Neural activity in the brain is accompanied by changes in cerebral blood flow (CBF) and
blood oxygenation that are detectable with functional magnetic resonance imaging (fMRI) …

The classical model of blood oxygen level-dependent (BOLD) responses by Buxton et
al.[Buxton, RB, Wong, EC, Frank, LR, 1998. Dynamics of blood flow and oxygenation …

The BOLD contrast mechanism has a complex relationship with functional brain activity,
oxygen metabolism, and neurovascular factors. Accurate interpretation of the BOLD signal …

A biomechanical model is presented for the dynamic changes in deoxyhemoglobin content
during brain activation. The model incorporates the conflicting effects of dynamic changes in …

In functional magnetic resonance imaging (fMRI), modeling the complex link between
neuronal activity and its hemodynamic response via the neurovascular coupling requires an …

This personal recollection looks at the evolution of ideas about the dynamics of the blood
oxygenation level dependent (BOLD) signal, with an emphasis on the balloon model. From …

Functional magnetic resonance imaging (fMRI) is a methodology for detecting dynamic
patterns of activity in the working human brain. Although the initial discoveries that led to …

Our goal is to model the coupling between neuronal activity, cerebral metabolic rates of
glucose and oxygen consumption, cerebral blood flow (CBF), electroencephalography …

A recent nonlinear system by Friston et al.(2000. NeuroImage 12: 466–477) links the
changes in BOLD response to changes in neural activity. The system consists of five …

The linearity of the cerebral perfusion response relative to stimulus duration is an important
consideration in the characterization of the relationship between regional cerebral blood …
