Vers un système ambulatoire d'enregistrement électro-encéphalographique chez le cheval libre de ses mouvements

Abstract : Electroencephalography (EEG) that has been extensively studied in humans presents also a large interest for studies on animal brain processes. However, the quality of the recordings being altered by the muscular activity most EEG recordings on animals have been obtained using invasive methods with deep implanted electrodes (under the skull). This requires anesthesia and can thus only be used in laboratory or clinical settings. As EEG is a very useful tool for both detecting brain alterations due to diseases or accidents but also to evaluate the arousal and attentional state of the animal, it seemed crucial to develop a tool that would make such recordings possible in the horse’s home environment, with the horse being allowed to be free moving. Such a tool should not be invasive nor involve visible interventions such as shaving the zone of implementation of the electrodes, nor cause discomfort to the horse as the usual other practice which consists in gluing them to the skin. In order to fulfill these requirements, we developed a novel EEG helmet adapted to the horse’s head that allows an easy and fast (less than 5 minutes) positioning of the electrodes and that can be used in the home environment on a free moving horse. In the present study, we show that this EEG helmet allows to obtain reliable recordings and opens entire new possibilities of investigation.
