Cortical Mechanisms Contributing to Ketamine-Induced Dissociation.
Review in The Neuroscientist : a review journal bringing neurobiology, neurology and psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ketamine is a unique anesthetic agent that induces dissociative anesthesia, characterized by perceptual detachment, analgesia, and altered states of consciousness. Beyond its widespread use in anesthesia, subhypnotic ketamine dosing has emerged as a rapid-acting antidepressant and a valuable model for probing the neural mechanisms underlying consciousness and neuropsychiatric disorders. At the core of its effects are actions on cortical circuits, primarily through NMDA receptor and HCN1 channel antagonism, disinhibition of pyramidal neurons, and altered thalamocortical connectivity. This review brings together emerging findings from ketamine pharmacology, cell type-resolved and region-specific in vivo imaging, and systems neuroscience to define how ketamine alters cortical circuit dynamics to drive dissociation. We further explore the intriguing possibility that ketamine freely diffuses into and concentrates within intracellular compartments and, in doing so, modulates neuronal excitability, intracellular signaling, and an epigenetic state, even following a single dose. A deeper mechanistic understanding of these cortical and cellular processes will not only advance our knowledge of ketamine's complex pharmacology but may also inform new therapeutic strategies for treatment-resistant depression and facilitate the study of diverse states of consciousness.
