penicillin epilepsy (FGPE) are very similar to the spike-and-wave discharges of a human absence seizure. The use of rats has also been a common method for studying the spike-and-wave phenomenon. The
Genetic Absence Epilepsy Rats from Strasbourg (GAERS) and the inbred Wistar Albino Glaxo rats from Rijswijk (WAG/Rij) are the two main strains of rats that have been used in studies. The rats from these two strains show spontaneously occurring absence seizures that consist of typical spike-and-wave activity seen on an EEG. Rat genetic models have given data showing that the expression of absence seizures involves both the thalamic and cortical networks. In both models, electrophysiological data showed that spike-and-waves are initiated in the somatosensory cortex and then spread rapidly to the motor cortex and thalamic nuclei. Using in vivo intracellular recordings, it was found in the GAERS that spike-and-wave are initiated in layer 5/6 neurons of the somatosensory cortex. These neurons, show a distinctive hyperactivity associated with a membrane depolarization. They are suggested to lead the firing of distant cortical cells during the epileptic discharge.
78:, recorded the first EEG of an absence seizure in the 1920s, which led the way for the general notion of spike-and-wave electrophysiology. His first recording of a human EEG was made in 1924 using a galvanometer, but his results were very crude and showed small, undefined oscillations. He continued to refine his technique and increase the sensitivity to the galvanometer, in which he accumulated many EEGs of individuals with and without a brain malfunction or disorder. Among those tested were patients with epilepsy, dementia, and brain tumors. Hans Berger published his findings in 1933, however his results did not give a definitive characterization of the general EEG pattern seen during an epileptic seizure. In 1935, F.A. Gibbs, H. Davis, and W.G. Lennox provided a clear description of EEG spike-and-wave patterns during a petit mal epileptic seizure. An intracellular recording performed by DA Pollen in 1964 revealed that the "spike" aspect of the phenomenon was associated with neuronal firing and the "wave" aspect was associated with hyperpolarization.
263:. Absence seizures are generalized epileptic seizures that can be divided into two types, typical and atypical. Typical and atypical absence seizures display two different kinds of spike-and-wave patterns. Typical absence seizures are described by generalized spike-and-wave patterns on an EEG with a discharge of 2.5 Hz or greater. They can be characterized by an increase in synchronization of discharges in the thalamocortical circuitry. They can also be characterized by the acute onset and termination of the seizure. Atypical absence seizures have a higher frequency in children with severe epilepsy that suffer from multiple types of seizures. The spike-and-wave pattern seen here is more irregular than the generalized pattern and also seems to be slower. This irregular pattern is due to non-synchronous discharges of the thalamocortical circuitry. The onset and termination in these atypical absence seizures seem to be less acute than the typical absence seizures.

and juxtacellularly labeled. Medium oscillations (5–9 Hz) in both types of rats were noted to occur randomly in an unsynchronized pattern in relay and reticular neurons. However, spontaneous spike-and-wave discharges were observed in epileptic rats when the medium oscillations became synchronized, suggesting a dependence of the two. However, since medium ranged oscillations only developed into spike-and-wave discharges spontaneously, genetic factors also seem to contribute to the initiation of synchronized oscillations. These genetic factors may contribute to spike-and-wave oscillations by decreasing the action potential threshold in reticular cells, making them more excitable and potentially easier to initiate synchronized firing. Another study has shown that these medium oscillations have led to spike-and-wave discharges. The activity of the primary and secondary cortical regions, as well as the adjacent
275:(LGS) is a childhood epileptic encephalopathy characterized with generalized seizures and slow spike-wave activity while awake. LGS is a combination of atonic absences, tonic seizures, cognitive deterioration, and slow spike-wave activity in the EEG. This syndrome usually results from focal, multifocal, or diffuse brain damage and can be divided into symptomatic and cryptogenic types. Cognitive deterioration with high-frequency spike-wave activity affects most patients 2–9 years old with generalized seizures. The age of onset for LGS is between 1 and 10 years, between 2 and 6 years for symptomatic cases and 5 and 8 years for cryptogenic cases. Episodes can be triggered by modifications of treatment, which usually involves benzodiazepines, or changes in the conditions of life.
171:) in the thalamocortical network have also shown to display some role in the generation of spike-and-wave discharges (SWDs) associated with absence epilepsy. The different subtypes of mGlu receptors have a modulatory role on either excitatory or inhibitory synaptic transmission. There are conflicting hypotheses for the function of the many mGlu receptors with regards to epileptic seizures, however the role of the mGlu4 receptor is undisputed in the generation of SWDs, shown in animal models. In one study, knockout mice lacking mGlu4 receptors showed a disruption of glutamate and GABA release in the thalamocortical network and were resistant to absence seizures induced by low doses of
286:(OS), also known as early infantile epileptic encephalopathy (EIEE) with suppression-burst (S-B), is the most severe and the earliest-developing epileptic encephalopathy in children. This syndrome is characterized on an EEG by high voltage bursts and slow waves mixed with multifocal spikes alternating with almost flat suppression phases. The S-B will gradually begin to taper away at 3 months and disappear by 6 months. OS will transition to West syndrome or LGS with age. Tonic spasms are the main seizures observed in OS. Unlike LGS, the spike-and-wave pattern is consistent during both waking and sleeping states. Symptoms of OS include:
390:, and the new anti-epileptic drugs. Over the past 20 years, 15 new anti-epileptic drugs with positive outcomes have been introduced to the public. These new AEDs are aimed at improving the cost-benefit balance in AED therapy, improving tolerability profiles and reducing potential for drug interaction. Despite these major advances, there is always room for improvement, especially regarding the tailored treatment of individuals who have suffered adverse effects from older AEDs.
66:(AEDs) are commonly prescribed to treat epileptic seizures, and new ones are being discovered with fewer adverse effects. Today, most of the research is focused on the origin of the generalized bilateral spike-and-wave discharge. One proposal suggests that a thalamocortical (TC) loop is involved in the initiation spike-and-wave oscillations. Although there are several theories, the use of animal models has provided new insight on spike-and-wave discharge in humans.
179:) of normal mice protected against pentylenetetrazole induced seizures. Also, WAG/Rij rats show an increased expression of mGlu4 receptors in the nRT when compared to a control group of normal rats. These studies show that an increase in the expression and/or activity of mGlu4 receptors is associated with spike-and-wave discharges seen in absence seizures. This link between mGlur4 receptors and SWDs has led to the search for a selective mGlu4 receptor

367:(AEDs) is very prevalent. AEDs aim to slow down the excess firing, associated with spike-and-wave discharges, at the beginning of seizures. They can bring about serious adverse drug reactions so physicians need to be aware of the safety and admissibility for each drug. These adverse effects are a major source of disability, morbidity, and mortality. Some of the adverse effects, such as serious cutaneous,

In an epileptic seizure, there are periods of a sustained depolarization, which cause a train of action potentials followed by a repolarization and hyperpolarization phase. The train of action potentials constitutes the “spike” phase, and the repolarization and hyperpolarization constitute the “wave” phase.
355:. This continuous pattern during sleep, like other aspects of spike-and-wave activity, are not completely understood either. However, what is hypothesized is that corticothalamic neuronal network that is involved in oscillating sleep patterns may begin to function as a pathologic discharging source.
