synapses package

Package providing synapse support.

Exported members: Synapses

parse_synaptic_generator_syntax module

Exported members: parse_synapse_generator


handle_range(*args, **kwds) Checks the arguments/keywords for the range iterator
handle_sample(*args, **kwds) Checks the arguments/keywords for the sample iterator
parse_synapse_generator(expr) Returns a parsed form of a synapse generator expression.

spikequeue module

The spike queue class stores future synaptic events produced by a given presynaptic neuron group (or postsynaptic for backward propagation in STDP).

Exported members: SpikeQueue


SpikeQueue(source_start, source_end) Data structure saving the spikes and taking care of delays.

synapses module

Module providing the Synapses class and related helper classes/functions.

Exported members: Synapses


StateUpdater(group, method, clock, order[, …]) The CodeRunner that updates the state variables of a Synapses at every timestep.
SummedVariableUpdater(expression, …) The CodeRunner that updates a value in the target group with the sum over values in the Synapses object.
Synapses(source[, target, model, on_pre, …]) Class representing synaptic connections.


SynapticPathway(synapses, code, prepost[, …]) 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.
SynapticSubgroup(synapses, indices) A simple subgroup of Synapses that can be used for indexing.


find_synapses(index, synaptic_neuron)
slice_to_test(x) Returns a testing function corresponding to whether an index is in slice x.
