class SynapseDef

This holds the data that makes up the definition of a synapse type.

Public Fields

T_SYNAPSE* source

For debugging and Reporting on Synapse properties

int RSEType

may be FACIL, DEPR, BOTH, NONE

double* TauDepr

These are pointers to [mean, stdev]

int PSGLen

Length of IPSG or EPSG waveform template

double* PSGTemplate

Pointer to IPSG or EPSG waveform template

float MaxG[2]

Maximum Conductance

bool LearnPos

Flag to indicate whether this synapse should receive Positive Hebbian learning

int nPosLearn

Number of entries in the positive learning table

double* PosLearnTable

Positive learning table.

bool LearnNeg

Flag to indicate whether this synapse should recieve Negative Hebbian learning

int nNegLearn

Number of entries in the negative learning table

double* NegLearnTable

Negative learning table.

Public Methods

SynapseDef()

Default Constructor.

SynapseDef(T_SYNAPSE* iSyn, ARRAYS* AR)

Primary constructor

~SynapseDef()

Destructor, notifies memory tracker that resourced have been freed

int SetLearning( int code )

Set the learning mode of the synapse

int Save( FILE* out )

Write SynapseDef to file.

void Load( FILE* in, char* nothing )

Read SynapseDef from file.

int getID()

Determines where this Synapse Definition appears in TheBrain's list of SynapseDefs.

Documentation

This holds the data that makes up the definition of a synapse type. It includes much of what was in the old SynapseRSE, SynapsePSG, and SynapseLearning objects, as well as some info from the synapse itself. Basically, everything that is the same across some type of synapse is included (or pointed to from) here, in order to minimize the size of individual synapses.

T_SYNAPSE* source

For debugging and Reporting on Synapse properties

int RSEType

may be FACIL, DEPR, BOTH, NONE

double* TauDepr

These are pointers to [mean, stdev]

int PSGLen

Length of IPSG or EPSG waveform template

double* PSGTemplate

Pointer to IPSG or EPSG waveform template

float MaxG[2]

Maximum Conductance

bool LearnPos

Flag to indicate whether this synapse should receive Positive Hebbian learning

int nPosLearn

Number of entries in the positive learning table

double* PosLearnTable

Positive learning table. Depending on conditions, a particular index is used

bool LearnNeg

Flag to indicate whether this synapse should recieve Negative Hebbian learning

int nNegLearn

Number of entries in the negative learning table

double* NegLearnTable

Negative learning table. Depending on conditions, a particular index is used

SynapseDef()

Default Constructor. Used when creating an empty structure for Load op

SynapseDef(T_SYNAPSE* iSyn, ARRAYS* AR)

Primary constructor

Parameters:

iSyn - Intermediate object generated from input containing synapse template
- AR User input data in parsed and structured format

~SynapseDef()

Destructor, notifies memory tracker that resourced have been freed

int SetLearning( int code )

Set the learning mode of the synapse

Parameters:

code - The type of learning this synapse will now use: 0 = NONE, 1 = +HEBBIAN, 2 = -HEBBIAN, 3 = BOTH

Returns:

0 on success, -1 on failure

int Save( FILE* out )

Write SynapseDef to file. An important note is that the class variable MaxG can be either a float or a double depending on the compiler options turned on at the time of compile. Therefore, if the version that saves MaxG uses the float format, then the version that loads MaxG must also use the float format.

Parameters:

out - file stream to write data

Returns:

number of bytes written

void Load( FILE* in, char* nothing )

Read SynapseDef from file. An important note is that the class variable MaxG can be either a float or a double depending on the compiler options turned on at the time of compile. Therefore, if the version that saves MaxG uses the float format, then the version that loads MaxG must also use the float format.

Parameters:

in - file stream to read data from
nothing - dummy pointer to use - will hopefully be removed later

int getID()

Determines where this Synapse Definition appears in TheBrain's list of SynapseDefs. Created to assist in Saving/Loading the Brain state.

Returns:

index into TheBrain->SynapseDefs (0..nDefs-1)

This class has no child classes.
