Meta-Potentiation: Neuro-Astroglial Interactions Supporting Perceptual Consciousness [PDF]

, 2007
Conscious perceptual processing involves the sequential activation of cortical networks at several brain locations, and the onset of oscillatory synchrony affecting the same neuronal population.

A blind deconvolution approach to recover effective connectivity brain networks from resting state fMRI data

, 2012
A great improvement to the insight on brain function that we can get from fMRI data can come from effective connectivity analysis, in which the flow of information between even remote brain regions is inferred by the parameters of a predictive dynamical ...

Complex hemodynamic responses to trans-vascular electrical stimulation of the renal nerve in anesthetized pigs [PDF]

arXiv
The objective of this study was to characterize hemodynamic changes during trans-vascular stimulation of the renal nerve and their dependence on stimulation parameters. We employed a stimulation catheter inserted in the right renal artery under fluoroscopic guidance, in pigs.

Aberrant activity in conceptual networks underlies N400 deficits and unusual thoughts in schizophrenia. [PDF]

, 2019
BackgroundThe N400 event-related potential (ERP) is triggered by meaningful stimuli that are incongruous, or unmatched, with their semantic context. Functional magnetic resonance imaging (fMRI) studies have identified brain regions activated by semantic ...

A Coupled Diffusion Approximation for Spatiotemporal Hemodynamic Response and Deoxygenated Blood Volume Fraction in Microcirculation [PDF]

arXiv
Background and Objective: This proof of concept study investigates mathematical modelling of blood flow and oxygen transport in cerebral microcirculation, focusing on understanding hemodynamic responses. By coupling oxygen transport models and blood flow dynamics, the research aims to predict spatiotemporal hemodynamic responses and their impact on ...

Event-related functional magnetic resonance imaging of reward-related brain circuitry in children and adolescents [PDF]

, 2007
BACKGROUND: Functional disturbances in reward-related brain systems are thought to play a role in the development of mood, impulse, and substance abuse disorders. Studies in non-human primates have identified brain regions, including the dorsal / ventral
