Human motor-cortex intracortical facilitation
Experimental species, exposure and limitations are retained on each linked claim.
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 acts on it
Yellow-cactus-pear consumption was associated with increased motor-cortex intracortical facilitation in the preliminary human study.
Experimental context and source evidence
- dose
- 400 g yellow cactus pear fruit versus white-fruit comparator; exact indicaxanthin amount unresolved
- duration
- 90 min after fruit; sessions separated by at least one week
- evidence_access
- Primary open full text, relevant results/methods and PubMed metadata.
- evidence_scope
- literature_reviewed; model-specific source-derived curation
- experimental_model
- Small healthy-male neurostimulation study
- limitations
- Whole-food single-blind preliminary study. Methods report 12 fruit/8 comparator participants and four comparator exclusions; participant accounting and fruit-color wording have inconsistencies. No isolated-compound efficacy or cognitive benefit was demonstrated.
