The cellular pathology of Purkinje cells in several degenerative diseases of the cerebellum and its connections was studied with the rapid Golgi method. Purkinje cells from a patient with Creutzfeldt-Jakob disease (case 1) showed decreased numbers of spiny branchlets. In a patient with a cystic infarct of the cerebellar white matter and chronic(More)
Multichannel and high-resolution seismic profiles complemented with swath bathymetry show a variety of contourite deposits in the northern Weddell Sea resulting from the interaction between bottom currents and the seafloor physiography. Seven types of contourite drifts are identified based on the seismic signature, reflector configuration and geometry of(More)
A new type of surface coil is described which allows the user to continuously vary the size of the field of view. This utilizes a modified radiofrequency trombone for size adjustment that results in a stable frequency over a wide range of dimensions. Results show that the coil may be increased in area by as much as 60% while maintaining frequency stability(More)
