Detailed Description

Current stimulus for neural items.

This stimulus applies a current stimulus to a neuron type of Node object. It can be configured to apply either a constant, repetitive, or bursting stimulus type. A bursting stimulus is one that has a repetitive stimulus that occurs in bursts. This works by setting the cycle on/cycle off duration to set the time periods for repetitive stimuli, and burst on/off for the burst periods. If you want to do a constant current then cycle on/off and burst on/off should be the start/end times of the stimulus. If you want a repetitive current then set burst on/off to the start/end time of the stimulus, but set the cycle on/off to some other values in between. If you want bursting then set cycle on/off to values less than the burst on/off values.

float * AnimatSim::ExternalStimuli::CurrentStimulus::GetDataPointer ( const std::string &  strDataType)
virtual

Returns a float pointer to a data item of interest in this object.

This is a generic method used to get a pointer to data variable of interest. It is used by a variety of systems in the simulation. The most prominent are the data charting and stimulus classes. Within this method we associate a variable with a string name. By passing in the name of the data type we are interested in we can recieve back a float pointer to that data type. We can use that to read or set the data item in other classes. For example, the data charting system gets the pointer and then each time it needs to log a data point it reads the value into an array.

Parameters
strDataTypename of the data item for which we are looking.
Returns
float pointer of the data item. If not found then it throws an exception.
Exceptions
IfDataType is not found.

+ Here is the call graph for this function:

void AnimatSim::ExternalStimuli::CurrentStimulus::Initialize ( )
virtual

Initializes this object.

After an object is loaded in it must be initialized before it can be used. This allows the object to retrieve any pointers or setup memory that it will need during execution. Each object is responsible for initializing any of its child objects, so you simply need to call this method on the containing class to init all child objects. It also calls VerifySystemPointers to make sure that the system pointers have been setup correctly.

void AnimatSim::ExternalStimuli::CurrentStimulus::QueryProperties ( CStdPtrArray< TypeProperty > &  aryProperties)

Queries this object for a list of properties that can be changed using SetData.

The method provides a list of the properties that can be set using the SetData method. It gives the property name and the type of data that should be passed to it. Valid date types are Boolean, Float, Integer, and Xml.

bool AnimatSim::ExternalStimuli::CurrentStimulus::SetData ( const std::string &  strDataType,

bool  bThrowError = true 
)
virtual

Set a variable based on a string data type name.

This is a generic method that can be used to set any variable in an AnimatBase object by specifying the name of the variable and a string representation of that data. The GUI uses this method to set data into variables in the simulation when the user changes them in the UI. The value string can be as simple as a float or int, or as complex as an xml packet. It is the developers responsibilty to know what type of data is needed and to process it accordingly.

Parameters
strDataTypestring name of the data type to set.
strValueThe string value of the data. It is up to the developer to determine what this should be. For example, in most cases it is simply a float and you just have to convert it to a float and make the appropriate mutator method call. However, it can be any type of string, including an entire xml packet. It is the developers responsibility to know how to set and process the data as required.
bThrowErrortrue to throw error if there is a problem. If false then it will not return an error, just return false.
Returns
true if it succeeds, false if it fails.

void AnimatSim::ExternalStimuli::CurrentStimulus::StepSimulation ( )
virtual

Step the simulation for this object.

This is called on an object each time it is stepped in the simulation. this is where its simulation code is processed. However, StepSimulation is not necessarily called every single time that the simulation as a whole is stepped. A good example of this is that neural modules can have different integration time steps. So a firing rate module may have a DT of 0.5 ms, while an integrate and fire model may have one of 0.1 ms. So the firing rate module would only get its StepSimulation method called every 5th time that the other module was called. This is all handed in the StepSimulation method of the Simulator and NervousSystem.
