what in the world is this link to an unhelpful disambiguation page?
The '''spatio temporal receptive field''' (STRF) of a [[neuron]] represents which types of stimuli excite or inhibit that neuron. If [[linearity]] is assumed, the neuron can be modelled as having a time-varying firing rate equal to the [[convolution]] of the stimulus with the STRF.
==Auditory STRFs==
The example STRF here is for an [[Primary auditory cortex|auditory neuron]] from the area [[CM]]<!--what in the world is this--> of a male [[zebra finch]], when played [[conspecific]] birdsong. The colour of this plot shows the effect of sound on this neuron: this neuron tends to be excited by sound from about 2.5 kHz to 7 kHz heard by the animal 12 ms ago, but it is inhibited by sound in the same frequency rage from about 18 ms ago.

This STRF was generated with [http://strfpak.berkeley.edu/]STRFPAK: free software (registration required) to help estimate STRFs.
==Visual STRFs==
Visual STRFs can have the same dimension as movies.
