Summary: With the progression of an aging society, cognitive aging has become an urgent concern. This study uses the senescence-accelerated mouse-prone 8 (SAMP8) model to investigate molecular changes in the brain cortex, identifying key functional alterations and candidate genes associated with brain aging, as well as pivotal hub genes involved in these functional domains.

Summary: Our study explored the impact of repeated exposure on intersubject synchrony in the brains of young and older adults. Using fMRI, we measured brain responses to familiar and novel stimuli. Surprisingly, synchrony was not influenced by the amount of exposure, as both young and older adults showed more synchrony to novel stimuli. Synchrony differences were found in various brain regions, emphasizing the importance of considering exposure effects in future studies.

Summary: This study demonstrates that lactate, produced by astrocytes through aerobic glycolysis, is used as an oxidative fuel by neurons in hippocampal tissue. The presence of excess glucose does not hinder the utilization of lactate for oxidative metabolism. Neurons take up lactate from the extracellular space via a neuronal lactate transporter, supporting the concept of an inward flux of lactate for neuronal oxidative metabolism.

Summary: Albiflorin demonstrates rapid antidepressant effects in animal models of depression by restoring common metabolic abnormalities in the hippocampus, particularly in phospholipid and tryptophan metabolism, through mechanisms involving the suppression of hippocampal cytosolic phospholipases A2 and normalization of the kynurenine pathway of tryptophan metabolism. This study provides insights into the homogeneous metabolic mechanisms of depression and suggests a potential rapid treatment approach targeting dysregulated neurometabolic pathways.

Summary: Studies indicate a close relationship between neural-vascular coupling and cognition, challenging the hemodynamic equivalence assumption. Through research elucidating the relationships between cognition, cerebrovascular dynamics, and aging, a theory about the decline in processing speed in aging and its relation to age-related neural-vascular coupling changes has been proposed.

Summary: Recent studies emphasize the important role of the principal inhibitory neurotransmitter GABA in motor performance during aging. Behavioral results indicate poorer motor performance in older adults compared to young adults. Moreover, a transient task-related decrease in GABA+ levels was observed during task execution, which was linked to task-related brain activity patterns.

Summary: It is suggested that specific forms of cognition in older age rely largely on late-life specific mechanisms. However, using task-fMRI, researchers found that the functional foundations of successful episodic memory encoding adhere to a principle of lifespan continuity, with no evidence of age-specific mechanisms. The study provides novel support for a broader perspective on memory aging that considers maintenance and decay of episodic memory throughout life rather than just in old age.

Summary: The study found that older adults show dampened response to faces with lower trustworthiness compared to young adults, supporting the idea of reduced sensitivity to cues of untrustworthiness in aging. Additionally, the results extend evidence of an age-related positivity effect to the evaluation of face trustworthiness.

Summary: In this study, computational models were used to investigate the role of the thalamus in generating brain synchrony at rest. The findings suggest that the structural connectivity of the thalamus is not its primary contribution to brain synchrony. Instead, the thalamus plays a critical role in driving cortical activity.

Summary: The study suggests that using MPC inhibitor UK 5099 in rats can alleviate LPS-induced fever, reduce hypothalamic mitochondrial function, and neuroinflammation. Pre-treatment with UK 5099 can affect LPS-induced oxygen consumption, ATP synthesis, and spare capacity, decreasing mitochondrial H2O2 production. Additionally, UK 5099 treatment can decrease the secretion of proinflammatory cytokines and the immunoreactivity of inflammatory transcription factors in rat POA microcultures after LPS stimulation.

Summary: The act of remembering everyday experiences affects our perception of the world, future thinking, and self-perception. However, the ability to recall specific details and relive the past tends to decline with age. To address this, a smartphone application called HippoCamera was developed to help older adults enhance their episodic memory. By repeatedly reactivating memories of real-world events, participants experienced improved recollection and more positive emotions. These benefits were observed shortly after the intervention and even after a 3-month delay.

Summary: Recollection of personal past, or autobiographical memory (AM), varies across individuals and the life span, and is associated with functional brain networks. Older adults showed lower connectivity within certain brain regions but greater connectivity with the default network compared to younger adults. The connectivity patterns were related to specific types of memories.

Summary: This study examines the consistency of brain responses to videos across different data acquisition sites in functional magnetic resonance imaging (fMRI). The results show that video-evoked brain responses have high consistency across different sites, which has implications for studying individual differences in healthy and clinical populations.

Summary: Anxiety disorders are prevalent and disabling, but can be effectively studied using translational neuroscience methodologies. The ENIGMA-Anxiety Working Group aims to address the limitations of small sample sizes and heterogenous imaging methodology in anxiety disorders research, and generate more reliable and reproducible findings. The group has created a harmonized and coordinated effort to study different subtypes of anxiety disorders using neuroimaging data.

Summary: This study addresses the issue of noise in fMRI scans by introducing a dynamic phantom, comparing ground-truth time-series with fMRI data, and introducing new data-quality metrics. By training a convolutional neural network, researchers were able to effectively remove scanner-induced noise, improving the sensitivity of resting-state networks.

Summary: This study presents an MRI-compatible nicotine delivery system to model nicotine addiction as a control system. They establish the viability of this delivery method for studying the brain's response to nicotine addiction and demonstrate its potential application in reliably identifying neuromodulatory targets for pharmacotherapy or brain stimulation. The method enables the measurement of neural circuit responses to drug doses on a single-subject level, aiding the development of data-driven predictive models for addiction research.

Summary: This study analyzed neuroimaging and cognitive data from a large cohort of individuals with type 2 diabetes mellitus (T2DM) and healthy controls. The findings show that T2DM is associated with significant cognitive deficits and structural and functional brain changes, with overlap with aging effects. The duration of the disease is linked to more severe neurodegeneration. Treatment with metformin does not improve neurocognitive outcomes.

Summary: This study found that administration of the ketone d-beta-hydroxybutyrate significantly reduced levels of GABA and Glu in the anterior and posterior cortices of fasting healthy participants. The effect was specific to the ketone and not observed with glucose administration. Furthermore, the magnitude of the effect was greater in older age and correlated with blood levels of the ketone. This suggests an increased sensitivity to ketones in the aging brain.

Summary: Through targeted attacks on the brain network, we found that increasing white matter tract lengths and densities had consistent effects on global communication, regardless of aging and disease. By reversing the attack computation, we derived an analytical equation that explains the brain development mechanism.
