SynapticPathway class

(Shortest import: from brian2.synapses.synapses import SynapticPathway)

class brian2.synapses.synapses.SynapticPathway(*args, **kw)[source]

Bases: CodeRunner, Group

The CodeRunner that applies the pre/post statement(s) to the state variables of synapses where the pre-/postsynaptic group spiked in this time step.

Attributes

_initialise_queue_codeobj

The CodeObject initalising the SpikeQueue at the begin of a run

queue

The SpikeQueue

Methods

before_run(run_namespace)

Optional method to prepare the object before a run.

check_variable_write(variable)

Function that can be overwritten to raise an error if writing to a variable should not be allowed.

create_code_objects(run_namespace)

initialise_queue()

push_spikes()

update_abstract_code([run_namespace, level])

Update the abstract code for the code object.

queue

The SpikeQueue

before_run(run_namespace)[source]

Optional method to prepare the object before a run.

Called by Network.after_run before the main simulation loop starts.

check_variable_write(variable)[source]

Function that can be overwritten to raise an error if writing to a variable should not be allowed. Note that this does not deal with incorrect writes that are general to all kind of variables (incorrect units, writing to a read-only variable, etc.). This function is only used for type-specific rules, e.g. for raising an error in Synapses when writing to a synaptic variable before any connect call.

By default this function does nothing.

create_code_objects(run_namespace)[source]
initialise_queue()[source]
push_spikes()[source]
update_abstract_code(run_namespace=None, level=0)[source]

Update the abstract code for the code object. Will be called in before_run and should update the CodeRunner.abstract_code attribute.

Does nothing by default.
