Variability in Infants' Functional Brain Network Connectivity Is Associated With Differences in Affect and Behavior

Figures

  Figure 1. This figure shows the configurations for each of the network patterns in both a 2-dimensional 10-20 system layout and estimated projections onto cortical space of a 0–2 month-old Atlas (70). Each network consists of the average of all of the connections between red and blue channels of the same letter. In addition, the orange dots represent relevant 10-20 landmarks.

• 

  Figure 2. This figure shows the channels that are significantly different than zero for each of the networks. Channels in red, blue, and black represent significant changes for oxyHb, deoxyHb, and both oxy and deoxyHb respectively.

• 

  Figure 3. This figure shows the average levels of functional connectivity (oxyHb) and range of variability for each network. The boxplot horizontal lines from bottom to top reflect values for the lower quartile, median, and upper quartile respectively. *p < 0.05.

  Figure 4. This figure shows the unadjusted (solid line) and adjusted relation (covariates not shown: HIN, Control, maternal education) between functional connectivity (oxyHb) Z-score and regulation/orienting. Here, we found that connectivity in the FPN was positively associated with regulation/orienting (p = 0.049) whereas, connectivity in the DMN was negatively associated with regulation/orienting (p = 0.018). Shaded regions represent 90% confidence intervals for the raw (unadjusted) data.

  Figure 5. This figure shows the unadjusted (solid line) and adjusted relation (covariates: FPN, DMN, Control, income, age) between HIN functional connectivity (oxyHb) Z-score and negative emotionality. Here, we found a significant positive relation between the HIN and negative emotionality (p = 0.038). Shaded regions represent 90% confidence interval for the raw (unadjusted) data.
