The discrete anatomical localization of vagal aortic afferents within a catecholamine-containing cell group in the nucleus solitarius.

The centripetal transport of horseradish peroxidase (HRP) was used to visualize the central projections of afferent fibers of the aortic arch nerve to the nucleus solitarius in pigeons. Our results indicate that aortic nerve afferents have a restricted distribution within one subdivision of the nucleus solitarius, designated the subnucleus sulcalis dorsalis. Histofluorescence studies revealed that the aortic nerve projection area is extremely rich in catecholamine-containing neurons.

Doppler sonography diagnosis of cerebrovascular disease.

Sonographic patterns for the Doppler ophthalmic test (DOT) were determined by reviewing the type of graphic record obtained from 25 patients who had undergone angiography. Three principal patterns were identified, depending upon whether there was augmentation (Type 1), diminution (Type 2) or no change (Type 3) in the character of the supraorbital Doppler signal upon temporal artery compression. Type 1 records were seen in 28 of 33 instances where the carotid arteries remained patent. Type 2 records occurred in 10 of 14 instances where there was significant carotid stenoses or tortuosity and in two instances in a patient with a subclavian steal syndrome. A "false-positive" test was recorded in one instance in a patient with vascular headaches. There were three Type 3 records.
