Functional magnetic resonance imaging (fMRI) provides a unique view of the working
human mind. The blood-oxygen-level-dependent (BOLD) signal, detected in fMRI, reflects …

Although modern techniques such as two-photon microscopy can now provide cellular-level
three-dimensional imaging of the intact living brain, the speed and fields of view of these …

Optical brain imaging has seen 30 years of intense development, and has grown into a rich
and diverse field. In-vivo imaging using light provides unprecedented sensitivity to functional …

Functional magnetic resonance imaging (fMRI) has become the dominant means of
measuring behavior-related neural activity in the human brain. Yet the relation between the …

In the last few years, the notion that the brain has a default or intrinsic mode of functioning
has received increasing attention. The idea derives from observations that a consistent …

Brain aging is characterized by changes in both hemodynamic and neuronal responses,
which may be influenced by the cardiorespiratory fitness of the individual. To investigate the …

Resting-state functional magnetic resonance imaging (rs-fMRI), which measures the
spontaneous fluctuations in the blood oxygen level-dependent (BOLD) signal, is …

The mechanisms that link a transient neural activity to the corresponding increase of
cerebral blood flow (CBF) are termed neurovascular coupling (NVC). They are possibly …

The cortical hemodynamic response to somatosensory stimulus is investigated at the level of
individual vascular compartments using both depth-resolved optical imaging and in-vivo two …

Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) are
important tools in cognitive and clinical neuroscience. Combined EEG–fMRI has been …
