By , Charles Stumpf was able to write a lengthy review of "Drug action on the electrical activity of the hippocampus" citing hundreds of publications Stumpf, , and in John Green, who served as the leader of the field during this period, was able to write an extensive and detailed review of hippocampal electrophysiology Green, A major contribution came from a group of investigators working in Vienna, including Stumpf and Wolfgang Petsche, who established the critical role of the medial septum in controlling hippocampal electrical activity, and worked out some of the pathways by which it exerts its influence. In the largest and most systematic of these studies, Cantero et al. A neural oscillatory pattern. Many later investigations have supported the general concept that hippocampal theta can be divided into two types, although there has been dispute about the precise properties of each type. Hippocampal theta rhythms in other species differ in some respects from those in rats. Another school, led by John O'Keefe, have suggested that theta is part of the mechanism animals use to keep track of their location within the environment. Theta rhythms are very strong in rodent hippocampi and entorhinal cortex during learning and memory retrieval, and are believed to be vital to the induction of long-term potentiation , a potential cellular mechanism of learning and memory. H 1 April Electroencephalography and Clinical Neurophysiology. Over the following decade came an outpouring of experiments examining the pharmacology and physiology of theta. Theta waves recorded from above the hippocampus are smaller, and polarity-reversed with respect to the fissure signals. Based on evidence from electrophysiological studies showing that both synaptic plasticity and strength of inputs to hippocampal region CA1 vary systematically with ongoing theta oscillations Hyman et al. Cortical theta is observed frequently in young children. Scalp EEG is generated almost entirely by the cerebral cortex , and even if it falls into a certain frequency range, this cannot be taken to indicate that it has any functional dependence on the hippocampus. Green and Arduini, in the first major study of this phenomenon, noted that hippocampal theta usually occurs together with desynchronized EEG in the neocortex , and proposed that it is related to arousal. In humans, hippocampal theta rhythm has been observed and linked to memory formation [1] [2] and navigation. The hippocampal theta rhythm depends critically on projections from the medial septal area , which in turn receives input from the hypothalamus and several brainstem areas. In rats, the slowest movements give rise to frequencies around 6. The answer is not yet entirely clear, but there is some evidence that type 1 and type 2 theta depend on different pacemakers. The signals picked up by scalp electrodes are comparatively small and diffuse and arise almost entirely from the cerebral cortex for the hippocampus is too small and too deeply buried to generate recognizable scalp EEG signals. This EEG pattern is known as the hippocampal theta rhythm. This has been reported for rats as well, but only when they are fearful Sainsbury et al. J Neurosci. Theta-frequency activity arising from the hippocampus is manifested during some short-term memory tasks Vertes, Conversely, theta oscillations have been correlated to various voluntary behaviors exploration, spatial navigation, etc. The first meaning is usually intended in literature that deals with rats or mice, while the second meaning is usually intended in studies of human EEG recorded using electrodes glued to the scalp. Behav Brain Res. As a rule, EEG signals are generated by synchronized synaptic input to the dendrites of neurons arranged in a layer. In Kramis, Bland, and Vanderwolf proposed that in rats there are two distinct types of hippocampal theta rhythm, with different behavioral and pharmacological properties Kramis et al. Human EEG recordings show clear theta rhythmicity in some situations, but because of the technical difficulties, it has been difficult to tell whether these signals have any relationship with the hippocampal theta signals recorded from other species. The outcome of all these factors is that the phase and amplitude of theta oscillations change in a very complex way as a function of position within the hippocampus. The dentate gyrus also generates theta waves, which are difficult to separate from the CA1 waves because they are considerably smaller in amplitude, but there is some evidence that dentate gyrus theta is usually about 90 degrees out of phase from CA1 theta. Basic EEG theory says that when a layer of neurons generates an EEG signal, the signal always phase-reverses at some level. 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, bats, and marsupials. Direct projections from the septal area to hippocampal interneurons also play a role in generating theta waves, but their influence is much smaller than that of the entorhinal inputs which are, however, themselves controlled by the septum. The hippocampal oscillations were associated with REM sleep and the transition from sleep to waking, and came in brief bursts, usually less than a second long. Type 2 theta is comparatively rare in unanesthetized rats: it may be seen briefly when an animal is preparing to make a movement but hasn't yet executed it, but has only been reported for extended periods in animals that are in a state of frozen immobility because of the nearby presence of a predator such as a cat or ferret Sainsbury et al. Vanderwolf and his colleagues, noting the strong relationship between theta and motor behavior, have argued that it is related to sensorimotor processing. In larger species of animals, theta frequencies are generally lower. Due to the density of its neural layers, the hippocampus generates some of the largest EEG signals of any brain structure. Some of the projections from the medial septal area are cholinergic; the rest are GABAergic or glutamatergic. The largest theta waves, however, are generally recorded from the vicinity of the fissure that separates the CA1 molecular layer from the dentate gyrus molecular layer. In humans, because invasive studies are not ethically permissible except in some neurological patients, the largest number of EEG studies have been conducted using electrodes glued to the scalp. Studies have shown an association of hypnosis with stronger theta-frequency activity as well as with changes to the gamma-frequency activity Jensen et al. Because of a historical accident, the term "theta rhythm" is used to refer to two different phenomena, "hippocampal theta" and "human cortical theta". From Wikipedia, the free encyclopedia. The faster an animal runs, the higher the theta frequency. Neuroscience Letters. There is also a distinction between sleep states: REM dreaming sleep is associated with theta; slow-wave sleep is associated with LIA. However the term "theta" had already become so strongly associated with hippocampal oscillations that it continued to be used even for rats. Cortical theta oscillations were observed during the transition from sleep and during quiet wakefulness; however, the authors were unable to find any correlation between hippocampal and cortical theta waves, and concluded that the two processes are probably controlled by independent mechanisms. Two types of theta rhythm have been described.

Soad thetawaves waves generate the theta rhythma neural oscillatory pattern that can be seen on an electroencephalogram EEGrecorded either from inside the brain or from electrodes attached to the scalp. When a rat is eating, grooming, or sleeping, the hippocampal EEG usually shows a non-rhythmic pattern known as large irregular activity or LIA.

Lesioning the medial septal area, or inactivating it with drugs, eliminates both type 1 and type 2 theta. Brain Res. Green and Arnaldo Arduini that mapped out the basic properties soad thetawaves hippocampal oscillations in cats, rabbits, and monkeys Green and Arduini, Their findings provoked widespread interest, in part because they related hippocampal activity to arousal, which was at soad thetawaves time the hottest topic in neuroscience.

The function of the hippocampal theta rhythm is not clearly understood. Several types of brain pathology can give rise to abnormally strong or persistent cortical theta waves. In rats, it can be observed in many parts of the brain, including nearly all that interact strongly with the hippocampus.

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 hippocampus. The lateral septal nucleus, a major recipient of hippocampal output, probably does not play an essential role in generating theta.

Vanderwolf made a strong argument that the presence of theta in the hippocampal EEG can be predicted on the basis of what an animal is doing, rather than why the animal is doing 2020 codes slot bonus. In rats, the most frequently studied species, theta wave rhythmicity is easily observed in the hippocampus, but can also be detected in numerous other cortical and subcortical brain structures.

There are other complications as well: the hippocampal layers are strongly curved, and theta-modulated inputs impinge on them from multiple pathways, with varying phase relationships.

The critical septal region includes the medial septal nucleus and the vertical limb of the diagonal band of Broca. They were not able to follow up on these initial observations, and it was not until that further information became available, in a very thorough study by John D.

Under certain conditions, theta-like oscillations https://2dvd.ru/2020/us-visa-application-procedure.html be induced in hippocampal or entorhinal cells in the absence of septal input, but this does not occur in intact, undrugged adult rats.

Green and Arduini described an inverse relationship between hippocampal and cortical activity patterns, with hippocampal rhythmicity occurring alongside desynchronized activity in the cortex, whereas an irregular hippocampal activity pattern was correlated with the appearance of large slow waves in soad thetawaves cortical EEG.

Thus, theta waves recorded from sites above and below a generating layer have opposite signs. Both of these are oscillatory EEG patterns, but they may have little in common beyond the name "theta". A major research problem has been to discover the "pacemaker" for the theta rhythm, that is, the mechanism that determines the oscillation frequency.

Green and Arduiniin their pioneering study of theta rhythms, reported only brief bursts of irregular theta in monkeys. In rats, these signals frequently exceed 1 millivolt in amplitude.

In the oldest EEG soad thetawaves dating back to the s, Greek letters such as alpha, beta, theta, and gamma were used to classify EEG waves falling into specific frequency ranges, with "theta" generally meaning a range of about 4β€”7 cycles per second Hz.

Cortical theta rhythms observed in human scalp See more are a different phenomenon with no clear relationship to the hippocampus.

Over the years this association has come to be stronger than the original association with soad thetawaves specific frequency range, but the original meaning also persists. The behavioral dependency also seems to vary by species: in cats and rabbits, theta is often observed during states of motionless alertness.

Most of the available information on human hippocampal theta comes from a few small studies of epileptic patients with intracranially implanted electrodes used as part of a treatment plan. Another theory links the theta rhythm to mechanisms of learning and memory Hasselmo, These different theories have since been combined, as it has been shown that the firing patterns can support both navigation and memory.

In bats, theta appears in short bursts associated with echolocation. Theta is not just confined to the hippocampus. Active movements such as soad thetawaves, jumping, bar-pressing, or exploratory sniffing are reliably associated with theta; inactive states such as eating or grooming are associated with LIA.

For type 2 theta, the supramammillary nucleus of the hypothalamus appears to exert control Kirk, For type 1 theta, the picture is still unclear, but the most widely soad thetawaves hypothesis proposes that the frequency is determined by a feedback loop involving the medial septal area and hippocampus Wang, Several types of hippocampal and entorhinal neurons are capable of generating theta-frequency membrane potential oscillations when stimulated.

Also, increased theta waves have been seen in humans in ' no thought' meditation. Green, JD Physiol Rev.

The frequency of the theta waves increases as a function of running speed, starting at about 6. In rats, hippocampal theta is seen mainly in two conditions: first, when an animal is running, walking, or in some other way actively interacting with its surroundings; second, during REM sleep [5]. In contrast to the situation in rats, where long periods of theta oscillations are easily observed using electrodes implanted at many sites, theta has been difficult to pin down in primates, even when intracortical electrodes have been available. In general, it is not safe to assume that observations of "theta" in the human EEG have any relationship to the "hippocampal theta rhythm". Thus the rat hippocampal EEG oscillation should not, strictly speaking, have been called a "theta rhythm". Green, JD; Arduini A J Neurophysiol.
