threshold_lin_rate


Name:
threshold_lin_rate - rate model with threshold-linear gain function
Description:
 

threshold_lin_rate is an implementation of a nonlinear rate model with input
function input(h) = min( max( g * ( h - theta ), 0 ), alpha ).
Input transformation can either be applied to individual inputs
or to the sum of all inputs.

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.
mean double - Mean of Gaussian white noise.
std double - Standard deviation of Gaussian white noise.
g double - Gain parameter
theta double - First Threshold
alpha double - Second Threshold
linear_summation bool - Specifies type of non-linearity (see above)
rectify_output bool - Switch to restrict rate to values >= 0

Note:
The boolean parameter linear_summation determines whether the
input from different presynaptic neurons is first summed linearly and
then transformed by a nonlinearity (true), or if the input from
individual presynaptic neurons is first nonlinearly transformed and
then summed up (false). Default is true.

Receives:
InstantaneousRateConnectionEvent, DelayedRateConnectionEvent,

Sends:
