spike_times(trace,t​hreshold1)

This function detects and locates the time points of action potentials in a trace of membrane potential as a function of time in a neuron. The trace should represent a current clamp recording from a neuron.
Input:
"trace" is the membrane voltage array of the neuron "threshold" is the factor times the maximum membrane potential (peak of spike) This "threshold" is the value for which the action potentials have to cross to be detected.

Output:
The output array is the index location of spikes.
