1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What it acts on
DSP-4 removal of forebrain noradrenergic projections did not eliminate modafinil wake promotion, while an adrenergic antagonist still suppressed it.
Experimental context and source evidence
- evidence_access
- Primary indexed abstract checked; full methods and figures not comprehensively reviewed.
- experimental_contrast
- {"intervention": "Noradrenergic projection lesion plus modafinil", "comparator": "Modafinil without lesion", "endpoint": "DSP-4 removal of forebrain noradrenergic projections did not eliminate modafinil wake promotion, while an adrenergic antagonist still suppressed it.", "effect_direction": "no_detected_change", "combination": "single", "conditions": []} Explicit extracted experimental comparison; source-derived draft.
- experimental_model
- Mouse pharmacological lesion experiment; adrenergic involvement does not require a simple obligatory projection relay.
- interpretation_status
- Source-derived extraction of a fact-checked reference; access is explicit, not independent raw-data verification.
- limitations
- Interpret only within the recorded preparation, exposure and comparator. The complete source passage retains qualifications; unspecified doses/timing have not been extracted here. No clinical efficacy, nutrient deficiency or unique molecular mediation is inferred.

In mice, removing forebrain noradrenergic projections with DSP-4 did not eliminate wake promotion, whereas an adrenergic antagonist still suppressed it. The interpretation involved dopamine–adrenergic interactions; the result prevents treating an intact locus-coeruleus projection as an obligatory relay.
