Memory formation crucially depends on oscillatory processes of temporally organized neural firing patterns of neuronal assemblies. In addition, coordinated interactions between low- (~ 4 Hz - 15 Hz) and high-frequency (> 30 Hz, i.e., gamma range) rhythmic neural activity have been proposed as a possible mechanism for the control and representation of mnemonic contents during wakefulness. During sleep, a fine-tuned interaction between hippocampal memory reactivations, thalamic spindle activity (13 - 15 Hz) and cortical slow oscillations (< 1 Hz) is assumed to underlie the beneficial effect of sleep on memory. A causal role of memory reactivations is supported by studies showing that inducing reactivations during sleep by cueing improves memory formation. However, the oscillatory mechanisms of “successful” memory reactivation during sleep underlying the subsequent strengthening of memory traces by reactivation are currently unknown. In this project we aim at identifying the oscillatory underpinnings of successful memory reactivations during sleep. Similar to previous studies on the “subsequent memory effect” (SME) during wakefulness, we will focus on the oscillatory correlates as well as changes in cross-frequency coupling of the “subsequent memory effect of reactivation” (SME-R) during sleep, i.e. by comparing neural signals during reactivation of subsequently remembered vs. forgotten items. In the planned experiments, we will (a) specify and characterize the oscillatory correlates of SME-R depending on different pre-reactivation microstates (up- vs. down-state of slow oscillation as inferred from surface slow waves) during several sleep macro-states (N3 vs. N2 vs. rapid-eye movement (REM) sleep) and (b) experimental induce different oscillatory patterns after the SME-R period to examine a possible causal role for SME-R related oscillatory activity (slow wave activity, spindle activity, theta activity) for later memory improvements. In addition, we will relate the SME-R during sleep to oscillatory correlates of the SME during learning as well as during retrieval testing. The results of this project will greatly enhance our theoretical understanding of the oscillatory mechanisms underlying successful memory reactivation and strengthening during sleep, and will integrate these processes with current accounts on oscillatory processes involved in memory retention during wakefulness. Furthermore, by possibly identifying that combined induction of an oscillatory pattern + reactivation improves memory consolidation during sleep, the results of this project might also have important clinical implications for patients with memory impairments and/or sleep disorders.
