class
brian2.synapses.synapses.
SynapticPathway
(synapses, code, prepost, objname=None, delay=None, event='spike')[source]¶ Bases:
brian2.groups.group.CodeRunner
,brian2.groups.group.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 theSpikeQueue
at the begin of a runqueue
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 anyconnect
call.By default this function does nothing.
-
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 theCodeRunner.abstract_code
attribute.Does nothing by default.
