They also found that after the onset of hearing an elegant refinement of the neuron's excitation function takes place.
This allowed the researchers to separately record the inhibition and excitation functions of the neurons.
Generally, for this type of optimization, a detailed model of the system would be developed that would represent the thermodynamic and physical relationships between the components of the system, and the dynamic response of the system to one or more standardized excitation functions would be simulated using a short time step [Jreijiry (2003), Park (2008), Riederir (2005), Treado (2011)].
