The phrase "alter connections" is correct and usable in written English.
It can be used when discussing changes or modifications to relationships, links, or networks, whether in a technical, social, or metaphorical context.
Example: "To improve the system's efficiency, we need to alter connections between the various components."
Alternatives: "modify links" or "change relationships".
The resulting histogram showed that most nodes have only 1 or 2 altered connections and that only a few nodes have multiple altered connections.
Scientists also analysed the brain patterns of people in the study and saw that exposure to stress altered connections between brain regions in a way that may have affected capacity for self-control.
The study suggests that ghrelin may regulate the sensitivity to food rewards by altering connections in the brain's reward pathway, says William Colmers of the University of Alberta in Edmonton, Canada.
Reward and punishment exert their most important neural effects by altering connections within the basal ganglia.
The number of significantly altered connections among each of the 90 brain regions is illustrated in Figure 2(a).
While the number of significantly altered connections for each node ranges from 0 to 17, only a small subset of regions had more than 4 altered connections.
The Slt2 signalling pathway is thought to respond to changes in the plasma membrane when it is either stretched or has altered connections to the cell wall [ 11].
The mean and standard deviation were calculated for this node-connection distribution, and a threshold of mean + 2.326 standard deviation was used to select the nodes with the greatest number of altered connections.
If the value of the differences in each link with a threshold P < 0.0005 (uncorrected) is used to emphasize the severely altered connections to the nodes, a clearer pattern revealed that the frontal DMN nodes have increased connections to frontal nodes and decreased connections to limbic nodes.
To address the possibility that the previously mentioned frontal-limbic correlation is only valid for the orbital part of the superior frontal gyrus due to the specific function of this brain region and therefore cannot be generalized to other frontal DMN nodes, we lowered the threshold of importance to nodes with at least 6 altered connections.
