“…Furthermore, significantly more electrodes showed speed-related theta-band power modulations compared with other frequencies [ 2 (4) ϭ 43.8, P Ͻ 10 Ϫ8 ]. These data are consistent with studies showing speed-related modulation of theta power in nonhuman mammals (Arnolds et al 1979;McFarland et al 1975;Rivas et al 1996;Whishaw and Vanderwolf 1973).…”

“…An alternate account of rodent hippocampal function, the sensorimotor integration hypothesis (Bland 1986;Bland and Oddie 2001), posits that these two types of theta oscillations incorporate incoming sensory information with existing motor plans to guide movement. Central to this hypothesis is the observation that hippocampal theta amplitude increases linearly with movement speed such that more rapid traversals require faster sensorimotor transformations, a finding documented in rodents (McFarland et al 1975), guinea pigs (Rivas et al 1996), cats (Whishaw and Vanderwolf 1973), and dogs (Arnolds et al 1979). To date, this phenomenon has not been demonstrated in humans.…”

Previous rodent studies demonstrate movement-related increases in theta oscillations, and recent evidence suggests that multiple navigationally relevant variables are reflected in this activity. Human invasive recordings have revealed movement-related modulations in delta and theta activity, although it is unclear whether additional behavioral variables are responsible for modulating this neural activity during navigation. We tested the role of delta and theta oscillations during navigation by addressing whether spatial-related processing, in addition to speed and task variables, modulates delta and theta activity. Recording from 317 hippocampal intracranial electrodes in 10 patients undergoing seizure monitoring, we observed increasing delta and theta power with increasing virtual speed at significantly more electrodes than would be expected by chance, replicating previous findings in nonhuman mammals. Delta and theta power were more consistently modulated, however, as a function of spatial view, including when subjects looked at stores in the virtual environment both to find a relevant goal or for spatial updating. A significantly larger proportion of electrodes showed view-related effects than speed-related modulations. Although speed, task, and spatial view affected delta and theta activity, individual electrodes were most frequently modulated by only one variable, rather than a combination of variables. These electrodes likely sampled independent delta and theta generators, which reflected movement-related and allocentric processing, respectively. These results extend previous findings in nonhuman mammals and humans, expanding our knowledge of the role of human hippocampal low-frequency oscillations in navigation.

“…Those findings and our data suggest that rewarded tones evoke theta waves. Episodes of high amplitude and regular theta rhythm typically appear during movement-related behavior like running or exploration (Pickenhain and Klingberg, 1967;Vandenvolf, 1969;Whishaw and Vandenvolf, 1973;Arnolds et al, 1979aArnolds et al, , 1979b but not during grooming, drinking or eating (Buzsiki et al, 1983). Theta rhythm can also be evoked in immobile animals by novel, startling or relevant events (Sainsbury and Montoya, 1984;Fontani et al, 1984;Sainsbury et al, 1987).…”

“…The key difference between the ferret and the rabbit seems to be the default mode of the hippocampal LFP during stillness; whereas rabbit Type 2 theta is evoked during immobility related periods of LIA, in the ferret, theta seems to be the dominant mode of activity regardless of locomotor state, at least in the behavioural task in this study. This may also be true of dogs, who are the closest phylogenetic relative to ferrets that have been studied; the example traces in the few papers recording from dogs show robust oscillatory activity resembling that observed in ferrets 65,75,76 . Cats, another close relative, also showed an abundance of Type 2 theta which was correlated to visual attention and was reported to be larger in amplitude than theta during locomotion 64,77,78 .…”

Theta oscillations are a hallmark of hippocampal activity across mammalian species and play a critical role in many hippocampal models of memory and spatial navigation. To attempt to reconcile the cross-species differences observed in the presence and properties of theta, we recorded hippocampal local field potentials in rats and ferrets during a localisation task designed to vary locomotion and sensory attention. Here we show that theta oscillations occur during locomotion in both the ferret and rat, however during periods of immobility, theta oscillations persisted in the ferret, contrasting starkly with the switch to large irregular activity (LIA) in the rat. Theta during immobility in the ferret was identified as Type 2 theta due to its sensitivity to atropine and was modulated by behavioural state, with the strongest theta observed during reward epochs. These results demonstrate that even under similar behavioural conditions, there is a variable relationship between theta and behavioural state across different species.
