Long-range neural synchrony in behavior

Annu Rev Neurosci. 2015 Jul 8;38:171-94. doi: 10.1146/annurev-neuro-071714-034111. Epub 2015 Apr 6.

Abstract

Long-range synchrony between distant brain regions accompanies multiple forms of behavior. This review compares and contrasts the methods by which long-range synchrony is evaluated in both humans and model animals. Three examples of behaviorally relevant long-range synchrony are discussed in detail: gamma-frequency synchrony during visual perception, hippocampal-prefrontal synchrony during working memory, and prefrontal-amygdala synchrony during anxiety. Implications for circuit mechanism, translation, and clinical relevance are discussed.

Keywords: coherence; gamma; hippocampus; oscillations; prefrontal cortex; theta.
