The autonomic nervous system: Time for a conceptual reframing?

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The sympathetic, parasympathetic and enteric branches of the autonomic nervous system (ANS) are considered separate entities in the current model of the nervous system (A). We propose a simpler model that avoids the use of the term ‘the autonomic nervous system’ (B).

Dual cholinergic and serotonergic excitatory pathways mediate oxygen sensing in the zebrafish gill

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The present study identified two sub‐populations of gill oxygen sensing neuroepithelial cells (NECs) distinguishable by their stored neurotransmitters – serotonin (5‐hydroxytryptamine, 5‐HT) or acetylcholine (ACh). Using transgenic Tg(elavl3:GCaMP6s) zebrafish, which express an endogenous calcium reporter in neurons, we ...

Drug‐Related Engrams and Their Role in the Persistence and Recurrence of Drug‐Related Behaviors

open access: yesHippocampus, Volume 35, Issue 6, November 2025.
ABSTRACT Memory is a cornerstone of human behavior, and addiction offers a compelling model of its persistence and plasticity. The scope of engram research has rapidly expanded to include addiction‐related phenomena. Addiction‐related memories, like strong aversive memories, are often highly resistant to extinction and can continue to drive relapse ...

Cannabinoid CB2 receptor‐mediated analgesia: mechanism‐based insights and therapeutic potential

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 21, Page 5090-5118, November 2025.
Agonists of the cannabinoid 2 (CB2) receptor have shown promise for the treatment of pain in a variety of animal models. However, despite current preclinical evidence supporting the use of CB2 agonists for pain, successful translation of findings from preclinical models to human patients is lacking.
