Incentive valence differentially engages open- and closed-loop basal ganglia circuits during movement initiation

The paper investigates how incentive valence engages different basal ganglia circuits during movement initiation, finding distinct neural patterns for reward and threat conditions.

A recurrent neural network model of chronic pain development and recovery

The paper develops a recurrent neural network model to explain chronic pain development and recovery, showing that calming stimuli can reduce pain without pharmacological intervention.

Neurobiological Signatures of Endometriosis: Characterizing Pain, Cognition, and Brain Morphology

This study investigates the neurobiological correlates of endometriosis by integrating neuroimaging, biofluids, and cognitive assessments, finding pain-related brain structure and microstructure changes in affected individuals.

No Disconnection Syndrome after Near-Complete Callosotomy

The paper shows that retaining only the splenium of the corpus callosum prevents disconnection syndrome, suggesting minimal pathways can maintain functional unity.

Full inter-hemispheric integration sustained by a fraction of posterior callosal fibers

The paper shows that a small portion of posterior callosal fibers can sustain full inter-hemispheric integration, challenging the traditional topographic model of callosal organization.

Neuroanatomical changes observed over the course of a human pregnancy

This study maps neuroanatomical changes in a human brain from preconception to two years postpartum, revealing decreases in gray matter and increases in white matter integrity.

Diurnal fluctuations in steroid hormones tied to variation in intrinsic functional connectivity in a densely sampled male

The paper examines diurnal hormone fluctuations and their link to brain functional connectivity in a man, finding positive associations between testosterone, cortisol, and estradiol with whole-brain coherence.

High-amplitude network co-fluctuations linked to variation in hormone concentrations over menstrual cycle

The paper examines how hormonal fluctuations during the menstrual cycle affect brain network states using edge time series analysis in a single individual.

Dynamic cerebellar network organization across the human menstrual cycle

This study examines how sex steroid hormones affect cerebellar network dynamics across the menstrual cycle using resting-state functional connectivity.

Dynamic community detection reveals transient reorganization of functional brain networks across a female menstrual cycle

The paper uses dynamic community detection to analyze brain imaging data from a female over her menstrual cycle, revealing transient reorganization of functional brain networks during ovulation.

Progesterone shapes medial temporal lobe volume across the human menstrual cycle

This study investigates how progesterone fluctuations affect medial temporal lobe volume in humans across the menstrual cycle and finds that progesterone dynamically shapes this volume, with chronic suppression altering these effects.

Functional reorganization of brain networks across the human menstrual cycle

This study shows how sex hormones like estrogen and progesterone influence brain network dynamics across the menstrual cycle, with estrogen promoting network coherence and progesterone reducing it, particularly in hormone-sensitive hubs.
