“…PFC is the cortical structure most extensively studied in the context of hippocampo-cortical communication (Maingret et al, 2016;Peyrache et al, 2009;Peyrache, Battaglia, & Destexhe, 2011;Siapas and Wilson, 1998;Wierzynski et al, 2009), due to monosynaptic and highly plastic inputs from ventral hippocampus (Laroche, Davis, & Jay, 2000;Swanson et al, 1981), and the hypothesized cooperation with hippocampus on various memory tasks (Doyere et al, 1993;Jones & Wilson, 2005). The extensive connectivity of PFC with hippocampus and the range of cortical/subcortical structures (Fuster, 1988), as well as the selective activation of PFC during remote, but not recent memory retrieval (Maviel, Durkin, Menzaghi, & Bontempi, 2004), suggest that the PFC might gradually take over the hub position in the organization of remote memories, as they are progressively integrated with cortical schemas (Frankland & Bontempi, 2005;Tse et al, 2007;Holleman & Battaglia, 2015). Simultaneous hippocampal-PFC recordings, which typically included infra/prelimbic parts of medial prefrontal cortex (mPFC), have shown asymmetric SWR-triggered population activity peri-event time histograms (PETH), with increases from baseline up to 200 ms prior to SWR that persisted for 1-2 s following SWR (Peyrache et al, 2009;Siapas & Wilson, 1998;Wierzynski et al, 2009).…”

Memory consolidation is a gradual process through which episodic memories become incorporated into long-term 'semantic' representations. It likely involves reactivation of neural activity encoding the recent experience during non-REM sleep. A critical prerequisite for memory consolidation is precise coordination of reactivation events between the hippocampus and cortical/subcortical structures, facilitated by the coupling of local field potential (LFP) oscillations (slow oscillations, sleep spindles and sharp wave/ripples) between these structures. We review the rapidly expanding literature on the qualitative and quantitative aspects of hippocampal oscillatory and neuronal coupling with cortical/subcortical structures in the context of memory reactivation. Reactivation in the hippocampus and cortical/subcortical structures is tightly coupled with sharp wave/ripples. Hippocampal-cortical/subcortical coupling is rich in dimensionality and this dimensionality is likely underestimated due to the limitations of the current methodology.

“…On the other hand, it is highly plausible that task performance leaves a neural trace which manifests as altered propagation of intrinsic activity. In fact, such traces must underlie episodic memory and skill acquisition (Albert et al 2009;Holleman and Battaglia 2015).…”

The behaviors that define autism spectrum disorders (ASDs) have been hypothesized to result from disordered communication within brain networks. Several groups have investigated this question using resting-state functional magnetic resonance imaging (RS-fMRI). However, the published findings to date have been inconsistent across laboratories. Prior RS-fMRI studies of ASD have employed conventional analysis techniques based on the assumption that intrinsic brain activity is exactly synchronous over widely separated parts of the brain. By relaxing the assumption of synchronicity and focusing, instead, on lags between time series, we have recently demonstrated highly reproducible patterns of temporally lagged activity in normal human adults. We refer to this analysis technique as resting-state lag analysis (RS-LA). Here, we report RS-LA as well as conventional analyses of RS-fMRI in adults with ASD and demographically matched controls. RS-LA analyses demonstrated significant group differences in rs-fMRI lag structure in frontopolar cortex, occipital cortex, and putamen. Moreover, the degree of abnormality in individuals was highly correlated with behavioral measures relevant to the diagnosis of ASD. In this sample, no significant group differences were observed using conventional RS-fMRI analysis techniques. Our results suggest that altered propagation of intrinsic activity may contribute to abnormal brain function in ASD.
