The role of phase synchronization in memory processes. Fell, J. & Axmacher, N. Nature Reviews Neuroscience, 12(2):105–118, February, 2011. Publisher: Nature Publishing Group![The role of phase synchronization in memory processes [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex The term 'phase' denotes the angle corresponding to the momentary deflection of an oscillation. Phase synchronization of neural oscillations refers to the correlation of phase values between two brain regions.Electroencephalography and local field potential oscillations reflect fluctuations in neuronal membrane potential and are thus related to changes in neural excitability and to spike timing. Therefore, phase synchronization between two brain regions reflects correlations of neural excitability and spike timing.Correlated changes in neural excitability and spike timing are the basis for two major functions of phase synchronization: neural communication and spike timing-dependent plasticity. It is still an open question, however, how these functions interact with each other.Increased phase synchronization has been observed during various memory processes, including working memory maintenance and long-term memory encoding and retrieval. Neural plasticity is probably most relevant for long-term memory formation, whereas neural communication is likely to play a part during both working and long-term memory processes.Recent studies suggest that working and long-term memory operations, which have long been considered separately, are supported by overlapping brain regions, particularly the hippocampus. Phase synchronization could constitute a common neural signature of both working memory maintenance and long-term memory formation.Computer models propose that cross-frequency coupling of the amplitude (and possibly even phases) of gamma oscillations to phases of theta oscillations supports the representation of multiple items in working memory. Indeed, modulations of cross-frequency phase–phase and phase–amplitude coupling have been observed depending on working memory operations.Further data indicate that cross-frequency phase–amplitude and phase–phase coupling may also support long-term memory encoding of sequences and cued recall of spatial positions. Cross-frequency phase–phase and phase–amplitude coupling may constitute mechanisms that support the exchange of object representations between working and long-term memory.Taken together, both empirical and theoretical evidence suggests that phase synchronization and complementary phase-based mechanisms provide a common 'neural protocol' for various memory-related operations.
