Large-brained females outperformed small-brained females in a numerical learning assay designed to test cognitive ability.
However, experimental evidence for the link between relative brain size and cognitive ability is surprisingly scarce and to date stems from a single study on brain size selected guppies (Poecilia reticulata), where large-brained females were shown to outperform small-brained females in a numerical learning assay.
However, recent advances in numerical methods and assay analysis software have rendered easier the fitting of the 5PL routine.
Studies of time-dependent biomass hydrolysis using the quantitative NIMS assay and numerical simulation warrant a couple of closing comments.
When assessing the cytotoxicity of nanoparticles, the colony formation assay yields numerical results, and is currently considered to be the best (most sensitive and reproducible) method of toxicity assessment.
The three assays gave numerical values for the hypoxic fraction that were not significantly different for any of the lines.
Hybrid individuals exhibiting slightly elevated genome size values typically displayed hybrid index scores closer to 1 (more annuus-like) and did not demonstrate elevated copy number estimates of LTR retrotransposons in direct assays of numerical abundance via quantitative PCR.
A total RNA assay determines a numerical value for the ratio of 28S ribosomal RNA (rRNA) subunit to 18S rRNA subunit, while an mRNA assay determines the percentage of rRNA contamination.
Second, we tested the cognitive ability of large- and small-brained individuals using an associative learning assay designed to investigate numerical quantification, a relatively advanced form of cognition [ 23].
Fluorescence in situ hybridization (FISH) assay allows rapid detection of numerical genetics aberrations in interphase nuclei in tumor cells.
