Detailed Description

A synapse.

This class implements a simple synapse. Main feature is the transformation of digital signals from an Event object (usually a neuron) to analog values of a StochasticProcess object, which then are part of the membrane equation of another neuron. Since a synapse usually connects from one single neuron to another single neuron, this class is set to be active as default, i.e. is forwarded automatically and you don't have to use proceedToNextState() and prepareNextState() inside your program.

Constructor & Destructor Documentation

Synapse::Synapse	(	Time *	time,
		StochasticEventGenerator *	e,
		double	weight,
		double	revPot,
		const string &	name = "",
		const string &	type = "Synapse"
	)

Construct.

This will construct a simple synapse, which only has the values 1.0 (just after a pre-synaptic spike) or 0.0 (otherwise).

Parameters

e	object providing the events (spikes), i.e. the pre-synaptic neuron.
weight	synaptic weight
revPot	reversal potential
name	object name
type	object type

Member Function Documentation

virtual string Synapse::getParameter ( const string &  name ) const

virtual

Get parameter.

In a derived class, override this to handle every parameter you implement. If a parameter is described using multiple strings separated by space, this indicates a parameter of a parameter.

Parameters

name	name of parameter

Reimplemented from Parametric.

Reimplemented in SimpleSynapse.

virtual void Synapse::setParameter ( const string &  name, const string &  value  )

virtual

Set parameter.

Sets the value of a parameter using strings. If a parameter is described using multiple strings separated by space, this indicates a parameter of a parameter.

Parameters

name	name of parameter
value	value of parameter (used with operator<<)

Reimplemented from Parametric.

Reimplemented in SimpleSynapse.
