The theta rhythm appears in the rat hippocampal electroencephalogram during exploration
and shows phase locking to stimulus acquisition. Lesions that block theta rhythm impair …

Oscillations in neural activity are widespread throughout the brain and can be observed at
the population level through the local field potential. These rhythmic patterns are associated …

Neural rhythms can be studied in terms of conditions for their generation, or in terms of their
functional significance. The theta oscillation is a particularly prominent rhythm, reported to …

Spontaneous and hypothalamically induced theta activity was studied in rabbits lightly
anaesthetized with urethane or urethane-chloralose. Well-developed theta activity was …

In earlier chapters, the topics dealt with have included the anatomical basis for hippocampo-
cortical interaction, the general behavioural correlates of the rhythmic neural activity in the …

Hippocampal firing is organized in theta sequences controlled by internal memory
processes and by external sensory cues, but how these computations are coordinated is not …

Neural oscillations are important for memory formation in the brain. The desynchronization
of alpha (10 Hz) oscillations in the neocortex has been shown to predict successful memory …

Although anatomical, lesion, and imaging studies of the hippocampus indicate qualitatively
different information processing along its septo-temporal axis, physiological mechanisms …

Abstract Theta oscillations (6–12 Hz) have been theorized to provide a clocking mechanism
that can bring physically separated neurons together in time, thus potentially allowing for the …

The theta rhythm is the largest extracellular synchronous signal that can be recorded from
the mammalian brain and has been strongly implicated in mnemonic processes of the …
