Lesion-deficit correlation studies have provided evidence that the critical neural substrate of pure alexia is damage to the posterior fusiform gyrus (pFG; Damasio and Damasio 1983; Binder and Mohr 1992; Cohen et al. 2003; Leff et al. 2006).
Lesion-deficit correlation studies are important because they can provide a critical test of the necessity of the visual processing carried out by the left pFG and also reveal novel insights about the basis of visual recognition deficits in pure alexia.
With this technique, we produced binarized lesion maps for each patient that were used to mask individual patients' functional MRI data, but were not used in the lesion-deficit correlations.
In view of the recency deficits, the correlations (Spearman) between recency memory (D2) and lesion volume (septal hippocampus and total hippocampus) were examined.
The application of the SWDI in an agricultural area of Spain presented good results at both daily and weekly time scales when compared to two climatic water deficit indicators (average correlation coefficient, R, 0.6) and to agricultural production.
To examine whether volume reduction and decreased D3 receptor expression in the PFC and decreased DAT expression in the NAcc are associated with hyperlocomotion, impulsivity, and attention deficit, we conducted correlation analyses between behavioral and brain alterations.
The ABA level increases in the roots of this plant during water deficit conditions in correlation with the activation of defense mechanisms [ 17].
61 Unfortunately, most of the exercise studies for weight reduction did not measure the total caloric deficit and its correlation with the loss of body mass.
(DOCX 59 kb) Additional file 3: Potential deficits within-category correlation.
Along key steps of the CD8 stimulation process (activation, regulation, and effector function), we have identified transcriptional alterations that may help understand CD8 functional deficits observed in correlation to rapid progression and AIDS.
If we assume that all AC subjects have a similar overall attention deficit, then a negative correlation would be expected between rotation and target errors: subjects whose performance in one task is affected more than average would be expected to be affected less than average on the other task.
