Theta rhythms
WebFor decades, theta rhythms (∼5-10Hz) have been thought to play a critical role in memory processing in the entorhinal-hippocampal network. However, recent evidence suggests that successful memory performance also requires coupling of ∼30-100Hz gamma rhythms to particular phases of the theta cycle. R … WebThe role of midline frontal theta in human is discussed, with reference to its relation on consciousness. Clinical observations of the appearance of this theta activity under various conditions are reviewed. These include simulated diving, brain tumour, chemical intoxication, exercise, mental calculation, sleep and meditation. The mechanism of generation of this …

WebThe hippocampal theta rhythm is driven by the input from the septum so that the amplitude of theta bursts strongly depends on the activation of cholinergic neurons in the septum. The mechanism of theta generation involves inhibitory interconnections between septum and hippocampus. Figure 22.1. WebModeling shows how these functional mechanisms are related to physiological data from the hippocampal formation, including (1) the phase relationships of synaptic currents during theta rhythm measured by current source density analysis of electroencephalographic data from region CA1 and dentate gyrus, (2) the timing of action potentials, including the theta …

PAC is a well-studied neural coding motif that occurs when the amplitude of a high-frequency rhythm synchronizes with the phase of a low-frequency rhythm. fkj - go back homeWebAug 7, 2024 · The particular theta frequency is more controlled by PYR-to-PV + cell interactions rather than PV +-to-PYR cell interactions. We identify two scenarios by which theta rhythms can emerge, and they can be differentiated by the ratio of excitatory to inhibitory currents to PV + cells, but not to PYR cells. fkj-toss-sv/toss/tsz100.applicationTheta waves generate the theta rhythm, a neural oscillation in the brain that underlies various aspects of cognition and behavior, including learning, memory, and spatial navigation in many animals.
