Toward the neurovascular unit. A journey in clinical translation: 2012 Thomas Willis Lecture.

The Nobel laureate Max Delbrück often said that it is the crossover between disciplines where advances are possible in science. This certainly has been true for our understanding of the vascular biology of the central nervous system in the setting of ischemic stroke. The ability to cross the boundaries of hemostasis, neurology, hematology, and neuroscience has facilitated our research direction to define the relation of the microvasculature to neuron function. Work begun with the clinical scientific exploration of the contributions of arterial thrombosis to the acute injury processes initiated by focal cerebral ischemia has led to an increased understanding of the effects of ischemia on microvessel integrity.
