Electrical perturbation reveals a directional architecture for communication across human visual streams

The paper uses electrical stimulation to map directional connectivity in human visual cortex, revealing an asymmetric architecture of interareal influence.

White matter conduction in the human brain is mostly slow, with rare high velocity connections

The paper measures conduction velocities in human white matter bundles using dMRI tractography and intracranial stimulation, finding high variability and a predominance of slow connections.

Progressive Centro-Parietal ERP Responses During Contextual Integration Across Symbolic Domains

The paper examines ERP responses during contextual integration across symbolic domains and finds progressive, position-related increases in centro-parietal activity, with the strongest increase at the final sequence position.

Human pulvinar stimulation engages select cortical pathways in epilepsy

This study shows that electrical stimulation of different pulvinar subregions in epilepsy patients evokes distinct patterns of brain activity in occipital, parietal, and temporal areas.
