“…Proskovec et al (2018) in a MEG study localized theta in the left dorsolateral prefrontal cortex and reported an increase, but their figure 3 shows the opposite pattern: after a short transient increase, theta decreased below baseline level and maintained in this state until probe presentation. Contrary to the results by Proskovec, theta continuously increased during delay period in two EEG studies in exactly the same paradigm (Berger et al, 2019;Eschmann et al, 2018). The spatial WM task employed by these three studies was first published in EEG study by Griesmayr et al (2014) 1 , which also reported a theta increase.…”

“…Several works have shown that memory encoding and retrieval is supported by an increased synchronization of slow oscillatory activity (3-8 Hz), notably in the medial temporal lobe (Heusser, Poeppel, Ezzyat, & Davachi, 2016;Clouter, Shapiro, & Hanslmayr, 2017;Burke et al, 2014;. Alternatively, an increase of such activity in the frontal medial electrodes is also a strong correlate of the higher recruitment of cognitive control mechanisms (Cavanagh & Frank, 2014;Mückschel, Dippel, & Beste, 2017;Eschmann, Bader, & Mecklinger, 2018), that may also occur during the TNT procedure. The decrease we report here between 5 and 9 Hz might indeed reflect a mixed process of both higher neocortical inhibitory engagement and a decrease of memory replay.…”

Does the heart forget? Modulation of cardiac activity induced by inhibitory control over emotional memories

The subjective construction surrounding the perception of negative experiences is partly built upon bodily afferent information, comprising heart, gut or respiratory signals. While this bottom-up influence has been extensively described, the opposite pathway, the putative influence of cognitive processes over autonomic response, is still debatable. Emotion regulation and the ability to control maladjusted physiological response associated with thoughts and memories is a recurrent concern for most psychiatric disorders and mental health as a whole. Memory suppression (i.e. exerting inhibitory control toward unwanted memories) has been proposed as a possible solution to perform such regulation. This method, however, also holds debates as it could putatively worsen distressing reactions when unsuccessful, or simply be ineffective on the physiological roots of emotions. Here, we tested the hypothesis that memory suppression can influence the physiological marker of emotions in two studies using the "Think/No-Think" paradigm. We measured in healthy participants the aftereffect of suppressing negative memories on their cardiac reaction toward the excluded memories. Results of Study 1 revealed that an efficient control of memories was associated with a long-term inhibition of the cardiac deceleration normally induced by disgusting stimuli. Attempts to suppressing sad memories, on the opposite, aggravated cardiac response, an effect that was largely related to the inability to forget this specific material. Study 2 recorded concurrent electroencephalographic (EEG) response during the TNT task to track the oscillatory dynamics supporting the inhibitory control of memories and estimate their role in the inhibition of the later cardiac response. We found that the decrease of the 5-9 Hz frequency band, a prominent electrophysiological marker of memory suppression, was indeed related to the subsequent inhibition of the cardiac response toward disgusting stimuli. These results show that the modulation of cognitive representations can have long-term effects on the cardiac system. They further support the notion that cognitive control over unwanted emotional memories, when successful, can reduce the autonomic aversive processes to achieve emotional regulation. Our findings open new avenues for possible interventions focused on training this suppression mechanism to reduce the impact of distressing intrusive memories on mental health.

“…Prior research has indicated that oscillations at theta frequencies (3-7 Hz in humans) are involved in navigation and spatial memory (Eschmann, Bader, & Mecklinger, 2018;Bohbot, Copara, Gotman, & Ekstrom, 2017;Hasselmo, Hinman, Dannenberg, & Stern, 2017;Namboodiri, Levy, Mihalas, Sims, & Hussain Shuler, 2016;Chakravarthy & Balasubramani, 2015;Hartley, Lever, Burgess, & O'Keefe, Figure 6. Distinct timefrequency markers for processing different types of shortcuts.…”

Central to the concept of the “cognitive map” is that it confers behavioral flexibility, allowing animals to take efficient detours, exploit shortcuts, and avoid alluring, but unhelpful, paths. The neural underpinnings of such naturalistic and flexible behavior remain unclear. In two neuroimaging experiments, we tested human participants on their ability to navigate to a set of goal locations in a virtual desert island riven by lava, which occasionally spread to block selected paths (necessitating detours) or receded to open new paths (affording real shortcuts or false shortcuts to be avoided). Detours activated a network of frontal regions compared with shortcuts. Activity in the right dorsolateral PFC specifically increased when participants encountered tempting false shortcuts that led along suboptimal paths that needed to be differentiated from real shortcuts. We also report modulation in event-related fields and theta power in these situations, providing insight to the temporal evolution of response to encountering detours and shortcuts. These results help inform current models as to how the brain supports navigation and planning in dynamic environments.
