Lesions were placed in various parts of the inferior olivary nucleus and olivocerebellar tract in an attempt to define further the role of the inferior olive in the performance of a conditioned limb-flexion response (LFR) in cats. Thirty-two cats were trained to make an LFR using either classical or instrumental conditioning. The conditioned stimulus (CS) was a tone, and the unconditioned stimu...

Title of Document: RELIABILITY EVALUATION OF LIQUID AND POLYMER ALUMINUM ELECTROLYTIC CAPACITORS 45BAnshul Shrivastava, Doctor of Philosophy (Ph.D.), 2014 Directed By: Professor Michael Pecht, Department of Mechanical Engineering Liquid aluminum electrolytic capacitors are known for their reliability problems. They are considered as the weakest link in the power electronics system. The liquid e...

We studied the effect of bilateral electrolytic lesions in the medulla oblongata on the cerebral ischemic reflex in 24 anesthetized rabbits. In IS animals lesions were placed in areas from which the differentiated vasomotor component of the response was elicited by electrical stimulation. In four rabbits (group A) the lesions entirely abolished the vasomotor, but not cardiac responses to cerebr...

I t has been recognised that a major factor which affects the current efficiency in the commercial electrolytic cells for magnesium is the wettability of the cathode surface with respect to magnesium and the ability of the metal deposited to grow into a considerable size on cathode surface before getting released from it. Factors affecting these and studies to improve the wettability have alrea...

plasma electrolytic oxidation (peo) is the new, environmentally and cost-effective method for coating the metals. this method vastly has been studied for coating aluminum, titanium and magnesium and their alloys and recently for steel. in present study, ck45 steel samples were coated by peo method in order to improve corrosion resistance. during this process specimens were immerged in carbonate...

Little is known regarding the descending inhibitory control of genital reflexes such as ejaculation and vaginal contractions. The brainstem nucleus paragigantocellularis (nPGi) projects bilaterally to the lumbosacral motoneuron pools that innervate the genital musculature of both male and female rats. Electrolytic nPGi lesions facilitate ejaculation in males, leading to the hypothesis that the ...

We compared the mean arterial pressure and heart rate activity of conscious, unrestrained rats during 1-hour and 24-hour continuous recording sessions, 3 to 4 weeks after either sinoartic denervation, placement of electrolytic lesions in the nucleus tractus solitarii, or sham operations. Sinoaortic denervation and nucleus tractus solitarii lesions both eliminated the reflex bradycardia to a phe...

The ability of 17 cats to discriminate floor temperatures 2-4 degrees C below the ambient temperature was tested before and after unilateral electrolytic thalamic lesions. The lesions were made contralateral to the paws showing better performance in the temperature discrimination task. They were aimed at one or more of the three main target areas of thermoreceptive-specific lamina I spinothalam...

The present study is part of an ongoing series of experiments aimed at delineation of the neural pathways that mediate fear-potentiated startle, a model of conditioned fear in which the acoustic startle reflex is enhanced when elicited in the presence of a light previously paired with shock. A number of cortical areas that might be involved in relaying information about the visual conditioned s...
