A group of researchers from the University of Cambridge has recognized two brain events that may help to shed light on the side-effects of ketamine, an anaesthetic and pain relief drug. The study was aimed to understand the effect of therapeutic drugs on the brains of people living with Huntington’s disease and involved the use of electroencephalography (EEG) to monitor immediate variations in the animals’ brain waves once ketamine was applied. Researchers initially observed the irregular brain frequency oscillations caused by the drug which eventually became regular within a few minutes. Researchers hope that the findings could be helpful to explain how brain networks function both in the healthy brain and in neurological diseases like Huntington’s disease and schizophrenia.
