Rhythms in the alpha band in cats and their behavioural correlates

Int J Psychophysiol. 1997 Jun;26(1-3):191-203. doi: 10.1016/s0167-8760(97)00764-2.


We describe two sets of rhythmical field potentials that may be recorded from the neocortex of the behaving cat: those at about 14 Hz ('mu' rhythms), in part of the somatic area SI; others at about 10 Hz ('alpha' rhythms), in part of the visual cortex (lateral gyrus). We report their precise localization, their thalamic correlates, their dependence upon a noradrenergic brainstem modulatory mechanism, and finally their possible functional significance.
