“…It is well known that beta and gamma in the cortex-basal ganglia network are modulated according to movement state (Bergman et al, 1994;Donoghue et al, 1998;Brown and Marsden, 1999;Aoki et al, 2001;Brown et al, 2001Brown et al, , 2002Cassidy et al, 2002;Levy et al, 2002;Lee, 2003;Masimore et al, 2005;Sharott et al, 2005;van der Meer and Redish, 2009). In contrast, the present results, and data showing negative power correlation between beta and gamma bands in humans (Fogelson et al, 2005), were obtained at rest.…”

Modulation of oscillatory activity through basal ganglia-cortical loops in specific frequency bands is thought to reflect specific functional states of neural networks. A specific negative correlation between beta and gamma sub-bands has been demonstrated in human basal ganglia and may be key for normal basal ganglia function. However, these studies were limited to Parkinson's disease patients. To confirm that this interaction is a feature of normal basal ganglia, we recorded local field potential (LFP) from electrodes in globus pallidus (GP) of intact rats. We found significant negative correlation between specific frequencies within gamma (Ϸ60 Hz) and beta (Ϸ14 Hz) bands. Furthermore, we show that fluctuations in power at these frequencies are differentially nested within slow (Ϸ3 Hz) oscillations in the delta band, showing maximum power at distinct and different phases of delta. These results suggest a hierarchical organization of LFP frequencies in the rat GP, in which a low-frequency signal in the basal ganglia can predict the timing and interaction of power fluctuations across higher frequencies. Finally, we found that dopamine D 1 and D 2 receptor antagonists differentially affected power in gamma and beta bands and also had different effects on correlation between them and the nesting within delta, indicating an important role for endogenous dopamine acting on direct and indirect pathway neurons in the maintenance of the hierarchical organization of frequency bands. Disruption of this hierarchical organization and subsequent disordered beta-gamma balance in basal ganglia disorders such as Parkinson's disease may be important in the pathogenesis of their symptoms.

“…Numerous experiments in recent years have also shown task-related alpha modulations in subdural surface grids (Arroyo et al 1993;Toro et al 1994;Towle et al 1995;Crone et al 1998;Ohara et al 2000;Crone et al 2001;Brunner et al 2005;Dalal et al 2008;Blakely et al 2009;Edwards et al 2009;Swann et al 2009;Fukuda et al 2010), including centimeter-scale coherence (Shen et al 1999;Aoki et al 2001;Brunner et al 2005). Tremblay et al (2004) reported decreases of alpha band power over frontal and motor cortex not only with finger movements but also with observations of finger movements.…”

“…We compared the frequency band where we typically observed an attentional effect (80-150 Hz) with two other frequency bands that have been previously used to denote gamma activity: 60-95 Hz (Bauer et al, 2006) and 31-60 Hz (Aoki et al, 2001). As can be seen in the plots in Figure 2 and 6, there is indeed some activity in these lower frequencies (30-80 Hz), although the maximum change typically occurs at higher frequencies.…”

Objective: To study the role of gamma oscillations (>30 Hz) in selective attention using subdural electrocorticography (ECoG) in humans. Methods:We recorded ECoG in human subjects implanted with subdural electrodes for epilepsy surgery. Sequences of auditory tones and tactile vibrations of 800 ms duration were presented asynchronously, and subjects were asked to selectively attend to one of the two stimulus modalities in order to detect an amplitude increase at 400 ms in some of the stimuli.Results: Event-related ECoG gamma activity was greater over auditory cortex when subjects attended auditory stimuli and was greater over somatosensory cortex when subjects attended vibrotactile stimuli. Furthermore, gamma activity was also observed over prefrontal cortex when stimuli appeared in either modality, but only when they were attended. Attentional modulation of gamma power began ∼400 ms after stimulus onset, consistent with the temporal demands on attention. The increase in gamma activity was greatest at frequencies between 80 and 150 Hz, in the so-called high gamma frequency range.Conclusions: There appears to be a strong link between activity in the high-gamma range (80-150 Hz) and selective attention.Significance: Selective attention is correlated with increased activity in a frequency range that is significantly higher than what has been reported previously using EEG recordings.
