The properties of the fast Na inward current of the aminergic neurosecretory dorsal unpaired median (DUM) cells isolated from the sixth abdominal ganglion of the cockroach Periplaneta americana were studied with the whole-cell clamp technique in the presence of Ca and K channel blockers. In about 80 % of the cells, the current activated at -35 mV, was maximal at lOmV and reversed at +48mV (Vrev...

Rohit R. Saboo: Atlas Diffeomorphisms via Object Models (Late Draft). (Under the direction of Stephen M. Pizer.) To tackle the problem of segmenting several closely-spaced objects from 3D medical images, I propose a hybrid of two segmentation approaches: one image-based and one modelbased. A major contribution takes the image-based approach by diffeomorphically mapping a fully segmented atlas i...
