Member Function Documentation

virtual int IzhikevichSpikingNeurons::AddGroup

(

neuron_parameters_struct *

group_params

)

[virtual]

Determines the total number of neurons by which the simulation should increase. This is a virtual function to allow polymorphism in the methods of various SpikingNeuron implementations. Allocates memory as necessary for group size and indices storage.

Parameters:

group_params

A neuron_parameters_struct instance describing a 2D neuron population size.

Returns:

The unique ID for the population which was requested for creation.

Reimplemented from SpikingNeurons.

virtual void IzhikevichSpikingNeurons::allocate_device_pointers	(	int	maximum_axonal_delay_in_timesteps,
		bool	high_fidelity_spike_storage
	)		[virtual]

Exclusively for the allocation of device memory. This class requires allocation of d_current_injections only.

Parameters:

maximum_axonal_delay_in_timesteps	The length (in timesteps) of the largest axonal delay in the simulation. Unused in this class.
high_fidelity_spike_storage	A flag determining whether a bit mask based method is used to store spike times of neurons (ensure no spike transmission failure).

Reimplemented from SpikingNeurons.

virtual void IzhikevichSpikingNeurons::copy_constants_to_device

(

)

[virtual]

Unused in this class. Allows copying of static data related to neuron dynamics to the device.

Reimplemented from SpikingNeurons.

virtual void IzhikevichSpikingNeurons::reset_neuron_activities

(

)

[virtual]

Resets any undesired device based data which is dynamically reassigned during a simulation. In this case, the current to be injected at the next time step.

Reimplemented from SpikingNeurons.
