In the cerebral cortex, neurons are subject to a continuous bombardment ofsynaptic inputs originating from the network's background activity. This leadsto ongoing, mostly subthreshold membrane dynamics that depends on thestatistics of the background activity and of the synapses made on a neuron.Subthreshold membrane polarization is, in turn, a potent modulator of neuralresponses. The present paper analyzes the subthreshold dynamics of the neuralmembrane potential driven by synaptic inputs of stationary statistics. Synapticinputs are considered in linear interaction. The analysis identifies regimes ofinput statistics which give rise to stationary, fluctuating, oscillatory, andunstable dynamics. In particular, I show that (i) mere noise inputs can drivethe membrane potential into sustained, quasiperiodic oscillations (noise-drivenoscillations), in the absence of a stimulus-derived, intraneural, or networkpacemaker; (ii) adding hyperpolarizing to depolarizing synaptic input canincrease neural activity (hyperpolarization-induced activity), in the absenceof hyperpolarization-activated currents.Comment: 16 pages, 7 figure
