Summary: This study investigated the influence of anti-androgenic and progestin on the resting state functional connectivity (rs-FC) between the anterior cingulate cortex (ACC) and amygdala, while controlling for the androgenicity of progestin. The results showed that regardless of the androgenicity of progestin, rs-FC between the amygdala and frontal areas, as well as between ACC and temporoparietal areas, decreased with longer duration of HC use. However, the type of progestin had different effects on the gray matter volume of the left ACC and the connectivity between bilateral ACC and the right inferior frontal gyrus.

Summary: By using wide-field optical mapping, we simultaneously recorded pan-cortical neuronal and hemodynamic activity in awake, spontaneously behaving mice. We observed strongly fluctuating patterns of activity across diverse brain regions during quiet rest, which contribute greatly to interregional correlations. Dynamic changes in these correlations coincide with changes in arousal state. Simultaneously acquired hemodynamics depict similar brain-state-dependent correlation shifts. These results support a neural basis for dynamic resting-state fMRI, while highlighting the importance of brain-wide neuronal fluctuations in the study of brain state.

Summary: This study investigated the impact of cognitive reserve on functional connectivity in patients with Parkinson's disease and found that individuals with low cognitive reserve had weaker functional connectivity in the prefrontal cortex and basal ganglia. They also exhibited downregulation of attentional control networks and compensatory upregulation of medial frontal regions. These findings enhance our understanding of the mechanisms underlying cognitive impairments in Parkinson's disease.

Summary: This study used resting-state functional magnetic resonance imaging to analyze the subdivision and functional connectivity of the cingulate cortex (CC) in full-term neonates. The findings revealed specific connectivity patterns and functional lateralization in different subregions of the CC. These insights contribute to a better understanding of the functional specialization of the neonatal CC.

Summary: The study revealed that individuals with congenital amusia exhibit increased interhemispheric functional connectivity in the posterior part of the default mode network, particularly in the posterior superior temporal gyrus and posterior cingulate cortex, which were negatively correlated with music perception ability. These findings suggest that the immature state of the default mode network may serve as a reliable neural marker for amusia.

Summary: This study presents the first functional atlas of the mouse lemur brain and describes its cerebral networks for the first time, revealing both similarities and differences between mouse lemur and human brain networks. Mouse lemur high-level cortical networks were found to be similar to human networks, but not homologous.

Summary: Higher externalizing behavior is associated with increased resting-state attunement between the amygdala and ACC/OFC across adolescence and young adulthood. The association with amygdala-ACC connectivity is primarily driven by externalizing behavior at baseline, while the main effect on amygdala-OFC functional connectivity is driven by changes in externalizing behavior relative to baseline. No evidence was found for differential developmental trajectories of frontoamygdalar connectivity for different levels of externalizing behavior.

Summary: The study found that intra-FC related to the DMN is a prognostic marker that can potentially predict early remission of symptoms after anti-depressant treatment, helping to differentiate patients who reach remission from those who do not.

Summary: The study found that high-frequency sub-threshold taVNS can lead to sustained effects on the rsFC of brain regions involved in interoception and processing of pain in a cohort of healthy subjects, laying the foundation for future rsfMRI studies of high-frequency sub-threshold taVNS in clinical populations.

Summary: Sleep deprivation impairs cognitive abilities and is associated with changes in alpha-band oscillations. Resting-state alpha-band activation and functional connectivity are weakened after sleep deprivation, with the precuneus and posterior cingulate cortex playing crucial roles. Recovery sleep may partially reverse these changes, but not significantly.

Summary: This study suggests that early exposure to anesthesia in non-human primates can lead to alterations in cognitive, behavioral, and brain functions, particularly in the amygdala. The authors also found that resting-state functional connectivity MRI can detect changes in brain areas related to social behavior and astrogliosis.

Summary: This study conducted a systematic review and meta-analysis on the effects of ECT on brain connectivity in patients with depression. Significant changes in resting state functional connectivity were found in key brain regions such as the hippocampus and cingulate gyrus after ECT treatment. More studies with higher neuroimaging standards are needed to confirm these findings in different subgroups of depression.

Summary: This study investigated the utilization of resting-state blood oxygenation level-dependent signal for cerebrovascular reactivity mapping in patients with gliomas. The optimal frequency ranges for rs-CVR were determined to be 0.04-0.08 Hz and 0.02-0.04 Hz, showing higher correlations with breath-hold MRI results compared to resting-state fluctuation amplitude method.

Summary: The study aimed to construct a reliable brain atlas derived from older participants, identifying and subdividing major RSNs with high spatial reproducibility. Results showed spatial differences in RSNs derived from older versus younger populations, leading to the creation of a novel age-appropriate brain atlas, Atlas55+, for late adulthood RSN studies.
