This provides a causal, time-resolved assay in which to test for the contribution of specific neural circuit elements that participate or contribute to the computations required for emergent behavior; optogentically controlled stimulation has recently been used in conjunction with fMRI to investigate the foundations of the BOLD fMRI signal.
= reference level; (b) Wald test for the contribution of the covariate to the logistic model; (c) Test for linear trend within individual categorical covariates.
My opinion is that it is now time for the design of a collaborative study large enough to have the power to separate trisomy 21 into all its component parts and to test for the contribution of folate/homocysteine gene polymorphisms to each of them.
To additionally explore the mechanisms responsible for the excitatory amino acid release in vivo, we tested for the contribution of alternative release mechanisms.
As an independent test for the contribution of vesicular filling to the scaling of GABAergic synaptic strength we made use of the fact that most released glutamate is buffered by uptake into glia cells [25].
The correlations within HLA identical and non-identical DZ twin pairs were compared to test for the contribution of HLA class II genes, whilst the correlations within HLA identical MZ and DZ twin pairs were compared to show the contribution of non-HLA genes.
To test for the contribution of differential sub-genome composition per chromosome, we assigned genes to chromosomes in a way that preserved the proportion of LF, MF1, and MF2 genes on each chromosome.
We use a dual isotope approach of δN and δC to test for the contribution of salmon nutrients to multiple trophic levels of litter-based terrestrial invertebrates below and above waterfalls that act as a barrier to salmon migration on two watersheds in coastal British Columbia.
Comparison with previous results without spatial error allows for explicit testing of the contribution that spatial error makes to refining exposure response relationships.
The data sets were analyzed using logistic regression, and likelihood ratio and Wald tests for the incremental contribution of X* were performed.
