class braincell.channel.Cav3p1_MA2024_PC(size, g_max=Quantity(0.00025, 'cm / s'), V_sh=Quantity(0., 'mV'), temp=Quantity(295.15, 'K'), q10=3.0, temp_ref=Quantity(310.15, 'K'), name=None)#

Purkinje cell Cav3.1 low-threshold calcium current, GHK drive.

The same \(p^2 q\) Cav3.1 kinetics and GHK current law documented in Cav3p1_MA2020_GoC, reused unchanged for the human Purkinje cell model of (Masoli et al., 2024) [3]. The kinetics remain the fit to (Iftinca et al., 2006) [1] published in (Anwar, Hong & De Schutter, 2012) [2].

Parameters:

See also

Cav3p1_MA2020_GoC

The base class; the full equation set, the GHK helper’s constants, the tau-embedded temperature handling and the header corrections are documented there.

Cav3p1_MA2024_PC_Frozen

Purkinje-cell variant with the GHK term’s voltage dependence removed from the autodiff graph. It is not a subclass of this class (see its Notes).

Cav3p1Test_PC24

Anonymous test variant of the same mechanism with the GHK drive replaced by a direct conductance-density current law.

Notes

Ported from PC/channel/Cav3p1_MA24_PC.mod. An earlier revision of this docstring named the source file Cav3p1_MA24_PC.mod, which does not exist; the shipped file uses the two-digit year code, and that is corrected here. That file is identical to GoC/channel/Cav3p1_MA20_GoC.mod except for its SUFFIX line and a dropped INDEPENDENT statement, neither of which affects the kinetics. Accordingly this class overrides nothing: the constructor, the gate declarations, the named Boltzmann/tau parameter block and the current method are all inherited from Cav3p1_MA2020_GoC. Only the register_channel key and this docstring’s model citation differ.

The MA2024 import-deviations tables list no TABLE removal, no integration-method substitution and no rate-refresh relocation for Cav3p1.
