Editing Receptive field (section)

==Auditory system==
The auditory system processes the temporal and spectral (i.e. frequency) characteristics of sound waves, so the receptive fields of neurons in the auditory system are modeled as spectro-temporal patterns that cause the firing rate of the neuron to modulate with the auditory stimulus. Auditory receptive fields are often modeled as [[spectro-temporal receptive field]]s (STRFs), which are the specific pattern in the auditory domain that causes modulation of the firing rate of a neuron. Linear STRFs are created by first calculating a [[spectrogram]] of the acoustic stimulus, which determines how the [[spectral density]] of the acoustic stimulus changes over time, often using the [[Short-time Fourier transform]] (STFT). Firing rate is modeled over time for the neuron, possibly using a [[peristimulus time histogram]] if combining over multiple repetitions of the acoustic stimulus. Then, [[linear regression]] is used to predict the firing rate of that neuron as a weighted sum of the spectrogram. The weights learned by the linear model are the STRF, and represent the specific acoustic pattern that causes modulation in the firing rate of the neuron. STRFs can also be understood as the [[transfer function]] that maps an acoustic stimulus input to a firing rate response output.<ref>{{cite journal|doi=10.1080/net.12.3.289.316|volume=12|issue=3|title=Estimating spatio-temporal receptive fields of auditory and visual neurons from their responses to natural stimuli|journal=Network: Computation in Neural Systems|pages=289–316|year=2001|last1=Theunissen|first1=F.E.|last2=David|first2=S.V.|last3=Singh|first3=N.C.|last4=Hsu|first4=A.|last5=Vinje|first5=W.E.|last6=Gallant|first6=J.L.|pmid=11563531|s2cid=199667772 }}</ref> A theoretical explanation of the computational function of early auditory receptive fields is given in.<ref>{{cite journal| pmid=25822973|  doi=10.1371/journal.pone.0119032
