Divergent disruption of brain networks following total and chronic sleep loss: a longitudinal fMRI study

This study compares the effects of total sleep deprivation and chronic sleep restriction on brain network organization using fMRI and finds they alter functional connectivity differently.

Circadian rhythm distinctness predicts academic performance based on large-scale learning management system data

This study links circadian rhythm distinctness to academic performance using login data, finding moderate rhythmicity correlates with highest performance and varying effects by chronotype.

Circadian rhythmicity and reinforcement processing: a dataset of MRI, fMRI, and behavioral measurements

The paper presents a dataset combining MRI, fMRI, and behavioral measurements to study circadian rhythmicity and its relationship with reinforcement processing.

High distinctness of circadian rhythm is related to negative emotionality and enhanced neural processing of punishment-related information in men

This study links circadian rhythm distinctness to neural processing of punishment and traits like negative emotionality in men.

The subjective amplitude of the diurnal rhythm matters - chronobiological insights for neuroimaging studies

This study examines how the amplitude of diurnal rhythms relates to brain structure in individuals with different chronotypes, finding correlations in the visual cortex and middle temporal gyrus.

Parcellation of the human amygdala using recurrence quantification analysis

This paper develops a new parcellation method for the human amygdala using resting-state fMRI and recurrence quantification analysis, revealing two subdivisions with distinct functional connectivity patterns.
