jaxley.pumps.CaPump

class CaPump(name=None)

Bases: Pump

Calcium dynamics based on Destexhe et al. 1994.

The following parameters are registered in channel_params:

Name	Default	Description	Unit
CaPump_gamma	0.05	Fraction of free calcium (not buffered).	1
CaPump_decay	80.0	Buffering time constant.	ms
CaPump_depth	0.1	Depth of shell.	um
CaPump_minCaCon_i	1e-4	Minimum intracellular concentration.	mM

The following states are registered in channel_states:

Name	Default	Description	Unit
i_Ca	1e-8	The calcium current.	mA/cm²
CaCon_i	5e-5	The intracellular calcium concentration.	mM

Parameters:

name (str | None)

channel_params: dict[str, Array]

channel_states: dict[str, Array]

current_name: str

update_states(states, params, modified_state, delta_t)

Update states if necessary (but this pump has no states to update).

Parameters:

• states (dict[str, Array])

• params (dict[str, Array])

• modified_state (Array)

• delta_t (float)

compute_current(states, params, modified_state, delta_t)

Return change of calcium concentration based on calcium current and decay.

Parameters:

• states (dict[str, Array])

• params (dict[str, Array])

• modified_state (Array)

• delta_t (float)

init_state(states, params, voltage, delta_t)

Initialize states of channel.

Parameters:

• states (dict[str, Array])

• params (dict[str, Array])

• voltage (Array)

• delta_t (float)

change_name(new_name)

Change the pump name.

Parameters:

new_name (str) – The new name of the pump.

Returns:

Renamed pump, such that this function is chainable.

property name: str | None

The name of the channel (by default, this is the class name).
