<p>Annotation and classification of serum metabolites with high relevance in the classification of temperament types.</p

Metabolites with high relevance in the classification of temperament types.

<p>Metabolite names, measuring technique and their VIP-Scores, number of occurrences in the outer cross-validation runs and nominal <i>p</i>-values for the Kruskal-Wallis-Test are shown for serum (S) and prefrontal cortex (PC) metabolites with high relevance in the classification of temperament types.</p><p>Metabolites with high relevance in the classification of temperament types.</p

Principal component score plot for prefrontal cortex and serum metabolites.

<p>Principal component score plot of the first two principal components for (A) the complete prefrontal cortex data and (B) the complete serum data. Symbols indicate the different temperament types, rhombs the fearful/neophobic-alert, circles the interested-stressed, triangles the outgoing/neophilic-alert, squares the subdued/uninterested-calm and crosses the indistinct temperament type.</p

Hierarchical clustering of metabolites with high relevance.

<p>Two way hierarchical clustering of (A) prefrontal cortex and (B) serum metabolite features with a high relevance in the classification of temperament types. Symbols indicate the different temperament types, rhombs the fearful/neophobic-alert, circles the interested-stressed, triangles the outgoing/neophilic-alert, squares the subdued/uninterested-calm and crosses the indistinct temperament type.</p
