“…In our view, current understanding of brain state in the hippocampus originates in the landmark insights of studies published in the 1960s and early 1970s by Cornelius Vanderwolf and colleagues (Vanderwolf, ; Vanderwolf, ; Whishaw & Vanderwolf, ; reviewed in O'Keefe & Nadel, ; Vanderwolf, ; O'Keefe, ). Vanderwolf's ideas were formulated with reference to experiments from his own lab and others (Grastyan, Lissak, Madarasz, & Donhoffer, ; Pickenhain & Klingberg, ; Stumpf, ; Vanderwolf & Heron, ) in which neural activity at the scale of the local field potential (LFP) was recorded in freely behaving animals during ethological behaviors, from sleep to feeding to exploration. In this experimental paradigm, the experimenter observes subjects' ongoing behavior with the aim to match behavioral patterns to LFP patterns.…”

Contemporary brain research seeks to understand how cognition is reducible to neural activity. Crucially, much of this effort is guided by a scientific paradigm that views neural activity as essentially driven by external stimuli. In contrast, recent perspectives argue that this paradigm is by itself inadequate, and that understanding patterns of activity intrinsic to the brain is needed to explain cognition. Yet despite this critique, the stimulus-driven paradigm still dominates - possibly because a convincing alternative has not been clear. Here we review a series of experimental findings in the hippocampus suggesting such an alternative. These findings indicate that hippocampal neural activity occurs in one of three brain states that have radically different anatomical, physiological, representational, and behavioral correlates, together implying different roles in cognition. This three-state framework also indicates that hippocampal neural representations follow a surprising pattern of organization at the timescale of ∼1 s or longer. Lastly, beyond the hippocampus, recent breakthroughs indicate three parallel states in cortex, suggesting shared principles and brain-wide organization of intrinsic neural activity.

“…The biggest controversy seemed to be over the impersistence of theta in Grastyan's cats trained in approach behavior (Grastyan et al 1959). Vanderwolf and Heron (1964) advanced the theory that the rhythm was related to "voluntary" movements. That it might be just a humming noise the brain makes when it is turned on was a hypothesis none of us cared to consider.…”

Theories of spatial cognition are derived from many sources. Psychologists are concerned with determining the features of the mind which, in combination with external inputs, produce our spatialized experience. A review of philosophical and other approaches has convinced us that the brain must come equipped to impose a three-dimensional Euclidean framework on experience – our analysis suggests that object re-identification may require such a framework. We identify this absolute, nonegocentric, spatial framework with a specific neural system centered in the hippocampus.A consideration of the kinds of behaviours in which such a spatial mapping system would be important is followed by an analysis of the anatomy and physiology of this system, with special emphasis on the place-coded neurons recorded in the hippocampus of freely moving rats. A tentative physiological model for the hippocampal cognitive map is proposed. A review of lesion studies, in tasks as diverse as discrimination learning, avoidance, and extinction, shows that the cognitive map notion can adequately explain much of the data.The model is extended to humans by the assumption that spatial maps are built in one hemisphere, semantic maps in the other. The latter provide a semantic deep structure within which discourse comprehension and production can be achieved. Evidence from the study of amnesic patients, briefly reviewed, is consistent with this extension.

“…This is reminiscent of previous modeling studies that showed that more asymmetric oscillators synchronize more quickly than more sinusoidal oscillators (Somers and Kopell, 1993) . Note that theta is generally faster and more asymmetric during running periods (Figure 3), and it is generally known that hippocampal theta is persistent during running periods (McFarland et al, 1975;Teitelbaum and McFarland, 1971;Vannderwolf, 1964) . Therefore, this observed correlation between cycle features and stationarity is likely partly a consequence of analyzing periods of movement and non-movement together.…”

Brain rhythms are nearly always analyzed in the spectral domain in terms of their power, phase, and frequency. While this conventional approach has uncovered spike-field coupling, as well as correlations to normal behaviors and pathological states, emerging work has highlighted the physiological and behavioral importance of multiple novel oscillation features. Oscillatory bursts, for example, uniquely index a variety of cognitive states, and the nonsinusoidal shape of oscillations relate to physiological changes, including Parkinson's disease. Open questions remain regarding how bursts and nonsinusoidal features relate to circuit-level processes, and how they interrelate. By analyzing unit and local field recordings in the rodent hippocampus, we uncover a number of significant relationships between oscillatory bursts, nonsinusoidal waveforms, and local inhibitory and excitatory spiking patterns. Bursts of theta oscillations are surprisingly related to a decrease in pyramidal neuron synchrony, and have no detectable effect on firing sequences, despite significant increases in neuronal firing rates during periods of theta bursting. Theta burst duration is predicted by the asymmetries of its first cycle, and cycle asymmetries relate to firing rate, synchrony, and sequences of pyramidal neurons and interneurons. These results provide compelling physiological evidence that time-domain features, of both nonsinusoidal hippocampal theta waveform and the theta bursting state, reflects local circuit properties. These results point to the possibility of inferring circuit states from local field potential features in the hippocampus and perhaps other brain regions with other rhythms.
