Editor—We would like to attract the attention of anaesthetists and neurophysiologists to a case in which rats unexpectedly and transiently awoke from anaesthesia during a stereotaxic procedure performed as a part of an experimental lesional study. In our opinion, this important observation, described below, further contributes to the current knowledge on the functional mechanisms underlying the induction and maintenance of anaesthetic-induced unconsciousness.
The stereotaxic procedure served as the initial intervention for the study into the role of thalamic activity in EEG scalp-recordings and incorporated ibotenic acid (IBO)-induced lesions of different thalamic regions. The protocol
