This study introduces a neuroimaging framework to discover state-dependent signal flow hierarchy in the human cerebral cortex using integrated effective connectivity and signal flow mapping.

The paper introduces SCD to analyze spatial influences on cortical functional specialization, revealing a dominant gradient and competitive suppression from other brain regions.

The paper compares distractibility between marmosets and macaques in cognitive tasks and links it to dopamine D1 receptor expression in prefrontal parvalbumin neurons.

This study identifies three cortical streams for somatosensory information processing in macaques by integrating receptor covariance and connectivity data.

This study benchmarks macaque brain gene expression for horizontal and vertical translation by comparing it to human gene expression and protein density.

This study examines how psilocybin affects neural network dynamics in rat prefrontal cortex over time, finding increased beta and low-gamma power in infralimbic cortex days after administration.

The paper develops a model of neocortex-wide neural activity to explain cognitive network interactions and dynamic routing during cognition.

This study creates normative brain growth charts for rhesus macaques across their lifespan using MRI data, revealing developmental milestones and cross-species comparisons with humans.

The paper develops a large-scale mouse brain model to predict working memory activity, showing distributed and modular coding based on cell type-specific connectome features.

The paper identifies 35 prefrontal areas in macaques, reveals regional receptor differences, and shows functional connectivity patterns across clusters of frontal lobe areas.

This paper develops a mesoscale connectome-based model of the macaque cortex to simulate conscious access, showing how receptor dynamics drive ignition-like events in neural networks.

This study trains mice to perform a delayed gratification task and shows that VTA dopamine neuron activity increases during waiting, with reinforcement learning modeling supporting the role of sustained dopaminergic signals in delaying gratification.

This study shows that a dopamine gradient in monkey cortex influences working memory by filtering stimuli and determining memory encoding mechanisms.

The paper creates a 3D atlas of the macaque motor and premotor cortex by integrating cytoarchitectonic and receptor data, revealing 16 distinct areas and their functional connectivity patterns.

This study examines altered cortical gyrification in very preterm adults and its links to cognitive and mental health outcomes.

The paper examines individual differences in functional connectivity in awake and anesthetized rhesus monkeys using fMRI datasets, finding distinct variability patterns under different states.

This study shows that hippocampal lesions in rhesus monkeys impair scene memory retrieval but not new learning, suggesting the hippocampus is critical for recalling past memories but not forming new ones.

This study assesses psychiatric symptomatology in adults born very preterm using a dimensional approach and finds elevated symptoms and a non-specific psychopathology profile.

This study finds that perinatal brain injury in very preterm humans is linked to reduced dopamine synthesis and hippocampal volume in adulthood.

This study identifies volumetric grey matter changes in very preterm individuals from adolescence to adulthood, showing accelerated brain maturation and regional vulnerability.
