Blood flow in the brain is regulated by neurons and astrocytes. Knowledge of how these
cells control blood flow is crucial for understanding how neural computation is powered, for …

The past 15years has seen a rapid expansion in the number of studies using neuroimaging
techniques to investigate maturational changes in the human brain. In this paper, I review …

The term'social brain'refers to the network of brain regions that are involved in
understanding others. Behaviour that is related to social cognition changes dramatically …

The concept of a default mode of brain function arose out of a focused need to explain the
appearance of activity decreases in functional neuroimaging data when the control state …

Despite a rapidly-growing scientific and clinical brain imaging literature based on functional
magnetic resonance imaging (fMRI) using blood oxygenation level-dependent (BOLD) …

Functional brain imaging with positron emission tomography and magnetic resonance
imaging has been used extensively to map regional changes in brain activity. The signal …

The brain is a heterogeneous organ with regionally varied and constantly changing
energetic needs. Blood vessels in the brain are equipped with control mechanisms that …

Local increase in blood flow during neural activity forms the basis for functional brain
imaging, but its mechanism remains poorly defined. Here we show that cortical astrocytes in …

Deep brain stimulation (DBS) has shown remarkable therapeutic benefits for patients with
otherwise treatment-resistant movement and affective disorders. This technique is not only …

Neural activity is intimately tied to blood flow in the brain. This coupling is specific enough in
space and time that modern imaging methods use local hemodynamics as a measure of …
