Theta Rhythm in Hippocampus and Cognition
2020Theta rhythm is a large 4–12 Hz oscillatory activity that is predominant during wake and REM (rapid eye movement) sleep in the hippocampus. Theta rhythm is generated by the interplay between neurons from the medial septum and entorhinal cortex, with local oscillators within the hippocampus.

Theta rhythm protects sleep replay
Science, 2018Neuroscience Hippocampal replay of place cell sequences during sleep is critical for memory consolidation in target cortical areas. How is the sequential organization of place cell assemblies maintained across different time scales? Drieu et al. compared periods when a rat either sat passively on a moving train or ran actively on a treadmill on the ...

The theta rhythm appears in the rat hippocampal electroencephalogram during exploration and shows phase locking to stimulus acquisition. Lesions that block theta rhythm impair performance in tasks requiring reversalofpriorlearning, includingreversalinaT ...

In many brain structures, in particular in the hippocampus, gamma oscillations appear near the crests of much slower, 4–11 Hz oscillations, called theta oscillations or theta rhythms. For an example, see Fig. 34.1.

Frontal Midline Theta Rhythm in Young Healthy Adults
Clinical Electroencephalography, 1997In this study, we examined the relationship between the frontal midline (Fm) theta rhythm that appears when a healthy subject is engaged in mental tasks and the theta rhythm which appears in the frontal region of healthy subjects during light drowsiness.

Structural hierarchies, theta rhythm, hippocampal function
2004 IEEE International Joint Conference on Neural Networks (IEEE Cat. No.04CH37541), 2005The connection between different structures being at different hierarchical level of the cortico-hippocampal formation and their functional role is discussed. At least three different functions, code generation, mood regulation and navigation is being integrated into a coherent conceptual framework.
