This study examines how cortical asymmetry and its developmental changes relate to brain connectivity across three cohorts from birth to 22 years.

The paper evaluates the reproducibility of diffusion, shape, and connectivity metrics across scanners in multi-site tractography studies and finds shape metrics show the highest reproducibility.

The paper develops a hierarchical atlas for gray-matter parcellation across multiple species, validated through cross-species comparisons and connectivity analysis.

The paper constructs directed connectomes across species using viral tracing and diffusion MRI to identify conserved and divergent neural pathways.

This study uses MRI metrics to identify microstructural differences in myelin and axons between ASD and neurotypical adolescents, finding increased extracellular water and decreased g-ratio and conduction velocity.

This study shows that metastable dynamics in cortical networks arise from interactions between excitatory and inhibitory neurons, and introduces a metric to analyze these transitions.

The paper shows that networks of identical bursting neurons with inhibitory coupling exhibit itinerant dynamics and transient synchrony modes, unlike singlet-spiking neurons.

The paper classifies firing patterns of hippocampal neuron types using automated protocols and identifies new subtypes and statistical associations between firing patterns and other properties.

The paper develops simple models of hippocampal neuron firing patterns to capture intrinsic diversity and maps 120 neuron types to a low-dimensional model space.
