class braincell.channel.Cav3p2_MA2025_BC(size, g_max=Quantity(0.0008, 'mS / cm^2'), V_sh=Quantity(0., 'mV'), temp=Quantity(309.15, 'K'), name=None)#

Basket cell Cav3.2 low-threshold T-type calcium current.

The same \(m^2 h\) Cav3.2 kinetics and ohmic current law documented in Cav3p2_RI2021_SC, reused unchanged for the cerebellar basket cell model of (Masoli et al., 2025) [4]. The kinetics remain Destexhe’s 1992 implementation of the low-threshold current of (Huguenard & McCormick, 1992) [1], refitted to the human recombinant Cav3.2 recordings of (Vitko et al., 2005) [2] and transformed to 36 degrees Celsius with Q10 factors credited to (Coulter, Huguenard & Prince, 1989) [3].

Parameters:

See also

Cav3p2_RI2021_SC

The base class; the full equation set, the baked-in temperature conversion, the dead temp parameter and the g_max default divergence are documented there.

Cav3p2_MA2024_PC

The same mechanism imported for the human Purkinje cell model.

Notes

Ported from BC/channel/Cav3p2_MA25_BC.mod, which is byte-identical to SC/channel/Cav3p2_RI21_SC.mod except for its SUFFIX line. Accordingly this class overrides nothing: the constructor, both gate declarations and the four rate methods are all inherited from Cav3p2_RI2021_SC. Only the register_channel key and this docstring’s model citation differ. Per the bibliography’s attribution scan, this subclass contributes no rate-function code of its own; its zero literal overlap in that scan is an artefact of the constants living in the base class.

The MA2025 import-deviations tables list no TABLE removal, no derivimplicit -> cnexp substitution and no rate-refresh relocation for Cav3p2.
