At least two types of theta rhythm have been described. The hippocampal theta rhythm is a strong oscillation that can be observed in the hippocampus and other brain structures in numerous species of mammals including rodents, rabbits, dogs, cats, and marsupials. Visa mer Theta 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. It can be recorded using various Visa mer Because of a historical accident, the term "theta rhythm" is used to refer to two different phenomena, "hippocampal theta" and "human cortical theta". Both of these are oscillatory EEG patterns, but they may have little in common beyond the name "theta". Visa mer In non-human animals, EEG signals are usually recorded using electrodes implanted in the brain; the majority of theta studies have involved electrodes implanted in the … Visa mer • Brain slice models of theta EEG activity Visa mer Although there were a few earlier hints, the first clear description of regular slow oscillations in the hippocampal EEG came from a paper written … Visa mer Due to the density of its neural layers, the hippocampus generates some of the largest EEG signals of any brain structure. In some situations the EEG is dominated by regular waves at 4–10 Hz, often continuing for many seconds. This EEG pattern is known as the Visa mer • Epilepsy Brain waves • Delta wave – (0.1 – 3 Hz) • Theta wave – (4 – 8 Hz) Visa mer Webb8 aug. 2003 · As during cued retrieval, these theta oscillations in the LA were significantly synchronized with hippocampal rhythms (0.207 ± 0.051 at 4.3 ± 0.8 Hz; P < 0.05, t = 2.627, Student's t test, n = 5). No comparable rhythmicity and synchronicity were observed during risk assessment in the shock context or the neutral context.
WebbTheta rhythm is the “rhythm with a frequency of 4 to under 8 Hz.”. Japanese scientists were the first who induced the EEG theta activity by administering a mental task consisting of continuous arithmetic addition. This theta activity was a train of rhythmic waves at a frequency of 6–7 Hz with maximum amplitude around the frontal midline ... WebbParoxysmal rhythmic theta waves appearing during early stages of sleep have long been recognized in the EEGs of normal children. A similar pattern with intermixed spikes appears to have a different correlation. We called this pattern 'hypnagogic paroxysmal spike wave activity' or 'hypnagogic PSW.' T …
