Analysis of pacemaker activity in a two-component model of some brainstem neurons
Henry C. Tuckwell, Ying Zhou, Nicholas J. Penington
Serotonergic, noradrenergic and dopaminergic brainstem (including midbrain) neurons, often exhibit spontaneous and fairly regular spiking with frequencies of order a few Hz, though…
Simplified models of pacemaker spiking in raphe and locus coeruleus neurons
Henry C. Tuckwell, Ying Zhou, Nicholas J. Penington
Many central neurons, and in particular certain brainstem aminergic neurons exhibit spontaneous and fairly regular spiking with frequencies of order a few Hz. A large number of ion…
Computational modeling of spike generation in serotonergic neurons of the dorsal raphe nucleu
Henry C. Tuckwell, Nicholas J. Penington
We consider here a single-compartment model of these neurons which is capable of describing many of the known features of spike generation, particularly the slow rhythmic pacemakin…
Properties of IA in a serotonergic neuron of the dorsal raphe nucleus
Nicholas J Penington, Henry C Tuckwell
Voltage clamp data were analyzed in order to characterize the properties of the fast potassium transient current IA for a serotonergic neuron of the rat dorsal raphe nucleus (DRN).…
