It is suggested that the study of time-varying aspects of FC can unveil flexibility in the functional coordination between different neural systems, and that the exploitation of these dynamics in further investigations may improve the understanding of behavioral shifts and adaptive processes.
A Baseline for the Multivariate Comparison of Resting-State Networks
A multivariate analytic approach that optimizes sensitivity and reduces unnecessary testing is introduced and is demonstrated by identifying the effects of age and gender on the resting-state networks of 603 healthy adolescents and adults.

Comparisons of subject‐specific, spatial concatenation, and group data mean subject‐level reduction strategies using PCA and probabilistic PCA (PPCA) show that computationally intensive PPCA is equivalent to PCA, and that subject‐ specific and group Data mean subject-level PCA are preferred because of well‐estimated TCs and SMs.

Correspondence between structure and function in the human brain at rest
It is proposed that by exploring where GM corresponds to function would aid in the understanding of both structural and functional connectivity and in turn the human connectome, and concludes that age has a significant effect on structural components.
Data Visualization in the Neurosciences: Overcoming the Curse of Dimensionality
Connectivity dynamics in typical development and its relationship to autistic traits and autism spectrum disorder
A “chronnectomic” approach was employed to evaluate transient states of connectivity using resting‐state functional MRI in a population‐based sample of 774 6‐ to 10‐year‐old children, and it was demonstrated that higher levels of autistic traits and ASD diagnosis were associated with longer dwell times in a globally disconnected state.
Nasal immunity is an ancient arm of the mucosal immune system of vertebrates.
It is found that NALT is present in rainbow trout and that it resembles other teleost mucosa-associated lymphoid tissues, and is capable of mounting strong anti-viral immune responses following nasal delivery of a live attenuated viral vaccine.
