title: Three bands of oscillatory activity in the lateral geniculate nucleus of the cat visual system.
abstract: Neuronal responses in the cat lateral geniculate nucleus were analyzed with respect to oscillatory components in 5930 peri-stimulus time histograms recorded in 69 neurons. Oscillatory components were observed in three frequency ranges clearly separated from each other, i.e. in a lower range between 25 and 33 Hz (mean 27.8 Hz), in a middle range between 45 and 60 Hz (mean 52.5 Hz), and in a higher range between 75 and 100 Hz (mean 84.4 Hz); temporal variance within the neuronal populations showing oscillatory characteristics increased with higher frequencies. Although the frequency ranges of the oscillatory responses were clearly separated from each other, a functional dependence between these three populations of geniculate neurons appears to be possible; the numerical relationship of approximately 1:2:3 points to the possibility of a temporal coupling between distinct neuronal populations at an early stage of visual processing.
