The paper examines how brain network segregation relates to episodic memory performance across age, finding age-invariant associations between functional connectivity and memory.

The paper investigates hippocampal-neocortical coupling after memory encoding and finds widespread upregulation of functional connectivity during post-encoding rest, suggesting broader reactivation beyond perceptual aspects.

This study shows that 32 hours of sleep deprivation increases the T1w/T2w ratio in specific cortical regions compared to a normal sleep-wake cycle.

This study uses mixed models and advanced diffusion imaging to show that sleep deprivation and normal sleep-wake cycles differentially affect white matter microstructure.
