Microfluidic platforms for probing spontaneous functional recovery in hierarchically modular neuronal networks

This study uses microfluidic platforms to investigate how damage to hub or peripheral connections in modular neuronal networks affects recovery, finding that hub damage leads to delayed recovery through alternative pathway formation.

System identification and surrogate data analyses imply approximate Gaussianity and non-stationarity of resting-brain dynamics

The paper analyzes resting-state fMRI data to determine its statistical properties, finding approximate Gaussianity and non-stationarity, which help distinguish real data from surrogates.

Structure-Function Coupling Aligns with a Unimodal-to-Transmodal Gradient in the Mouse Cortex

The paper maps structure-function coupling in the mouse cortex, finding a unimodal-to-transmodal gradient similar to humans, influenced by cellular properties but not anatomical hierarchy.

Orthogonalization of spontaneous and stimulus-driven activity by hierarchical neocortical areal network in primates

The paper investigates how spontaneous and stimulus-driven activity are orthogonalized in primate visual cortex, finding that this process occurs hierarchically across cortical areas.

Linear models replicate the energy landscape and dynamics of resting-state brain activity

The paper shows that linear models can accurately capture the dynamics of resting-state brain activity, as non-linear methods like ELA produce features similar to stationary, linear surrogate data.

Location analysis of presynaptically active and silent synapses in single-cultured hippocampal neurons

This study examines the distribution and developmental changes of presynaptically active and silent synapses in hippocampal neurons, introducing a new method called donut analysis.

Healthy dietary choices involve prefrontal mechanisms associated with long-term reward maximization but not cognitive control

The paper investigates neural mechanisms of healthy food choice, finding that prefrontal cortex activity correlates with self-control and long-term reward maximization, but not cognitive control.

On co-activation pattern analysis and non-stationarity of resting brain activity

This study shows that coactivation pattern analysis of resting brain fMRI data does not reliably indicate non-stationarity, as results are similar for real data and simulated stationary data.

Executive control by fronto-parietal activity explains counterintuitive decision behavior in complex value-based decision-making

This study examines decision-making in a multifactor gambling task, finding that fronto-parietal cognitive control influences reaction times and strategy switching in complex value-based decisions.

Vision-to-value transformations in artificial neural networks and human brain

This study compares CNNs to human brain activity to show that vision-to-value transformation is hierarchical, mirroring neural pathways from primary visual cortex to transmodal regions.

Astrocytes in the mouse visual cortex reliably respond to visual stimulation

The paper investigates visual responses of astrocytes in the mouse visual cortex and finds they respond with a 5-second delay relative to neurons.

Neuronal origin of the temporal dynamics of spontaneous BOLD activity correlation

The paper investigates the neuronal origin of dynamic functional connectivity by comparing neuronal calcium and hemodynamic signals in mice, showing their coordinated temporal dynamics and the role of transient coactivation patterns.
