brainpy.channels.CalciumFixed#

class brainpy.channels.CalciumFixed(size, keep_size=False, E=120.0, C=0.00024, method='exp_auto', name=None, mode=None, **channels)[source]#

Fixed Calcium dynamics.

This calcium model has no dynamics. It holds fixed reversal potential \(E\) and concentration \(C\).
