The brain is a complex, multiscale dynamical system composed of many interacting regions.
Knowledge of the spatiotemporal organization of these interactions is critical for establishing …

In the brain, increases in neural activity drive changes in local blood flow via neurovascular
coupling. The common explanation for increased blood flow (known as functional …

Depression is a highly heterogeneous syndrome that bears only modest correlations with its
biological substrates, motivating a renewed interest in rethinking our approach to …

Psychosocial stress is an omnipresent phenomenon whose neural correlates in humans are
still poorly understood. Several paradigms have been developed to induce acute stress in …

The hemodynamic response function (HRF) greatly influences the intra-and inter-subject
variability of brain activation and connectivity, and might confound the estimation of temporal …

Teaching professionals report higher levels of work-related stress and symptoms of
psychological health problems than the general population. This study examined …

Accurate identification of brain function is necessary to understand the neurobiology of
cognitive ageing, and thereby promote well-being across the lifespan. A common tool used …

Typical fMRI analyses often assume a canonical hemodynamic response function (HRF) that
primarily focuses on the peak height of the overshoot, neglecting other morphological …

Animal-fMRI is a powerful method to understand neural mechanisms of cognition, but it
remains a major challenge to scan actively participating small animals under low-stress …
