Brain connectivity and visual attention. [PDF]

Brain Connectivity, 2023
Emerging hypotheses suggest that efficient cognitive functioning requires the integration of separate, but interconnected cortical networks in the brain. Although task-related measures of brain activity suggest that a frontoparietal network is associated

Dynamic state with covarying brain activity-connectivity: On the pathophysiology of schizophrenia

NeuroImage, 2021
The human brain is a dynamic system that incorporates the evolution of local activities and the reconfiguration of brain interactions. Reoccurring brain patterns, regarded as “brain states”, have revealed new insights into the pathophysiology of brain ...

The Effects of Directional and Non-Directional Stimuli during a Visuomotor Task and Their Correlation with Reaction Time: An ERP Study

Sensors, 2023
Different visual stimuli can capture and shift attention into different directions. Few studies have explored differences in brain response due to directional (DS) and non-directional visual stimuli (nDS). To explore the latter, event-related potentials (

A new open, high-resolution, multishell, diffusion-weighted imaging dataset of the living squirrel monkey

Scientific Data, 2023
Although very well adapted to brain study, Magnetic Resonance Imaging (MRI) remains limited by the facilities and capabilities required to acquire data, especially for non-human primates. Addressing the data gaps resulting from these limitations requires

Transcriptional and morphological profiling of parvalbumin interneuron subpopulations in the mouse hippocampus

Nature Communications, 2021
The relationship between gene expression and morphology to classify PV interneurons is unclear. Here, the authors show transcriptional continuity of morphologically distinct mouse hippocampal PV interneurons subtypes, combining single-cell RNA sequencing

Discovering Microcircuit Secrets With Multi-Spot Imaging and Electrophysiological Recordings: The Example of Cerebellar Network Dynamics

Frontiers in Cellular Neuroscience, 2022
The cerebellar cortex microcircuit is characterized by a highly ordered neuronal architecture having a relatively simple and stereotyped connectivity pattern.

Anisotropy and Frequency Dependence of Signal Propagation in the Cerebellar Circuit Revealed by High-Density Multielectrode Array Recordings

Biomedicines, 2023
The cerebellum is one of the most connected structures of the central nervous system and receives inputs over an extended frequency range. Nevertheless, the frequency dependence of cerebellar cortical processing remains elusive.

Graph Theory on Brain Cortical Sources in Parkinson’s Disease: The Analysis of ‘Small World’ Organization from EEG

Sensors, 2021
Parkinson’s disease (PD) is the second most common neurodegenerative disease in the elderly population. Similarly to other neurodegenerative diseases, the early diagnosis of PD is quite difficult.

Brain Connectivity and Graph Theory Analysis in Alzheimer’s and Parkinson’s Disease: The Contribution of Electrophysiological Techniques

Brain Sciences, 2022
In recent years, applications of the network science to electrophysiological data have increased as electrophysiological techniques are not only relatively low cost, largely available on the territory and non-invasive, but also potential tools for large ...

Linking spontaneous and stimulated spine dynamics

Communications Biology, 2023
Our brains continuously acquire and store memories through synaptic plasticity. However, spontaneous synaptic changes can also occur and pose a challenge for maintaining stable memories.
