Neurology, 2011
Over the past half-century, insights from research have repeatedly rekindled our curiosity about how the structure of the brain relates to the process of thinking. For example, we now appreciate the importance of the synaptic connections that fill the pink stuff we used to call “neuropil” on brain histologic sections1 and the role of selective neuronal

Brain death is a condition widely recognized by philosophers, theologians, the public, and the law. Criteria for the determination of brain death have been progressively refined for almost 30 years. They involve clinical evidence of the loss of brain function and various periods of observation, which can often be shortened by confirmatory tests ...

Brain microbleeds are small dot-like lesions appearing as hyposignal on gradient echo T2* MR sequences. They represent microscopic areas of old haemosiderin deposits. They are frequent in the setting of symptomatic cerebrovascular disease and also in older healthy people, suggesting a link with cerebral amyloid angiopathy.

Annual Review of Neuroscience, 2006
Functional brain imaging with positron emission tomography and magnetic resonance imaging has been used extensively to map regional changes in brain activity. The signal used by both techniques is based on changes in local circulation and metabolism (brain work).

Brain metastases are the most common intracranial tumors and affect 20% to 30% of patients with systemic cancer. Improvements in diagnostic imaging and recent advances in treatment have resulted in extension of survival and decreased morbidity due to neurologic causes.

Journal of Child Neurology, 2012
For the past 50 years, the medical profession has understood ‘‘brain death’’ to represent the endpoint of a neuropathologic vicious cycle. An initial major brain injury sets off a mutually exacerbating cascade of cerebral edema, increased intracranial pressure, and decreased cerebral blood flow, which advances beyond some point-of-no-return to a state ...

Brain drain, brain gain and brain circulation
Globalisation, Societies and Education, 2006The term ‘brain drain’, popularised in the 1950s with reference to immigration to the United States, has, in the past 10 years, become an important if not controversial political and economic issue...
