NealCoverFunctions

Neuromorphic Embodied Agents that Learn (NEAL) based functions to isolate differences between different list synapse constructors.

class nmcog.spinnaker.specialfunction.neal.nealCoverClass.NealCoverFunctions(simName='spinnaker', spinnVersion=8)

Functions to isolate differences between different list synapse constructors.

Methods	Argument	Caller
nealProjection()	projection from a PyNN based spike source or a PyNN based Population projection into another PyNN based Population a list of connection parameter string describing the connection type; “excitatory” or “inhibitory”	usually to connect between two populations between cell assemblies
sameProjectionType()	two projections	nealApplyProjections()
nealApplyProjections()	(class must be instantiated because self.projections would have been the argument if this method had one)

Note:

• The PyNN based Population is usually a population within a cell assembly.

• The list of connection parameter is of the form such that

  • first element is the projection source (i.e. PyNN based spike source or PyNN based Population)
  • second element is the projection target (usually another PyNN based Population)
  • third element is a float type value representing weight value
  • fourth element is the self.DELAY (default = 0.1)

• The two projections must each be a list of the form [preNeurons, postNeurons, inhExc] or [preNeurons, postNeurons, inhExc, connectorList].

nealApplyProjections()

Collect the projections (i.e. self.projections) into projections that are pre post and type specific (via sameProjectionType()). And write them into one fromList.

nealProjection(preNeurons, postNeurons, connectorList, inhExc)

Given preNeurons, postNeurons, connectorList, and inhExc (string, “inhibitory” or “excitatory”) these four arguments are put into a list and reordered such that inhExc goes in front of connectorList. The list is then appended to the class attribute self.projections, a list.

sameProjectionType(projectionA, projectionB)

Checks if two given projections (between two cell assemblies) are of the same type. Returns Boolean. Note these projections are not self.projections.
