The intratemporal portion of the facial nerve has a single bundle, while the extratemporal portion has multiple funiculi. In the guinea pig, the funiculi repeatedly divide and fuse between the stylomastoid foramen and the origin of the inferior labial branch. It remains unknown whether the nerve fibers in each funiculus are topographically organized or not. In this paper, the topographic organi...

BACKGROUND Abnormal connectivity across brain regions underlies many neurological disorders including multiple sclerosis, schizophrenia and autism, possibly due to atypical axonal organization within white matter. Attempts at investigating axonal organization on post-mortem human brains have been hindered by the availability of high-quality, morphologically preserved tissue, particularly for ne...

Cerebellar disorders characterized by degeneration or loss of Purkinje cells have been reported in many In the dog, they have occurred in Airedales,' Gordon setters,*z4 rough coated collies,6 border collie^,^ beagle^,^ Sam~yeds ,~ and Irish setters.'O An 18-month-old female and a 9-month-old male were mated in our beagle colony. The female was purchased from Marshall Farms, North Rose, New York...

Regional Cerebral Blood Flow During Stimulation of Seventh Cranial Nerve • The right seventh cranial nerve (n. VII) was exposed intracranially via a suboccipital approach in each of eight cats. Measurements of cerebral blood flow (CBF) were made from superficial cortex, sulcal cortex, basal cortex, the basal ganglia, and the centrum semiovale of each cerebral hemisphere of each cat by autoradio...

The stock of Os mice studied was maintained in the Department of Animal Genetics, University College London. During the later part of the work, a colony was established at New York University Medical Center from mice kindly sent by Professor Griineberg. Embryos from Os/+ xOs/ + and from Osj + x +1+ matings were examined between the 3rd and 8th day of gestation. Age was determined by the standar...

The subscapularis tendon, coracohumeral ligament, and transverse humeral ligament are all believed to contribute to biceps tendon stability within the bicipital groove. In order to examine the relative contribution of these soft tissue structures to proximal biceps tendon stability, 11 fresh frozen cadaveric shoulder specimens were prepared and mounted onto a custom jig. A three-dimensional dig...
