All 16,000+ curated records in the Pulse Brain catalogue, each one fully enriched — read, tier-graded, claims-extracted and cross-referenced. Filter by persona, evidence tier, sector, topic, study type, exclusions, date range or keyword to surface the interpretation behind the evidence, not just a list of titles.

Rows: organic · regenerative · pasture-fed · conventional. Columns: phytonutrients, minerals, fatty-acid profile, microbiome, human biomarkers. Bubble size = record count. Bubble colour = evidence strength (share of T1/T2 tier studies in the cell).
Live
Why it matters: the single most credible view for this catalogue — makes whole-system comparison possible without a single-metric argument. Cells with no bubble are genuine evidence gaps worth commissioning work on.
02 · Thematic Cluster Map
The recurring ideas.
Six theme clusters with their sub-themes — soil biology, crop nutrition, farming systems, human outcomes, policy, methodology. Sub-theme size = record count. Hover for record counts.
Live
Why it matters: reveals the shape of the literature without us designing the categories. Large sub-themes = mature research; isolated sub-themes = emerging or under-served.
03 · Consensus Spectrum
Where the literature agrees — and where it doesn’t.
Claims drawn from the Growing Health Report and the most-cited records in the catalogue, placed honestly across three tiers. Updated as the catalogue grows.
Why it matters: Vitagri doesn’t overclaim. Showing contested territory alongside the settled territory is a credibility multiplier — especially with journalists, policymakers and academic reviewers.
04 · Evidence Tier Pyramid
Not all evidence is equal.
Counts per tier in the filtered set. T1 = meta-analyses and systematic reviews; T2 = RCTs and large cohorts; T3 = observational and field-trial; T4 = narrative reviews, guidelines, commentary.
Live
Why it matters: quick signal on how much of any claim is meta-analysis-grade versus narrative. Apex = strongest synthesis; base = broadest but most cautious.
05 · Publication Timeline
When the science arrived.
Records by publication year, stacked by tier. Use the date-range filter to narrow the window.
Live
Why it matters: velocity curve for investors, inflection markers for academics. The dominant decade of any topic tells a story on its own.
06 · Geographic Distribution
Where the science is happening.
Top ten geographies in the filtered catalogue. UK shown in ochre for visual contrast with the broader international literature.
Live
Why it matters: directly counters the “is this just UK & EU focused?” question without needing a projection argument. Works for international partners and journalists.
07 · Topic × Variable Heatmap
Dense lens on the intersections.
Rows: top theme clusters. Columns: measured variables (soil carbon, microbial diversity, nutrient density, yield, biomarkers, mineral content). Darker cell = more records touching both.
Live
Why it matters: complements the bubble matrix at a different level of abstraction. Spot dense research corridors and under-covered intersections.
08 · Soil-to-Health Systems Diagram
The chain, link by link.
Practice → Soil → Plant → Food → Human. Live record counts on each link show where the evidence thickens and thins in your current filter view.
Live counts
Why it matters: the emotional anchor of the whole page. The image journalists and policymakers keep asking for — strong mechanistic links, fewer RCTs on the final human endpoint.
Brand piece: press / deck hero. Memorable, less literally useful. Would be promoted to live-data if we take the brand-visual direction — star positions based on maturity × volume scores.

A 30-day Research Partner pilot turns Pulse Brain into a branded portal with tailored ranking, AI-generated briefs and a governance audit at week 4. The founding cohort is opening now.
Pulse Lens is the visual explorer for Vitagri's Pulse Brain research catalogue — an interactive view of 16,000+ peer-reviewed studies and industry reports on soil health, farming systems, nutrient density and human health. Eight linked visualisations turn the raw catalogue into a map of where evidence exists, where it converges, and where it is thin.
1. Farming system × outcome (evidence bubble matrix)
Rows are farming systems (organic, regenerative, pasture-fed, conventional). Columns are outcomes (phytonutrients, minerals, fatty-acid profile, microbiome, human biomarkers). Bubble size is record count in each cell; bubble colour is evidence strength (share of Tier-1 / Tier-2 records — meta-analyses and RCTs). At a glance: which farming systems are best-evidenced for which outcomes.
2. Thematic cluster map — the recurring ideas
A treemap-style view of the topic tags that recur most across the catalogue. Cluster size = record count, colour = theme (Nutrition & health, Farming systems, Policy, Climate, Measurement & metrics). Surfaces the intellectual centre of gravity of the evidence base.
3. Consensus spectrum — where the literature agrees
Ranks topics by how much the underlying evidence converges versus disagrees. Topics to the left have strong cross-study agreement (e.g. processed-meat cancer risk); topics to the right are contested (e.g. absolute nutrient-density differences between organic and conventional systems). Drives editorial priorities for the Weekly Bulletin.
4. Evidence tier pyramid
Stratifies the whole catalogue by evidence tier: T1 (meta-analysis, systematic review) at the apex, T2 (RCT, large cohort), T3 (observational, field trial, case-control), T4 (narrative review, commentary, guideline) at the base. Lets readers weight claims appropriately and see the true density of high-tier evidence on any topic after filtering.
5. Publication timeline
Year-by-year record counts from the earliest catalogued paper (1995) to the present. Highlights acceleration in specific research areas (regenerative agriculture, soil microbiome) and long-standing ones (nutritional epidemiology).
6. Geographic distribution
Horizontal bar chart of record counts by country or region of study conduct. UK, USA, Europe and International (global or multi-country) dominate; shows under-studied geographies where Vitagri's framework could productively commission or curate research.
7. Density heatmap — intersections
A denser second view of the farming-system × outcome space, optimised for spotting research corridors (well-covered intersections) and gaps (under-covered cells that a research programme could target). Complements the bubble matrix at a different level of abstraction.
8. Systems view
A compact systems diagram showing how the evidence connects soil biology, farm practice, food composition and human health outcomes — the causal chain Vitagri's GroundUp Framework operationalises.
All visualisations respond to the Advanced Filters at the top of the page: persona (Farmer, Food Buyer, Investor, Academia, Nutritionist), tier, sector, topic, study type, exclusions, date range and keyword. Filter state is preserved when jumping to the Evidence Index or Pulse AI so the reader can drill from a chart bubble into the underlying individual records.
