Sevoflurane-induced hypotension causes cognitive dysfunction and hippocampal inflammation in mice
Behav Brain Res. 2023 Sep 14:114672. doi: 10.1016/j.bbr.2023.114672. Online ahead of print.ABSTRACTSevoflurane commonly adopted for anesthetic in clinical practice, however, its influences on cerebral blood flow and cognitive function remain controversial. Herein, the sevoflurane-induced hypotension on arterial blood pressure, cerebral blood flow, cognitive function, and hippocampal inflammation was investigated in mice. A significant decrease in arterial blood pressure and cerebral blood flow was indicated by the sevoflurane anesthesia treatment. Moreover, sevoflurane-induced hypotension was associated with the impaired c...

Cessations of consciousness in meditation: Advancing a scientific understanding of nirodha sam āpatti
Prog Brain Res. 2023;280:61-87. doi: 10.1016/bs.pbr.2022.12.007. Epub 2023 Apr 24.ABSTRACTAbsence of consciousness can occur due to a concussion, anesthetization, intoxication, epileptic seizure, or other fainting/syncope episode caused by lack of blood flow to the brain. However, some meditation practitioners also report that it is possible to undergo a total absence of consciousness during meditation, lasting up to 7 days, and that these "cessations" can be consistently induced. One form of extended cessation (i.e., nirodha samāpatti) is thought to be different from sleep because practitioners are said to be completely ...

Differences in intracortical responses following non-noxious and noxious stimulation in anaesthetized rats
Brain Res. 2023 Sep 5:148564. doi: 10.1016/j.brainres.2023.148564. Online ahead of print.ABSTRACTCortical responses have been proposed as a source for the extraction of unique and non-subjective sensory information. The present study aimed to investigate if it is possible to distinguish between non-noxious and noxious cortical responses with two different types of anesthesia. Sixteen rats were randomly allocated to receive either Hypnorm/Dormicum (HD) or isoflurane (ISO) anesthesia. Each animal had a custom-made microelectrode array implanted in the primary somatosensory cortex to record the local field potentials and a cu...
