In NetLab and biological networks facilitation
describes a post-synaptic
response that closely tracks pre-synaptic
In biological terms facilitation describes a progressive increase in a synapse
's response to successive action potentials
during a train of stimulus pulses. Typically the input train of pulses could last up to a few seconds.
In NetLab's abstraction, facilitation describes a direct response to higher input levels with some level of attack and decay built in to the transfer function.
Facilitation was called reactive stimulus or reactive feedback in NetLab v0.1.
