The latter comparison shows that large BOLD differences can occur in the absence of firing rate differences.
To account for the potential contribution of phantom pain on the BOLD differences, chronic levels of phantom pain were assessed in each 1-handed individual.
More recently, however, researchers have begun to acknowledge that neurovascular coupling or oxygen use changes must be experimentally ruled out before BOLD differences can be used as evidence for differences of neuronal function between control and autistic groups (Dinstein et al., 2012; Feczko et al., 2012).
To empirically evaluate the role of the ΔCBF/ΔCMRO2 ratio in age-related BOLD differences and its relationship to performance, we utilized calibrated fMRI technology to assess visual cortex response to flickering annuli (Welford 1981; Hoge et al. 1999a, b; Pasley et al. 2007; Ances et al. 2009).
The increase in colors presented with UHD, matched with a bolder difference between black and white, Mullins explains, means "more dimensionality to your image, whether it's a canvas or a TV.
Because of the small number, missing values are not presented in the table Correct answers are highlighted in bold * difference is significant (2-tailed) T-tests for the mean number of correctly judged measures indicated that the overall score was comparable between the two groups (10.6 versus 10.5 useful and 4.3 versus 3.9 not useful).
A greater BOLD signal difference between target and source for the analogy than match task would more specifically reveal the neural correlates of mapping.
In bold: Significant difference between categories (p < 0.05) In the Cosali cohort, 66.9% of male workers and 57.7% of female workers exposed to handling loads at baseline also reported being exposed at follow-up (results not shown).
A greater BOLD signal difference between target and source for the analogy than match task would more specifically reveal the neural correlates of mapping. 1) That showed greater BOLD signal change for analogy than match tasks.
Therefore, the BOLD temporal differences may be due to neuronal activity, neurovascular coupling, or hemodynamic response differences between the SC and LGN.
