Functional neuroimaging has confirmed a high degree of localization of function in the cerebral cortex of man. In contrast, microstructural analysis has contributed very little to the topographical characterization of cortical areas. In this work I...
Hematopoietic stem cells (HSCs) balance self-renewal with the continuous production of the suitable numbers of lineage-restricted progenitor cells. In this work we demonstrate that the Mixed lineage leukemia 1 (Mll1) gene is essential for this...

Head Direction (HD) cells are neurons located primarily in the limbic system that fire as a function of directional heading in the horizontal, or yaw, plane in the freely moving animal. Our hypothesis is that the HD signal is the result of two...
The iodothyronine deiodinases, D1, D2, and D3, play a crucial role in determining the circulating and intracellular levels of active and inactive thyroid hormone (TH), and thus have a major effect on TH action during development and adulthood. The...
Elevated sympathetic discharge from the CNS is an underlying pathogenic mechanism in neurogenic hypertension and an exacerbating factor in chronic heart failure (CHF). Current treatment of these diseases focuses on attenuation of the downstream...
The oculomotor system needs up-to-date information about eye position in order to make accurate saccades to stimuli in the environment. This thesis investigated how well the oculomotor system uses information about eye position to make a variety of...
When we want to know what others are thinking or feeling, we look to their face for clues. Affective neuroscience has usefully documented behavioral, psychophysiological and neural responses to the facial displays of others. Though this work...
The rat limbic system contains head direction (HD) cells that fire according to heading in the horizontal plane. These HD cells are thought to provide animals with an internal compass to guide navigation. Previous work has found that HD cell tuning...
Acyl coenzyme A: cholesterol acyltransferase (ACAT) catalyzes the formation of intracellular cholesteryl esters in various tissues. Recently, human ACAT cDNA has been cloned and expressed in this laboratory (Chang, C.C., et al, 1993, Cheng, D.;...
This research has established feasibility of surface temperature characterization using ruby fluorescence. Study was performed in pin-on-disk geometry, with balls made of different plastics sliding against the sapphire disk. Fluorescence signal was...
Cytokinins regulate broad aspects of plant growth and development, such as cell division, root and shoot growth, chloroplast development, and leaf senescence. Cytokinins are perceived by a signal transduction pathway that involves receptors,...
The pain that follows nerve injury is chronic and consistently refractory to available analgesics. Neuropathic pain syndromes include deafferentation pain, diabetic, cancer and ischemic neuropathies, phantom limb pain, trigeminal neuralgia,...
NIMA-related kinases (Neks) control several aspects of cell division downstream of master mitotic regulators such as Cdk1 and Plk1. Though depletion of Nek6, Nek7, or Nek9 results in cytokinesis failure, to date no molecular mechanism has been...
This dissertation explores the spatial and temporal distributions of impurities in natural ice. Using polarized light, ion chromatography (IC), synchrotron x-ray topography (SXT), scanning electron microscopy (SEM), and energy-dispersive...

We present designs, theory and the results of fabrication and testing for a novel parallel microrobotic assembly scheme using stress-engineered MEMS microrobots. The robots are 240-280 μm × 60 μm × 7-20 μm in size, each robot consist of a...
