Measure name | Abbreviated label used in figures | Formal definition |
---|---|---|
Network spike rate | Not applicable | Total number of spike events occurring on all channels within a 4Â ms bin. |
Network spike profile | Not applicable | Network spike rate vs time during global burst events. T0 is defined by the time at which the bin containing the maximum rate occurred and is based on the Simmux algorithm [17]. |
Spikes per channel during global bursts | C-spikes | Number of spike events per channel during a global burst event. |
Spikes on all channels during global bursts | G-spikes | The sum of spike events occurring on all channels during a global burst event. |
Active channels during global bursts | C-active | Number of channels showing spiking activity during a global burst event when single channel burst criteria are met; see Methods. |
Burst duration (channel) | C-duration | Time between first and last spike events on a channel during a global burst event. |
Burst duration (global) | G-duration | Time between first and last spike events on all participating channels during a global burst event. |
In-burst ISI | ISI-burst | Mean interspike interval derived from all events occurring on all channels during a global burst event. |
Overall ISI | ISI-all | Mean interspike interval derived from all events occurring on all channels during a given recording. |
Proportion of spikes occurring in bursts | SIB | ‘Spikes in bursts’: spike events occurring within global burst events as a proportion of the total number of spike events occurring during a recording. |
Inter-burst interval | IBI | ‘Inter-burst interval’: time between the last spike of a preceding burst event and the first spike of the next burst event. |
