lin_rate


Name:
lin_rate - Linear rate model
Description:
 

lin_rate is an implementation of a linear rate model with
input function input(h) = g * h.
The model supports multiplicative coupling which can
be switched on and off via the boolean parameter mult_coupling
(default=false). In case multiplicative coupling is actived
the excitatory input of the model is multiplied with the function
mult_coupling_ex(rate) = g_ex_ * ( theta_ex_ - rate )
and the inhibitory input is multiplied with the function
mult_coupling_in(rate) = g_in_ * ( theta_in_ + rate ).

The model supports connections to other rate models with either zero or
non-zero delay, and uses the secondary_event concept introduced with
the gap-junction framework.

Parameters:
 

The following parameters can be set in the status dictionary.

rate double - Rate (unitless)
tau double - Time constant of rate dynamics in ms.
lambda double - Passive decay rate.
mean double - Mean of Gaussian white noise.
std double - Standard deviation of Gaussian white noise.
g double - Gain parameter
mult_coupling bool - Switch to enable/disable multiplicative coupling.
g_ex double - Linear factor in multiplicative coupling.
g_in double - Linear factor in multiplicative coupling.
theta_ex double - Shift in multiplicative coupling.
theta_in double - Shift in multiplicative coupling.
rectify_output bool - Switch to restrict rate to values >= 0
