Structural subnetwork evolution across the life-span: rich-club, feeder, seeder

open access: yes, 2018
The impact of developmental and aging processes on brain connectivity and the connectome has been widely studied. Network theoretical measures and certain topological principles are computed from the entire brain, however there is a need to separate and ...

The topology of large Open Connectome networks for the human brain [PDF]

open access: yes, 2016
The structural human connectome (i.e.\ the network of fiber connections in the brain) can be analyzed at ever finer spatial resolution thanks to advances in neuroimaging.

Olfactory‐to‐Entorhinal Network Dysrhythmias Drive Parkinson's Cognitive Impairment Through Frequency‐Specific Oscillatory Decoupling

open access: yesAdvanced Science, EarlyView.
Wang et al reveal that in the olfactory system, the selective impairment of gamma‐driven Barcode features underlying early olfactory deficits, while the selective impairment of theta‐driven Barcode features underlying later cognitive deficits, further establishing cross‐network gamma oscillations in the early stage as a biomarker of later cognitive ...

Osteocalcin Alleviates Lipopolysaccharide-Induced Acute Inflammation via Activation of GPR37 in Macrophages

open access: yesBiomedicines, 2022
The G protein-coupled receptor 37 (GPR37) has been reported to be expressed in macrophages and the activation of GPR37 by its ligand/agonist, and it can regulate macrophage-associated functions and inflammatory responses.

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

open access: yesAdvanced Science, EarlyView.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Development of Cre-dependent retrograde trans-multisynaptic tracer based on pseudorabies virus bartha strain

open access: yesMolecular Brain
Mapping the neural circuit of a specific neuronal subclass is central to understanding the working mechanism of the brain. Currently, numerous types of transgenic mice expressing Cre recombinase have been engineered and widely used in neuroscience.

Mapping the rest of the human connectome: Atlasing the spinal cord and peripheral nervous system

open access: yesNeuroImage, 2021
The emergence of diffusion, structural, and functional neuroimaging methods has enabled major multi-site efforts to map the human connectome, which has heretofore been defined as containing all neural connections in the central nervous system (CNS ...

Decoupling of brain function from structure reveals regional behavioral specialization in humans

open access: yes, 2019
The brain is an assembly of neuronal populations interconnected by structural pathways. Brain activity is expressed on and constrained by this substrate.

Data leakage inflates prediction performance in connectome-based machine learning models

open access: yesNature Communications
Predictive modeling is a central technique in neuroimaging to identify brain-behavior relationships and test their generalizability to unseen data. However, data leakage undermines the validity of predictive models by breaching the separation between ...
