Abstract
Unilateral cerebral ischaemia was induced in 18-month-old Long-Evans rats by injection of 2,000 labelled microspheres (phi 50 microns) into the carotid blood stream. This results in an ipsilateral decrease in cerebral blood flow, development of severe oedema and modifications of glucose uptake and consumption. Furthermore, this ischaemia led to a deterioration of the avoidance response in conditioned animals. All these disturbances, including the cerebral oedema, diminished with nicergoline pretreatment.
