Heat topological analysis

Fig. 6. Topological analysis of 2-AG distribution in different layers of rat hippocampus. Selected microstructure from hippocampus was laser-cut under the microscope (A) and analyzed using a state-of-the-art microflow LC/MS system. A heat map was generated to show topological differences in 2-AG levels (B).

In a critical analysis of such correlations, Platt investigated three topological indices in multiparametric correlations p, w, and f. For heats of formation at absolute zero (-273°C) and for molar refractions of alkanes, biparametric correlations with f and p gave satisfactory results, For heats of vaporization, boiling points at normal pressure, and molar volumes, biparametric correlations with p and w proved adequate. For heats of formation of gaseous alkanes at 25°C, triparametric correlations had to be used.
