The anatomical organization of the connections of the major components of the basal ganglia was investigated in detail. A sensitive procedure for the simultaneous study of afferents and efferents was carried out on the striatum (CP), globus pallidus (GP), and substantia nigra (SN). Previously well characterized connections of the CP were confirmed, additional evidence for a projection to the CP from the ventromedial nucleus of the thalamus was obtained and a topographically organized projection to the CP from the GP was discovered. A similar study of the SN revealed a nigral projection to the ipsilateral lateral dorsal nucleus of the thalamus and nigral input from the contralateral posterior lateral hypothalamus. The projection of the GP to the SN was found to be linked topographically to the striatonigral and pallidostriatal pathways. A study of the connections of the GP confirmed a massive projection from the CP and provided further evidence of a reciprocal connection. In addition, pallidal innervations of the entopeduncular nucleus and reticular nucleus of the thalamus were indicated. Because of the potential importance of a pallidostriatal projection and the significant number of technical difficulties associated with its demonstration, additional experiments were carried out to confirm the presence of this pathway and to determine its anatomical relationship to other basal ganglia connections. Retrograde labelling of pallidostriatal neurons, studied with electron microscopy and in combination with lesions of the striatum, confirmed that pallidal neurons project either to or through the striatum. Evidence for possibly two groups of pallidal neurons that project to the CP was obtained, and it was observed that both of these cell groups were congruent with the striatopallidal terminal fields. Comparisons of the distribution of cells retrogradely labelled after tracer injections into the cortex and CP in combination with histochemistry for acetylcholinesterase demonstrated that the population of pallidal neurons projecting to the CP was distinct from that of peripallidal cholinergic neurons which may project through the striatum to the cortex. Double retrograde fluorescent tracing experiments indicated that pallidal neurons which project to the CP also have collateral projections to the substantia nigra and perhaps to the subthalamic nucleus. The application of a new technique for studying, efferent projections allowed the confirmation and morphological description of the projection of the globus pallidus to the striatum. The characteristic morphology of this projection was shared by pallidal efferents which project to the entopeduncular nucleus, the reticular nucleus of the thalamus, the subthalamic nucleus and the substantia nigra. The fine morphological detail afforded by this method of anterograde tracing was utilized in combination with a histochemical protocol to show that pallidostriatal terminals end in part on somatostatin-containing neurons in the CP. / Graduate and Postdoctoral Studies / Graduate

Biochemical, anatomical, and histochemical studies were performed in the basal ganglia with an emphasis on the localization of the enzyme acetylcholinesterase (AChE). The existence of the enzyme in dopaminergic nigro-striatal neurons was demonstrated. Descending striato-nigral and pallido-nigral axons did not contain detectable amounts of AChE. A cell group called the nucleus basalis magno-cellularis, intimately associated with the globus pallidus, was found to contain high levels of AChE; furthermore, these neurons were shown to be the source of a cholinergic projection to the neocortex. In the striatum, large neurons containing high levels of AChE were found to be likely candidates as..the cholinergic neuron of the striatum. Cholinergic perikarya were found to be absent in the neocortex; nor were perikarya synthesizing large amounts of AChE found in the neocortex. An empirical hypothesis was formulated on the basis of these and other findings regarding cholinergic neurons: High levels of AChE are a necessary but not sufficient criterion for identifying cholinergic perikarya. / Graduate and Postdoctoral Studies / Graduate

The primary purpose of the study was to determine if measured LBM could be used as a more powerful predictor of BMR than could surface area (SA) as calculated by the formula of DuBois and DuBois (1916). It was also of interest to develop a prediction equation for BMR using multiple regression analysis. Data from 82 women and 76 men were included in the study. Pearson product-moment correlations indicated that LBM was a better predictor for BMR than SA on either of the principal SA prediction equations, those of Aub and DuBois (1917) and Harris and Benedict (1919). Age, sex, and fat weight were not found to contribute significantly to prediction when included by multiple regression analyses. Linear equations for BMR as a function of LBM were developed for each sex. Tables based on these equations were also generated as a quick reference for clinicians.

This thesis discusses the effects of basal friction and basement configuration on the deformation of the fold-and-thrust belts in convergent zones. A series of analogue models were conducted with adjacent different basal configuration and frictional properties to observe and gain a better understanding of these basal effects and their interactions. The results from these side-by-side systematic models demonstrate that the kinematics and geometry of the deformation wedges are strongly influenced by the mechanical and geometrical basal effects. In these experiments, high accuracy laser scanner and digital camera were used to record the evolution of the surface topography of the deformed sand packs. Comparison between models with different basal friction shows that the basal friction plays a significant role on the propagation and topography of the deformation structures in aspects such as wedge height, taper angle, number of imbricates and deformation front. The models with a basal viscous material, which acts as low friction substrate, illustrates that the propagation of deformation above viscous material is faster and further than above the adjacent mechanically different frictional decollement. In the experiments with a moving plate under the part of the sand pack, the velocity discontinuity was introduced by either rigid, i.e. frontal edge of the metal plate, or deformable like distal end of the viscous materials. The results of these kinds of experiments, applicable to for example basement faults, salt decollements and tectonic underplating simulations, illustrate that the deformation localizes and develops continuously above the velocity discontinuities. Besides, the different rate and distance of the propagation of deformation fronts caused by different substrate distribution between the adjacent zones also lead to the formation of transpressive zones at the boundary of these adjacent domains with different basal friction/configurations.
