Selective lesions of medial septal GABAergic neurons disrupt Hippocampal Theta Rhythm Amplitude

open access: yes, 2010
Septal inputs critically modulate hippocampal function. However, the role of Medial Septal/Diagonal Band (MS/DB) neuronal populations in hippocampal theta rhythm generation is still under debate.

Dynamic gamma modulation of hippocampal place cells predominates development of theta sequences

open access: yeseLife
The experience-dependent spatial cognitive process requires sequential organization of hippocampal neural activities by theta rhythm, which develops to represent highly compressed information for rapid learning.

The Role of the Medial Septal Area in Regulating Theta Rhythm in the Anterior Cingulate Cortex

open access: yes, 2014
The theta rhythm is an EEG brain wave pattern in the frequency range of 4-8 Hz that is thought to be involved in learning and memory. Previous research has indicated that the medial septal area (MSA) of the brain controls the theta rhythm in the ...

Pacemaker Neurons for the Theta Rhythm and Their Synchronization in the Septohippocampal Reciprocal Loop

open access: yes, 2002
Hippocampal theta (4–10 Hz) oscillation represents a well-known brain rhythm implicated in spatial cognition and memory processes. Its cellular mechanisms remain a matter of debate, and previous computational work has focused mostly on mechanisms ...

Role of the Medial Septal Area in Regulating Prefrontal Theta Rhythm in Rats

open access: yes, 2007
Theta rhythms are electroencephalogram (EEG) waveforms between 4-12 Hz and are correlated with arousal, orientation, exploration, attention, learning and memory, motivational drives and emotions and movements.

Closed-loop control of theta oscillations enhances human hippocampal network connectivity

open access: yesNature Communications
Theta oscillations are implicated in regulating information flow within cortico-hippocampal networks to support memory and cognition. However, causal evidence tying theta oscillations to network communication in humans is lacking.

Theta Rhythm In Working Memory Post Valence Stimuli Presentation

open access: yes, 2013
While the influence of emotion on long-term memory processes is well-understood, it remains unclear whether the presence of emotional information improves or diminishes working memory (WM) performance.
