Neurovascular Radiosurgery

The Bimodal Nature of Neurovascular Coupling

Neurons, by virtue of their complex and continuously changing signaling roles in brain, must be able to regulate access to energy in order to maintain their ability to communicate meaningful frequency-encoded information. This is accomplished by release of neurotransmitters to astrocytes that in turn signal the vascular system to increase cerebral blood flow (CBF). This process has been termed ...

but also well-controlled manipulations (Allegra Mascaro et al., 2010; Kleinfeld et al., 2011) crucial for testing causality rather than simply establishing a correlation between measurement parameters (that does not automatically imply that one of the parameters drives the other). Moreover, the present collection of papers reaches well beyond the current state of knowledge, defining important q...

Stereotactic Radiosurgery/Radiotherapy: A Historical Review

"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...

Stereotactic radiosurgery.

The development and scope of stereotactic radiosurgery is described. The technique, which combines well with the latest diagnostic methods, has already proved a safe and effective way of treating inaccessible cerebral lesions and in particular small arteriovenous malformations, acoustic neuroma and the solid component of craniopharyngioma, as well as playing an increasingly useful role in the t...
