New science: Our preprint on #LocalFieldPotentials (#lfp) and E/I balance just dropped on #bioRxiv
We took direct measurements of excitatory and inhibitory firing (using large simultaneously-recorded neural ensembles allowing us to actually identify excitatory and inhibitory neurons!) and compared it to measurable features from local field potentials in four remarkable data sets (1 from rat mPFC, 1 from rat OFC, 1 from mouse hippocampus, and 1 from mouse VI).
We find that while 1/f slope and gamma oscillations showed region and context dependencies, broadband (6-80 Hz) and high gamma (80-150 Hz) power consistently correlated with E/I activity ratios, supporting their use as proxy measures.
