[Dynamics of local cerebral blood flow after thermodestruction of the thalamus in the dog].
The dynamics of changes in local cerebral blood flow (LCBF) after stereotaxic thermodestruction of the right thalamus was studied by the method of hydrogen clearance. The experiments were conducted on 22 mongrel dogs. On the 10-12th day after implantation of platinum electrodes the initial values of LCBF were determined symmetrically in the thalami and frontal cortex of dogs who were awake. The animals were anesthetized, the initial values of LCBF were again determined, and destruction of the right thalamus was performed. Reactive hyperemia developed close to the focus of thermodestruction and persisted 90 minutes. In the remaining sites the reactive hyperemia was less manifest and was seen 10-15 minutes.
