Interneuronal gap junctions increase synchrony and robustness of hippocampal ripple oscillations

Sharp wave–ripples ( SWR s) are important for memory consolidation. Their signature in the hippocampal extracellular field potential can be decomposed into a ≈100 ms long sharp wave superimposed by ≈200 Hz ripple oscillations. How ripple oscillations are generated is currently not well understood. A promising model for the genesis of ripple oscillations is based on recurrent interneuronal networks ( INT ‐ INT ). According to this hypothesis, the...
