Stimuli are now a mechanism to be inserted

[michaeldeistler]

Update API to insert stimuli. The new way is closer to how NEURON does it and it allows removing some boilerplate code.

Old API

stims = [nx.Stimulus(cell_ind, 0, 0.0, nx.step_current(i_delay, i_dur, i_amp, time_vec)) for cell_ind in range(num_cells)]
s = nx.integrate(network, stimuli=stims,  delta_t=dt)

New API

current = nx.step_current(i_delay, i_dur, i_amp, time_vec))
for cell_ind in range(num_cells):
    network.cell(cell_ind).branch(0).comp(0.0).stimulate(current) for cell_ind in range(num_cells)

s = nx.integrate(network, delta_t=dt)

Aside: How to deal with datasets

Previously, datasets were handled by the Stimuli class. Now, it works as follows:

for cell_ind in range(num_cells):
    network.cell(cell_ind).branch(0).comp(0.0).stimulate(nx.step_current(i_delay, i_dur, i_amp, time_vec)) for cell_ind in range(num_cells))

s = nx.integrate(network, currents=new_current_values, delta_t=dt)
