STEP_time_to_first_spike

biophysics_fitting.ephys.STEP_time_to_first_spike(t, v, stim_onset, thresh=None)

Computes the time to first spike (TTFS) of a voltage trace for a step stimulus.

Note

The time to a spike is taken to be the time until the peak of the spike, not e.g. the peak of the second derivative.

Parameters:
t : numpy.ndarray

Array of time values.

v : numpy.ndarray

Array of voltage values.

thresh : float, optional

Voltage threshold for spike detection. Defaults to None.

Returns:

Time to first spike.

Return type:

float
