Neural Cue Reactivity
Concept
Neural cue reactivity refers to the brain's measurable response to cues associated with a behaviour, as studied with methods such as fMRI and EEG. It is the neural counterpart of the psychological phenomenon of cue reactivity.
What neural cue reactivity is
Neural cue reactivity is the brain’s measurable response to behaviour-associated cues, studied with fMRI or EEG. It is the neural counterpart of the psychological phenomenon of cue reactivity.
A mixed picture
A handful of small studies report heightened neural reactivity to sexual cues in people with compulsive sexual behaviour — for example, Voon et al. (2014) and Gola et al. (2017). But other work, such as Prause et al. (2015), found no addiction-like response. The field is small, heterogeneous, and contested, with no consensus biomarker.
What this means practically
There is no validated brain test for problematic pornography use, and these findings do not translate into clinical tools. Practical cue-management strategies remain useful regardless of how the neural debate resolves.
What the research shows
A handful of small neuroimaging studies report heightened neural reactivity to sexual cues in people with compulsive sexual behaviour, but results are mixed and contested, with some studies finding no addiction-like response.
Community observation
Community members' consistent reports of strong cue-triggered urges are the experiential background against which neural studies are interpreted, but they are not themselves neural evidence.
Practical implications
- The existence of some neural-cue-reactivity findings does not translate into a validated biomarker or a clinical test.
- Practical cue-management strategies remain useful regardless of the unresolved neural picture.
What we know
- Some studies find heightened neural response to sexual cues in compulsive sexual behaviour.
- Other studies do not find addiction-like responses.
What we don't know
- Whether neural cue reactivity predicts real-world behaviour or treatment outcomes.
- Whether group differences are cause, consequence, or pre-existing trait.
What is debated
- Whether heightened sexual-cue reactivity reflects addiction, high sexual interest, or both.

Limitations
- Studies are small, cross-sectional, and use different methods and definitions.
- Findings have been contested, and no consensus biomarker exists.
