Task-evoked deactivations: dissociation between BOLD fMRI and FDG

The paper investigates task-evoked BOLD fMRI deactivations and finds that they do not correlate with decreased glucose consumption, suggesting metabolic stability or increase in these regions.

Parallel processing chains span cytoarchitectures to organize association cortex

The paper identifies parallel processing chains in association cortex using multiple functional mapping modalities, showing they are experience-driven and organized across different cytoarchitectures.

Stimulant medications affect arousal and reward, not attention

This study shows stimulant medications affect brain connectivity in action/motor and reward-related regions, not attention networks, and mimic the effects of sleep.

Arousal as a universal embedding for spatiotemporal brain dynamics

The paper demonstrates that a single arousal measurement can reconstruct spatiotemporal brain dynamics across multiple modalities in awake mice.

Hyperglycemia selectively increases cerebral non-oxidative glucose consumption without affecting blood flow

The paper shows acute hyperglycemia increases non-oxidative glucose consumption in specific brain regions without altering cerebral blood flow or oxygen metabolism.

Disuse-driven plasticity in the human thalamus and putamen

This study investigates disuse-driven plasticity in the human thalamus and putamen using fMRI, finding strengthened functional connectivity and signal pulses in these regions during limb immobilization.

The brainstem's red nucleus was evolutionarily upgraded to support goal-directed action

The paper examines the functional connectivity of the human red nucleus using resting-state fMRI and finds it is involved in goal-directed behavior and cognitive control rather than motor function.

Brain aerobic glycolysis and resilience in Alzheimer disease

This study finds that preserved aerobic glycolysis in the brain is linked to resilience against Alzheimer's disease pathology, while white matter hyperintensity burden is associated with reduced youthful AG patterns.

A mind-body interface alternates with effector-specific regions in motor cortex

The paper reveals that motor cortex contains inter-effector regions connected to the Cingulo-opercular network, alternating with effector-specific areas, suggesting a dual system for motor control and whole-body coordination.

Acute hyper- and hypoglycemia uncouples the metabolic cooperation between glucose and lactate to disrupt sleep

This study shows that acute hyper- and hypoglycemia disrupt the metabolic cooperation between glucose and lactate in the brain, affecting sleep-wake cycles.

The Role of the Human Brain Neuron-Glia-Synaptic Composition in Forming Resting State Functional Connectivity Networks

The paper investigates how brain cellular composition relates to resting state functional connectivity networks using MRI data.

Parallel Hippocampal-Parietal Circuits for Self- and Goal-oriented Processing

The paper identifies distinct functional connectivity patterns in the hippocampus, showing anterior regions connect to the default mode network and posterior regions connect to the parietal memory network, supporting different cognitive processes.

Cingulo-Opercular Control Network Supports Disused Motor Circuits in Standby Mode

The paper shows that disused motor regions become more connected to the cingulo-opercular network during limb constraint, mediated by spontaneous activity pulses.
