Fig 11. OB gamma oscillations are robust to strongly increased, but not reduced, MC→GC synaptic weights.
A: Voltage timeseries of representative GCs (top) and GC-mediated GABAA synaptic conductances on MCs (bottom), under control conditions and following a 50% reduction of MC→GC synaptic weights (50%WMC-GC). B: Membrane potential timeseries of two pairs of MCs with 50%WMC-GC. C: Simulated LFP (top) during odor presentation, with autocorrelation (middle) and frequency power spectrum (bottom), with 50%WMC-GC. D: As in A, but under control conditions compared with an eightfold increase in the MC→GC synaptic weight (800%WMC-GC). E: As in B, but with 800%WMC-GC. F: As in C, but with 800%WMC-GC.
