• The resilient phenotype elicited by ketamine against inflammatory stressors-induced depressive-like behavior is associated with NLRP3-driven signaling pathway (in mice! “these findings suggest that ketamine elicits a pro-resilient phenotype against inflammatory stressors-induced depressive-like behavior, an effect associated with the suppression of the NLRP3 inflammasome-driven signaling pathway.“)
• New trends in pharmacological control of neuropsychiatric symptoms of dementia (suggest to try (es)ketamine for Alzheimer’s)

• Effects of Ketamine and Midazolam on Simultaneous EEG/fMRI Data During Working Memory Processes (… “ketamine administration attenuated theta power increases and alpha power decreases and midazolam attenuated low beta band decreases to increasing WM load. Additionally, ketamine caused larger blood-oxygen-dependent (BOLD) signal increases in the supplementary motor area and angular gyrus, and weaker deactivations of the default mode network (DMN)…”)
