Hugo Critchley

British clinical neuroscientist and psychiatrist. Foundation Chair in Psychiatry at the Brighton and Sussex Medical School from 2006 onward; previously at University College London's Wellcome Department of Imaging Neuroscience and the Institute of Neurology, where he completed his clinical and research training under Raymond Dolan. His research line connects autonomic nervous-system function — heart rate, blood pressure, sympathetic and parasympathetic balance — to subjective emotional experience and to specific psychiatric phenomena (panic, depersonalisation, anxiety, somatic-symptom presentations).

Stake§

Critchley's stake is methodological and clinical. He has built a long programme on the heartbeat-detection paradigm and its derivatives, and is senior author on much of the British contribution to the modern interoception literature. The post-2010 boom in interoception-and-psychiatry research runs partly through his collaborators (Sarah Garfinkel, Anil Seth) and is part of why Brighton-and-Sussex has become a hub of the field. The dual appointment in psychiatry and at the Sackler Centre for Consciousness Science is consistent with the work: clinical problems framed through a cognitive-neuroscience apparatus.

Critchley's 2004 Nature Neuroscience paper gave the modern interoception literature its operational handle. Where Craig 2002 named the construct anatomically, Critchley and colleagues used the heartbeat-detection task — judge whether external tones are synchronous with your own heartbeats — to produce a per-subject accuracy score correlated with right-anterior-insula activity and grey- matter volume. The cross-subject prediction is what made the paper land; the post-2004 boom in interoception-and-psychiatry research runs through this methodology.

The Sussex collaboration — Critchley with Sarah Garfinkel, Anil Seth, Adam Barrett, and Keisuke Suzuki — produced the post-2015 refinement of the field. The 2015 three-way distinction between accuracy, sensibility, and awareness is co-authored by Critchley, and Seth's inference frame sits alongside Critchley's autonomic-and-emotion programme in productive friction. The 2018 Khalsa Roadmap has Critchley as a senior author.

Critchley is the figure who turned interoception from a Craig-shaped anatomical proposition into a measurable individual-difference variable, and one of the senior figures who has held the methodological standards of the field steady as it has grown. His clinical orientation matters: the interoception he is interested in is the interoception that explains why some patients feel their hearts pounding through an anxiety attack and others do not.
