A multi-modal parcellation of human globus pallidus and its implications for symptom prediction and stratification in Parkinson’s disease [PDF]
BMC MedicineBackground The globus pallidus (GP) is a critical basal ganglia nucleus for motor and cognitive control. However, traditional single-modality parcellations provide an incomplete understanding of its internal organization, thereby increasing the risk of ...

Inter-subject and inter-parcellation variability of resting-state whole-brain dynamical modeling
NeuroImage, 2021 Modern approaches to investigate complex brain dynamics suggest to represent the brain as a functional network of brain regions defined by a brain atlas, while edges represent the structural or functional connectivity among them.

Fine-grained functional parcellation maps of the infant cerebral cortex
eLife, 2023 Resting-state functional MRI (rs-fMRI) is widely used to examine the dynamic brain functional development of infants, but these studies typically require precise cortical parcellation maps, which cannot be directly borrowed from adult-based functional ...

Comparison between gradients and parcellations for functional connectivity prediction of behavior
NeuroImage, 2023 Resting-state functional connectivity (RSFC) is widely used to predict behavioral measures. To predict behavioral measures, representing RSFC with parcellations and gradients are the two most popular approaches. Here, we compare parcellation and gradient

The structure of the serotonin system: A PET imaging study
NeuroImage, 2020 The human brain atlas of the serotonin (5-HT) system does not conform with commonly used parcellations of neocortex, since the spatial distribution of homogeneous 5-HT receptors and transporter is not aligned with such brain regions.

Effects of diffusion signal modeling and segmentation approaches on subthalamic nucleus parcellation
NeuroImage, 2022 The subthalamic nucleus (STN) is commonly used as a surgical target for deep brain stimulation in movement disorders such as Parkinson's Disease. Tractography-derived connectivity-based parcellation (CBP) has been recently proposed as a suitable tool for

From Coarse to Fine-Grained Parcellation of the Cortical Surface Using a Fiber-Bundle Atlas
Frontiers in Neuroinformatics, 2020 In this article, we present a hybrid method to create fine-grained parcellations of the cortical surface, from a coarse-grained parcellation according to an anatomical atlas, based on cortico-cortical connectivity.

Parcellation‐based tractographic modeling of the salience network through meta‐analysis
Brain and Behavior, 2022 Background The salience network (SN) is a transitory mediator between active and passive states of mind. Multiple cortical areas, including the opercular, insular, and cingulate cortices have been linked in this processing, though knowledge of network ...
