Assessing the behavioral relevance of the hippocampal theta rhythm has proven difficult, due to a shortage of experiments that selectively manipulate phase-specific information processing.

Computational study of hippocampal-septal theta rhythm changes due to β-amyloid-altered ionic channels. [PDF]
Electroencephagraphy (EEG) of many dementia patients has been characterized by an increase in low frequency field potential oscillations. One of the characteristics of early stage Alzheimer's disease (AD) is an increase in theta band power (4-7 Hz ...

EEG cortical network reveals the temporo-spatial mechanism of visual search
This study aims to explore a method based on brain networks for implicit attention by using wavelet coherence as feature to identify individual targets in the visual field, find the optimal classification rhythm and time window, and investigate the ...

Independent theta phase coding accounts for CA1 population sequences and enables flexible remapping
Hippocampal place cells encode an animal's past, current, and future location through sequences of action potentials generated within each cycle of the network theta rhythm.

The Role of the Medial Septum—Associated Networks in Controlling Locomotion and Motivation to Move
The Medial Septum and diagonal Band of Broca (MSDB) was initially studied for its role in locomotion. However, the last several decades were focussed on its intriguing function in theta rhythm generation.

Novel insights into false recollection : A model of déjà vécu
The thesis of this paper is that deja experiences can be separated into two forms: deja vu, arising from the erroneous sensation of familiarity, and deja vecu, arising from the erroneous sensation of recollection.

The role of syllabic rhythm in speech perception across languages
The insertion of silences at regular intervals restores the intelligibility of English utterances that have been accelerated beyond comprehension, as long as the duration of the resulting speech-silence chunks falls within the theta rhythm of natural ...

Deciphering hippocampal place codes in weak theta rhythms
Local field potentials (LFPs) reflect coordination among neural populations, yet their exact relationship to neural computation remains unknown. One exception is the theta rhythm of the rodent hippocampus, which organizes sequential firing among place ...

Genetic dissection of theta rhythm heterogeneity in mice [PDF]
Rhythmic oscillatory activities at the theta frequency (4-12Hz) in the hippocampus have long-attracted attention because they have been implicated in diverse brain functions, including spatial cognition. Although studies based on pharmacology and lesion experiments suggested heterogeneity of these rhythms and their behavioral correlates, controversies ...
