StimulusOrgani (often abbreviated StimulusOrgani) is a theoretical construct in neurobiology used to describe a proposed centralized or semi-central sensory-processing organ responsible for the detection, transduction, and integration of environmental stimuli across modalities. The concept arose in debates about how early sensory processing interfaces with attention and action, and is frequently cited in discussions of multi-sensory integration and state-dependent perception. In theoretical models, StimulusOrgani is imagined to comprise receptor-like elements, neural encoding units, and feedback loops that modulate downstream circuits involved in arousal, learning, and motor responses.

Supporters argue that it helps explain rapid, prioritized responses to salient stimuli and the modulation of perception by internal states such as motivation and fatigue. Critics note that there is no widely accepted anatomically discrete structure corresponding to StimulusOrgani, and many researchers view the term as a useful abstraction rather than a real organ. In practice, the term is used to frame experiments on sensorimotor integration, attention, and neuromodulation, rather than to identify an established anatomical entity. The term appears mainly in theoretical papers and computational studies and is less common in standard anatomical texts.
