From: Modulation of sympathetic preganglionic neuron activity via adrenergic receptors
Responses of EPSP-SPNs to NE and Dxm. a EPSP-SPNs were gradually depolarized from 3 to 5 min after the commencement of the superfusion with 1 μM NE. The responses recovered in about 10 min after washout. Dxm brought about no change of the membrane potential. To compare input resistances and EPSPs at the same membrane potential, the membrane potential of the neuron was adjusted to the same level as that of control by negative current injection at b-2. b-1 EPSPs in a faster sweep representation at control. b-2 Increase of EPSPs by NE. The application of NE increased the frequency and augmented the voltage of the EPSPs. b-3 Attenuation of EPSPs by Dxm. Dxm decreased both the frequency and voltage of the EPSPs
