Detection of Resting-State Functional Connectivity from High-Density Electroencephalography Data: Impact of Head Modeling Strategies

open access: yesBrain Sciences, 2021
Recent technological advances have been permitted to use high-density electroencephalography (hdEEG) for the estimation of functional connectivity and the mapping of resting-state networks (RSNs).

Single prazosin infusion in prelimbic cortex Fosters extinction of amphetamine-induced conditioned place preference [PDF]

open access: yes, 2017
Exposure to drug-associated cues to induce extinction is a useful strategy to contrast cue-induced drug seeking. Norepinephrine (NE) transmission in medial prefrontal cortex has a role in the acquisition and extinction of conditioned place preference ...

Signaling pathways linking behavior to neurogenesis in healthy brain and disease [PDF]

open access: yes, 2020
Self-repair of the adult brain is limited – most diseases lack effective therapy. In order to better understand how a regenerative response can be achieved, studying mechanisms shaping the neurogenic niche, from environmental factors to intrinsic ...

Context value updating and multidimensional neuronal encoding in the retrosplenial cortex

open access: yesNature Communications, 2021
Goal-directed behaviors require the brain to integrate information across many task-related dimensions. Here, the authors use a virtual context discrimination paradigm in mice to demonstrate the capacity for neurons in the retrosplenial cortex to exhibit

Aging-Associated Changes in Cognition, Expression and Epigenetic Regulation of Chondroitin 6-Sulfotransferase Chst3

open access: yesCells, 2022
Understanding changes in the expression of genes involved in regulating various components of the neural extracellular matrix (ECM) during aging can provide an insight into aging-associated decline in synaptic and cognitive functions.

The interaction between endogenous GABA, functional connectivity, and behavioral flexibility is critically altered with advanced age

open access: yesCommunications Biology, 2022
An integrated analysis of GABA concentration, interhemispheric phase-based connectivity behavior and in healthy human participants revealed a task-specific association between GABA concentration and motor-cortical connectivity.

Heparan Sulfates Regulate Axonal Excitability and Context Generalization through Ca2+/Calmodulin-Dependent Protein Kinase II

open access: yesCells, 2023
Our previous studies demonstrated that enzymatic removal of highly sulfated heparan sulfates with heparinase 1 impaired axonal excitability and reduced expression of ankyrin G at the axon initial segments in the CA1 region of the hippocampus ex vivo ...

Astrogliosis and sexually dimorphic neurodegeneration and microgliosis in the olfactory bulb in Parkinson’s disease

open access: yesnpj Parkinson's Disease, 2021
Hyposmia is prodromal, and male sex is a risk marker for an enhanced likelihood ratio of Parkinson’s disease. The literature regarding olfactory bulb volume reduction is controversial, although the olfactory bulb has been largely reported as an early and

State and trait of finger tapping performance in multiple sclerosis

open access: yesScientific Reports, 2021
Finger tapping tests have been shown feasible to assess motor performance in multiple sclerosis (MS) and were observed to be strongly associated with the estimated clinical severity of the disease.
