed 1) greater WM use and 2) a trial-by-trial correlation between WM use and PM behavior. Finally, we also showed that MVPA measures of WM use are not redundant with other behavioral measures: in the condition in which participants were pushed more to rely on WM, using neural and behavioral measures together led to better prediction of PM accuracy than either measure on its own.

“…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.…”

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.
