The challenge therefore in understanding the neural response is to demonstrate universality and to provide accurate predictions while avoiding overfitting.
In a series of recent papers following its original development, an approach is detailed which captures the transient response of peripheral neurons (i.e. the “adaptation response”) consisting of spontaneous (SR), peak (PA) and eventual steady-state activity (SS) of a sensory neuron. SS can be shown to be always bounded by the geometric and arithmetic mean of PA and SR. This elegant relationship has been shown to be obeyed in all measurements of auditory neurons and its demonstration requires no selection of parameters. Moreover, the lower bound is obeyed across all sensory modalities and organisms of different phyla.
In conclusion, this theory governs the sensory response universally and its veracity can be verified without the need of any fitting parameters in contrast to virtually all other approaches.
