The impact of spike timing variability on the signal-encoding performance of neural spiking models [PDF]
, 2002 It remains unclear whether the variability of neuronal spike trains in vivo arises due to biological noise sources or represents highly precise encoding of temporally varying synaptic input signals. Determining the variability of spike timing can provide

Voltage- and Branch-Specific Climbing Fiber Responses in Purkinje Cells
Cell Reports, 2018 Summary: Climbing fibers (CFs) provide instructive signals driving cerebellar learning, but mechanisms causing the variable CF responses in Purkinje cells (PCs) are not fully understood.

Voltage-stepping schemes for the simulation of spiking neural networks [PDF]
Journal of Computational Neuroscience, 2008 The numerical simulation of spiking neural networks requires particular attention. On the one hand, time-stepping methods are generic but they are prone to numerical errors and need specific treatments to deal with the discontinuities of integrate-and-fire models.

Physiological synaptic signals initiate sequential spikes at soma of cortical pyramidal neurons
Molecular Brain, 2011 The neurons in the brain produce sequential spikes as the digital codes whose various patterns manage well-organized cognitions and behaviors. A source for the physiologically integrated synaptic signals to initiate digital spikes remains unknown, which ...

Characterization of voltage-gated Ca(2+) conductances in layer 5 neocortical pyramidal neurons from rats. [PDF]
PLoS ONE, 2009 Neuronal voltage-gated Ca(2+) channels are involved in electrical signalling and in converting these signals into cytoplasmic calcium changes. One important function of voltage-gated Ca(2+) channels is generating regenerative dendritic Ca(2+) spikes ...
