Summary: The study proposes a habituation strategy for awake rats undergoing fMRI, which enables stable image acquisition with low motion artifacts by gradually training the rats over a period of three weeks. Effective habituation results in low stress levels and minimal head motion artifacts during fMRI, allowing for precise brain mapping of BOLD signals and supporting the discrimination of cognitive processes without stress confounds.

Summary: Menopause transition is characterized by vulnerability due to estrogen deficiency, which can have detrimental effects on the body such as chronic inflammation and increased risk of age-related disorders. Despite the beneficial effects of estrogen on neurological tissues, clinical evidence regarding hormone treatment in menopausal women is inconclusive. Studies have shown that improved verbal memory is a significant finding from research, highlighting the potential neuroprotective effects of estrogen.

Summary: The study identified a shared network of transient fMRI increases in subcortical arousal and cortical salience/attention networks, which were consistent across different tasks and study populations. Furthermore, it found that sustained activity in these networks was more variable, and the function of the transient pulse in these networks remains unknown.

Summary: The study utilized fMRI to evaluate brain maps generated from healthy individuals' response to olfactory stimuli, revealing that the left anterior insula is primarily activated by odorous stimuli and other cortical areas are also involved.

Summary: This study investigated the multimodal alterations of the dorsal attention network (DAN) in subjects with subjective cognitive decline (SCD) and amnestic mild cognitive impairment (aMCI), and found that these alterations were closely related to cognitive performance. The combined multiple indicators of DAN could serve as potential neuroimaging markers for the diagnosis of preclinical and early-stage Alzheimer's disease (AD).

Summary: The emergence of ultra-high field MRI scanners has enabled researchers to study the human brain in detail. This non-invasive technique allows for the observation of differences between cortical layers, and layer-specific fMRI can distinguish feedback and feedforward pathways, thus contributing to the understanding of brain function.

Summary: The study examined the test-retest reliability of dynamic functional connectivity (dFC) in functional magnetic resonance imaging (fMRI) under natural viewing condition, revealing significantly improved reliability compared to resting state. This suggests that naturalistic paradigms may enhance the study of functional brain networks using fMRI.

Summary: Functional magnetic resonance imaging (fMRI) is increasingly used to study the acute impact of psychedelics on the human brain. A systematic review of fMRI studies revealed substantial heterogeneity in design and methodology. However, the review identified consistent findings: psilocybin and LSD modulate connectivity in the sensorimotor-association cortical axis, while ketamine increases activation in the dorsomedial prefrontal cortex.

Summary: This study searched the literature on functional magnetic resonance imaging (fMRI) for the assessment of renal alterations in diabetic kidney disease. 24 publications were included in the study, with a total of 1550 subjects. The study found that renal blood flow (RBF) values were significantly lower in the DKD group compared to the HV group on ASL-MRI. The FA values were also significantly lower in the DKD group on DTI-MRI. There were no significant differences in the other parameters on BOLD-MRI or IVIM-DWI.

Summary: The study identified two distinct dynamic states of intrinsic connectivity patterns based on BLA and CMA using fMRI and K-means clustering in two groups of young healthy individuals. Higher skin conductance level was found in the integration state compared to the segregation state in another dataset. Additionally, machine learning analysis revealed that the time-varying BLA and CMA intrinsic connectivity patterns had higher predictive values for fluctuations in skin conductance level in the integration state.

Summary: Recent neuroimaging studies have provided insights into the neurobiological processes associated with ASD, with MRI revealing abnormal developmental trajectories, functional MRI highlighting disrupted neural networks, and PET/SPECT imaging indicating metabolic and neurotransmitter abnormalities contributing to aberrant neural circuits in ASD.

Summary: This study investigates the relationship between the brainstem nucleus locus coeruleus (LC) and functional disturbances in mild cognitive impairment (MCI) patients. It found that functional connectivity (fc) between LC and anterior cingulate cortex and left anterior insula was elevated in MCI patients, while the fc between LC and right temporoparietal junction and posterior cingulate cortex was decreased. Additionally, the study found a positive correlation between LC to right temporoparietal junction connectivity and MMSE scores in MCI patients, as well as hyperactivation of the left-insula salience network.

Summary: This study investigates the impact of arousal levels indexed by pupil area on the integration of large-scale brain networks using simultaneous resting state functional magnetic resonance imaging (fMRI) and pupillometry. The results show a decrease in between-network integration and inter-subject variability at low arousal compared to high arousal, with differences occurring across regions of multiple brain networks. State-dependent changes in network integration within hub regions suggest a brain state transition characterized by global synchronization and reduced network overlaps. Arousal modulation has a brain-wide impact on high-level between-network communications. Additionally, changes in fMRI signal correlation structures and the choice of global signal regression can influence conclusions when studying arousal modulations.

Summary: This clinical trial aims to investigate the neural and molecular mechanisms by which estradiol treatment improves symptoms of anhedonia and psychosis during the perimenopausal transition. The study will recruit 100 unmedicated women in the late-stage perimenopausal transition and assess clinical symptoms and neurobiological markers before and after estradiol treatment. This research will provide valuable insights into predicting, treating, and developing biomarkers for perimenopausal psychiatric symptoms.
