Longitudinal dream-content shift and void-like dissociative phenomenology around outpatient ketamine infusions in chronic low back pain: a case report.

Journal of Medical Case Reports July 13, 2026 Kei Torii, Ryo Nishitani

Altered-state phenomenology around ketamine may relate to longer-term changes in imaginal processes, but observations across routine care are scarce. We report an educational case focusing on pre-defined dream motifs over time, without making treatment efficacy claims. A 48-year-old Japanese man with severe chronic primary low back pain reported dreams during insight-oriented psychotherapy from...

Autonomic-salience stability as a candidate Gate for awake low-dose ketamine: a systems neuroscience framework with a clinical anchor

Frontiers in Systems Neuroscience July 1, 2026 Kei Torii, Maho Jinno

Ketamine responses vary across patients and sessions, suggesting that dose alone is an incomplete organizing principle. We propose a state-first Gate-Amplifier-Reintegration framework in which awake low-dose ketamine acts primarily as an Amplifier of transient network flexibility, whereas autonomic-salience stability is treated as a candidate Gate that may shape whether this flexibility remains...
