The functional hierarchy of the task-positive networks indicates a core control system of top-down regulation in visual attention.

open access: yesJournal of Integrative Neuroscience, 2021
The cingulo-opercular network (CON), dorsal attention network (DAN), and ventral attention network (VAN) are prominently activated during attention tasks.

Principle of Chirality Hierarchy in Three-Blade Propeller Systems [PDF]

open access: yes, 2021
There are different kinds of molecular chirality, such as zero-dimensional point chirality, one-dimensional axial chirality, 2D planar chirality, and 3D chirality.

Systematically disrupted functional gradient of the cortical connectome in generalized epilepsy: Initial discovery and independent sample replication

open access: yesNeuroImage, 2021
Genetic generalized epilepsy is a network disorder typically involving distributed areas identified by classical neuroanatomy. However, the finer topological relationships in terms of continuous spatial arrangement between these systems are still ...

A hierarchy of functional states in working memory [PDF]

open access: yesThe Journal of Neuroscience, 2020
Abstract Extensive research has examined how information is maintained in working memory (WM), but it remains unknown how WM is used to guide behaviour. We addressed this question by combining human electrophysiology with pattern analyses, cognitive modelling, and a task requiring maintenance of two WM items and priority shifts between ...

Functional connectivity development along the sensorimotor-association axis enhances the cortical hierarchy

open access: yesbioRxiv, 2023
Human cortical maturation has been posited to be organized along the sensorimotor-association (S-A) axis, a hierarchical axis of brain organization that spans from unimodal sensorimotor cortices to transmodal association cortices.

Hierarchy of RNA Functional Dynamics [PDF]

open access: yesAnnual Review of Biochemistry, 2014
RNA dynamics play a fundamental role in many cellular functions. However, there is no general framework to describe these complex processes, which typically consist of many structural maneuvers that occur over timescales ranging from picoseconds to seconds.

Colinearity and functional hierarchy among genes of the homeotic complexes.

open access: yesTrends in Genetics, 1994
Homeotic genes identify structures along the anterior to posterior axis during the development of most animals. These genes are clustered into complexes, and their positions within the cluster correlates with their time of expression and the positions of

Functional Connectome Hierarchy in Schizotypy and Its Associations With Expression of Schizophrenia-Related Genes.

open access: yesSchizophrenia bulletin, 2023
BACKGROUND AND HYPOTHESIS Schizotypy has been conceptualized as a continuum of symptoms with marked genetic, neurobiological, and sensory-cognitive overlaps to schizophrenia.

Hierarchy of the Selberg Zeta Functions [PDF]

open access: yesLetters in Mathematical Physics, 2005
We introduce a Selberg type zeta function of two variables which interpolates several higher Selberg zeta functions. The analytic continuation, the functional equation and the determinant expression of this function via the Laplacian on a Riemann surface are obtained.
