A live brain that tells you what it does and what it cannot.
Type a feeling or a metaphor. The interface returns the regions the published literature associates with that kind of input. Every region carries a confidence band and a citation, and every answer carries the caveat that activation is association, not proof. Most tools in this space hide that line. We put it on the screen.
Your phrase is interpreted by a language model constrained to a fixed region atlas. It can read novel metaphors, but it may only return regions that exist in our validated list.
If no key is set or the model call fails, a built-in citation-grounded engine answers instead, so an investor demo never breaks. Both paths return the same honest shape.
Confidence is capped at moderate. No answer claims certainty, because reverse inference forbids it. The caveat is attached to every response by the server, not the model.
The regions the interface can surface
A schematic teaching atlas, not an MNI coordinate map. Each region is scoped to associations the literature supports.
Associated with working memory, planning, and cognitive control. In the cognitive-debt work, this is part of the network that disengages when reasoning is offloaded to AI.
Associated with linking emotion to value and decision making, and with self-referential meaning.
Associated with the integration of negative affect, pain, conflict, and cognitive control.
Associated with interoception, the felt sense of the body, and with disgust and urgency. Activation here does not prove any single feeling.
Popularly the 'fear center,' but meta-analysis shows it is not fear-specific: it responds to salience across many states, including sadness. The clearest case for reading it as an association, never a verdict.
Associated with episodic memory and the binding of experience over time.
Associated with reward anticipation, wanting, and motivation.
A central relay associated with routing sensory and motor signals across the cortex.
Part of the default mode network, associated with self-referential thought, mind-wandering, and rumination.
Associated with the planning and execution of voluntary movement.
Associated with hearing, and with the processing of speech and language.
Associated with early visual processing, including visual metaphor and imagery.
Associated with arousal, autonomic response, and defensive reactions such as freezing or the urge to flee.
Classically motor coordination, increasingly associated with timing and aspects of cognition and affect.
Every association traces to a source. See the full sources list.
