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
