Network modulation in theta/gamma rhythms is not substantially affected by interneuronal geometry. A. Three network structures including O and B cells with horizontal dendrites (control, left), vertically imbalanced O cells (O-vert, middle) and vertically imbalanced B cells (B-vert, right). B. Similar effects of negative electric field on control, O-vert and B-vert OPb networks (top to bottom: instantaneous frequency plots, rasters). C. Similar effects of positive electric field on control, O-vert and B-vert OPb networks (top to bottom: instantaneous frequency plots, rasters).
