pygrenade_vx.network.abstract.multicompartment.mechanisms.CurrentBasedSynapse

class pygrenade_vx.network.abstract.multicompartment.mechanisms.CurrentBasedSynapse(receptor_type: str = 'excitatory', *, strength: int = 500, time_constant: float = 1e-05, global_strength: int = 600)

Bases: pygrenade_vx.network.abstract.multicompartment.mechanisms.Mechanism

Current-based synapse.

Current-based synapse with a synaptic time constant and an input strength. If all synaptic inputs on a chip have the same strength, the synaptic current injected on the membrane is equalized between different synaptic inputs. Otherwise, the strength is directly translated to i_bias_gm of the synaptic input.

__init__(receptor_type: str = 'excitatory', *, strength: int = 500, time_constant: float = 1e-05, global_strength: int = 600)

Initialize a current based synapse.

Parameters

  • strength – Strength of the synaptic input.

  • time_constant – Time constant (in s) of the synaptic input.

  • global_strength – Global scaling of the synaptic input strength. Translates to synapse_dac_bias. Has to be the same for all synaptic inputs on a chip.

Methods

__init__([receptor_type, strength, …])

Initialize a current based synapse.

construct_parameter_space(lower_limits, …)
