“…For example, disrupting this region 1) selectively impaired verbal learning but did not affect encoding of face stimuli (Skrdlantová et al, 2005) or abstract stimuli (Epstein, Sekino, Yamaguchi, Kamiya, & Ueno, 2002) and 2) selectively impaired deep processing of words while memory for items encoded in the shallow processing condition was unaffected (Innocenti et al, 2010).…”

A network approach for modulating memory processes via direct and indirect brain stimulation: Toward a causal approach for the neural basis of memory This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. that disrupting frontal or parietal regions also impairs memory performance, suggesting that these regions also play necessary roles in declarative memory. On the other hand, a handful of both invasive and non-invasive studies have also suggested modest improvements in memory performance following stimulation. These studies typically target brain regions connected to the hippocampus or other memory "hubs," which may affect endogenous activity in connected areas like the hippocampus, suggesting that to augment declarative memory, altering the broader endogenous memory network activity is critical. Together, studies reporting memory improvements / impairments are consistent with the idea that a network of distinct brain "hubs" may be crucial for successful memory encoding and retrieval rather than a single primary hub such as the hippocampus. Thus, it is important to consider neurostimulation from the network perspective, rather than from a purely localizationalist viewpoint. We conclude by proposing a novel approach to neurostimulation for declarative memory modulation that aims to facilitate interactions between multiple brain "nodes" underlying memory rather than considering individual brain regions in isolation.

“…Also, Rossi et al [31] in a study with pictorial information, reported that the left DLPFC is involved in encoding operations while the right DLPFC is crucial for retrieval, providing evidence for the idea that even with non-verbal material the left DLPFC is implicated in encoding while the right DLPFC is involved in the retrieval phase. Further evidence for the crucial role of the left DLPFC was provided by innocenti et al [32] who investigated the asymmetry of the DLPFC in encoding through a paradigm that differentiates between deep (semantic) and shallow (perceptual) encoding.…”

Dorsolateral prefrontal cortex, working memory and episodic memory processes: insight through transcranial magnetic stimulation techniques

The ability to recall and recognize facts we experienced in the past is based on a complex mechanism in which several cerebral regions are implicated. Neuroimaging and lesion studies agree in identifying the frontal lobe as a crucial structure for memory processes, and in particular for working memory and episodic memory and their relationships. Furthermore, with the introduction of transcranial magnetic stimulation (TMS) a new way was proposed to investigate the relationships between brain correlates, memory functions and behavior. The aim of this review is to present the main findings that have emerged from experiments which used the TMS technique for memory analysis. They mainly focused on the role of the dorsolateral prefrontal cortex in memory process. Furthermore, we present state-of-the-art evidence supporting a possible use of TMS in the clinic. Specifically we focus on the treatment of memory deficits in depression and anxiety disorders.

“…fMRI studies have consistently shown an engagement of the left VLPFC, especially when the encoding task involves semantic processing (Fletcher, Shallice & Dolan, 1998;Blumenfeld & Ranganath, 2007;Galli, 2014), whereas only few studies reported DLPFC activations (Savage et al, 2001;Blumenfeld & Ranganath, 2006). On the contrary, most TMS and tDCS studies of episodic memory found an effect of left DLPFC stimulation on subsequent retrieval (Rossi et al, 2001(Rossi et al, , 2004(Rossi et al, , 2006(Rossi et al, , 2011Epstein, Sekino, Yamaguchi, Kamiya & Ueno, 2002;Sandrini, Cappa, Rossi, Rossini & Miniussi, 2003;Skrdlantová et al, 2005;Turriziani et al, 2008;Turriziani, Smirni, Oliveri, Semenza & Cipolotti, 2010;Elmer, Burkard, Renz, Meyer & Jancke, 2009;Gagnon, Schneider, Grondin & Blanchet, 2010;Innocenti et al, 2010;Javadi, Cheng & Walsh, 2012;Javadi & Cheng, 2013;Manenti, Brambilla, Petesi, Ferrari & Cotelli, 2013) whereas only a few targeted the left VLPFC (Floel et al, 2004;Köhler et al, 2004;Kahn et al, 2005;Machizawa et al, 2010;Blumenfeld et al, 2014;Vidal-Pinero et al, 2014). A further complication in integrating fMRI and non-invasive brain stimulation findings is that most TMS and tDCS studies targeted the DLPFC by delivering the stimulation over F3 of the International 10-20 EEG system, which is more dorsal than the maximum DLPFC peak of activation reported in fMRI studies (Blumenfeld et al, 2014).…”

“…Stimuli were 368 Italian words, ranging in length between four and ten letters, which have previously been used in similar experiments in our lab (Innocenti et al, 2010;Cioncoloni et al, 2014). Four stimulus lists of 88 words each were constructed from this pool.…”

Highlights We investigated encoding-related post-stimulus brain activity in the prefrontal cortex with repetitive Transcranial Magnetic Stimulation (r-TMS)  We delivered r-TMS during encoding while a word appeared on the screen, and at different points in time after its offset  r-TMS over the ventrolateral prefrontal cortex shortly after stimulus offset decreased subsequent memory accuracy  No effects were found when r-TMS was delivered over the dorsolateral prefrontal cortex at any time point  The involvement of the ventrolateral prefrontal cortex may reflect offset-specific processes. ABSTRACTDuring encoding, the neural activity immediately before or during an event can predict whether that event will be later remembered. The contribution of brain activity immediately after an event to memory formation is however less known. Here, we used repetitive Transcranial Magnetic Stimulation (rTMS) to investigate the temporal dynamics of episodic memory encoding with a focus on post-stimulus time intervals. At encoding, rTMS was applied during the online processing of the word, at its offset, or 100, 200, 300 or 400 ms thereafter. rTMS was delivered to the left ventrolateral (VLPFC) or dorsolateral prefrontal cortex (DLPFC). VLPFC rTMS during the first few hundreds of milliseconds after word offset disrupted subsequent recognition accuracy. We did not observe effects of DLPFC rTMS at any time point. These results suggest that verbal encoding-related VLPFC engagement starts at a relatively late processing stage, and may reflect brain processes related to the offset of the stimulus.3
