IntegrateAndFire 

Signifies a current which will cause the cell to behave like an integrate and fire neuron. There are many ways to describe an
Integrate and Fire mechanism, this one is based on the implementation in NEURON of the COBA IandF cell as described in Brette et al (2007)

Complex Type Information

Model

Attributes

QName Type Fixed Default Use Inheritable Annotation
g_refrac ConductanceValue required 
Conductance during the period t_refrac after a spike, when the current due to this mechanism is given by i = g_refrac*(v - v_reset), therefore a high value for g_refrac, e.g. 100 microsiemens, will effectively clamp the cell at v_reset
t_refrac TimeValue required 
Time after a spike during which the segment will be clamped to v_reset (clamping current given by i = g_refrac*(v - v_reset))
threshold VoltageValue required 
Voltage at which the mechanism causes the segment/cell to fire, i.e. membrane potential will be reset to v_reset
v_reset VoltageValue required 
Membrane potential is reset to this after spiking
