(A) Diagram showing the location of recorded cells. (B) Exemplary images of RhebCA-expressing cells with a neuronal morphology in the RMSelbow and at the base of the olfactory bulb (OBbase). (C–F) Left: current-induced action potentials, middle: spontaneous synaptic currents and right: higher temporal resolution for synaptic currents recorded in ectopic RhebCA cells at the locations indicated on the left. Axis (action potentials): x: 50 msec, y: 20 mV (synaptic currents): x: 2 sec, y: 20 pA; (synaptic currents, higher resolution): x: 100 msec, y: 10 pA. Scale bar: 50 μm.
