Intrinsic determinants of firing pattern in Purkinje cells of the turtle cerebellum in vitro.
Jørn Hounsgaard,Jens Midtgaard +1 more
TL;DR: It is concluded that turtle Purkinje cells display the basic firing properties and underlying conductances known from Purkinjen cells of other vertebrates and it is suggested that spiny dendrites rather than branch points are ‘hot spots’.

Multiple Modes of Action Potential Initiation and Propagation in Mitral Cell Primary Dendrite
TL;DR: The balance of spatially distributed excitatory and inhibitory inputs can dynamically switch the mitral cell firing among four different modes: axo-somatic initiation with back-propagation, dendritic initiation either with no forward propagation, forward propagation alone, or forward propagation followed by back- Propagation.

Computational Analysis of Action Potential Initiation in Mitral Cell Soma and Dendrites Based on Dual Patch Recordings
TL;DR: The combination of loading effects and much higher sodium channel density in the axon relative to the soma-dendritic region results in significantly lower "voltage threshold" for action potential initiation in the Axon; theAxon therefore fires first unless the voltage gradient in the primary dendrite is steep enough for it to reach its higher threshold.

Stellate cell inhibition of Purkinje cells in the turtle cerebellum in vitro.
TL;DR: It is suggested that Ca2+ spike‐mediated reduction in Purkinje cell excitability may be prevented by the stellate cell IPSP‐ mediated reduction inCa2+ influx.

Spatial distribution of Ca2+ influx in turtle Purkinje cell dendrites in vitro: role of a transient outward current.
TL;DR: The results suggest that the intrinsic potassium conductances dynamically modulate spatial integration and influence the compartmentalization of Ca2+ spikes and [Ca2+]i changes in the dendrites.
