Hippocampus ripple

Webb19 apr. 2016 · The hippocampus generates sharp wave-ripple complexes (SWR), in which a strong excitatory input from CA3 pyramidal cells leads to broadly distributed postsynaptic potentials (the sharp waves) in CA1 stratum radiatum, while the pyramidal layer shows a quick bout of high frequency LFP activity (the ripple) [ 9 – 11 ].

These empirical studies suggest that the hippocampal SWRs and spindle-ripples represent distinct phenomena, especially with respect to their interactions with the cortex, and would need to be modeled separately.
