“…It seems that the results obtained are reliable, that is why the procedure was not verified. The works by Weiergräber et al (2005), and also by Yoshida et al (2004), who used 3 electrodes in the case of rats, seem to confirm the above-mentioned opinion.…”

“…In spite of that, frequently used ani mals for this kind of procedures are canidae (Pampiglione 1963, Herin 1968, Susuki et al 1985, Pellegrino et al 1997, Ives et al 2006, felidae (Yamaguchi 2000), and pigs (Saito et al 2005). Rodents are often used, such as mice (Weiergräber et al 2005), rats (Ichinoze et al 1999, Kayama 2003, Kowalczyk et al 2004, Ashequr et al 2005 or guinea pigs (Mumford et al 2001). Numerous authors recommend the EEG examination together with alternative methods (MEG, MRI, PET, etc.…”

“…Such a procedure is justified by the fact that each species of animals has its own features, while the available literature does not specify sheep as research objects in an electroencephalographic technique. Standardization of the EEG record to a smaller extent is accepted by other researchers (Mumford et al 2001, Yoshida et al 2004, Weiergräber et al 2005, Ives et al 2006. They do not deny 10-20 system, however, they try to be more careful in its application among animal experimental methods.…”

RESUMENEl objetivo de este estudio es presentar el uso práctico de la electroencefalografía (EEG), demostrando el aspecto básico de EEG en ovejas, así como su utilidad en el análisis de las alteraciones provenientes del sistema nervioso central. Se examinaron 10 hembras híbridas de Oveja Merino Polaca, seleccionadas especialmente con fines experimentales. Debido a la falta de una fórmula unificada en el método de EEG en animales, se realizó un registro de potenciales provenientes de algunos puntos escogidos tras el experimento en cabezas de animales. Durante los experimentos realizados se demostró que la corteza cerebral de ovejas se caracteriza por una dinámica muy alta, hecho que fue demostrado al examinar las reacciones del sistema nervioso central a los factores tales como: el hambre, la estimulación auditiva o la inyección de xylazyna. La corteza cerebral de ovejas en el estado de reposo muestra una actividad bioeléctrica de una amplitud media de 30 μV y una frecuencia de 25 Hz, con lo cual se confirma la existencia del ritmo beta [β]. La aplicación de un estímulo acústico permite estimular el sistema nervioso central de oveja, lo que queda comprobado por una elevación de la amplitud media (por 23%) y de la frecuencia (por 21%) de la actividad bioeléctrica de la corteza cerebral, como también lo confirma el electroencefalograma conseguido. Los datos obtenidos demuestran que la zona que se caracteriza por tener el tiempo más corto de reacción es la zona del mesencéfalo, con un tiempo medio de reacción de 0,56 segundos (± 0,005 s). Se discute además la aplicabilidad de los experimentos, así como también la posibilidad de unificar el método de EEG.

“…Thus, although the data-logging device provides possibility for both frequent recordings over shorter periods, and for long-term experiments with periodic recordings in the same animal, the limited active logging timemakes the system less well suited for long-term experiments where continuous recordings from the same animal over weeks are required. For such applications, methods like low sampling rate telemetric systems (Weiergräber et al, 2005) seem at present to be preferable. It is, however, reasonable to assume that future improvements with respect to energy expenditure and improvements in the ratio of storage capacity to weight will significantly reduce the present short-comings of the logger-based system, and thereby contribute to further refinement of in vivo neurophysiological methods.…”

“…Recently, elegant telemetric devices have been developed for electrophysiological recordings without cables that may be useful in mouse epilepsy models relying on daily handling for seizure elicitation. The devices have been developed to decrease the restraint of the animal during recordings, and increase the flexibility of the recording situation (Weiergräber et al, 2005). However, such systems have so far showed considerable limitations both due to their low number of recording channels and low sampling rate.…”

Although alternative, noninvasive methods are being developed, current research on rodent sleep still almost exclusively relies on recording the electroencephalogram (EEG). EEG provides information about the electrical activity of the brain and is, in combination with the electromyogram (EMG), primarily used to distinguish the different sleep and wake states. This unit describes the technique used to record EEG and EMG signals in freely moving mice, under standard laboratory conditions or specific experimental protocols such as sleep deprivation (SD). In addition to its use to determine behavioral state, the EEG contains a wealth of information concerning rhythmic brain activity that can be extracted using signal analysis tools. We will describe the protocol for implantation of EEG and EMG electrodes, provide examples of experimental designs, and discuss data acquisition and analysis illustrating the type of information that can be obtained from the EEG in mice.
