Anaesthetic-dependent changes in gene expression following acute and chronic exposure in the rodent brain

Abstract Anaesthesia has been predicted to affect gene expression of the memory-related regions of the brain including the primary visual cortex. It is also believed that anaesthesia causes inflammation of neural tissues, increasing elderly patients’ chances of developing precursor lesions that lead...
