The control of global brain dynamics: opposing actions of frontoparietal control and default mode networks on attention [PDF]

, 2013
Understanding how dynamic changes in brain activity control behavior is a major challenge of cognitive neuroscience. Here, we consider the brain as a complex dynamic system and define two measures of brain dynamics: the synchrony of brain activity ...

Predicting intrinsic brain activity

NeuroImage, 2013
Multivariate supervised learning methods exhibit a remarkable ability to decode externally driven sensory, behavioral, and cognitive states from functional neuroimaging data. Although they are typically applied to task-based analyses, supervised learning methods are equally applicable to intrinsic effective and functional connectivity analyses.

Brain mechanisms of mental processing: from evoked and spontaneous brain activities to enactive brain activity

Psychoradiology, 2023
Abstract Within the context of the computer metaphor, evoked brain activity acts as a primary carrier for the brain mechanisms of mental processing. However, many studies have found that evoked brain activity is not the major part of brain activity.

Current Opinion on the Use of c-Fos in Neuroscience

NeuroSci, 2022
For years, the biochemical processes that are triggered by harmful and non-harmful stimuli at the central nervous system level have been extensively studied by the scientific community through numerous techniques and animal models.

Impulsivity and self-control during intertemporal decision making linked to the neural dynamics of reward value representation [PDF]

, 2013
A characteristic marker of impulsive decision making is the discounting of delayed rewards, demonstrated via choice preferences and choice-related brain activity.

Fueling and Imaging Brain Activation [PDF]

ASN Neuro, 2012
Metabolic signals are used for imaging and spectroscopic studies of brain function and disease and to elucidate the cellular basis of neuroenergetics. The major fuel for activated neurons and the models for neuron-astrocyte interactions have been controversial because discordant results are obtained in different experimental systems, some of which do ...

24-hour movement behaviours are cross-sectionally associated with cognitive function in healthy adults aged 55 years and older

Scientific Reports
Global life expectancy has consistently increased since 1950, resulting in more people living to an older age. However, maintaining optimal cognitive health is a challenge as ageing is accompanied by natural cognitive decline, which can affect daily ...
