How important it is to fine tune the frequency specificity in the ventral cochlear nucleus and central inferior collicular neurons, the following research work published in the Oct 2007 issue of "Journal of Neurophysiology" used multichannel microelectrodes to map the frequency specfic patterns of activity in VCN and Inferior colliculus neurons.

Multichannel techniques were used to assess the frequency specificity of activation in the central nucleus of the inferior colliculus (CIC) produced by electrical stimulation of localized regions within the ventral cochlear nucleus (VCN). Data were recorded in response to pure tones from 141 and 193 multiunit clusters in the rat VCN and the CIC, respectively. Of 141 VCN sites, 126 were individually stimulated while recording responses in the CIC.....................
