Local brain tissue oxygen tension, temperature, and electrical potential were continuously and simultaneously measured at each of two different depths in anesthetized, paralyzed rat brain. Brain tissue temperature increases up to 1 degree C were recorded in response to direct electrical stimulation, spreading depression, PTZ-induced seizures, hypercapnia,(More)
Diabetes is a disease which occurs when the pancreas does not secrete enough insulin or the body is unable to process it properly. This disease affects slowly the circulatory system including that of the retina. As diabetes progresses, the vision of a patient may start to deteriorate and lead to diabetic retinopathy. Diabetic retinopathy is most common(More)
Vibration of a smart beam is being controlled. This smart beam setup is comprised of actuators and sensors placed at the root of a cantilever beam. Vibrations can be caused by various sources including human activity and nearby motorized equipment. In this case, disturbance is produced using a white noise signal to the actuator. The piezoelectric sensors(More)
We characterized the electrophysiological properties and responses of neurons located in the parapyramidal region of the ventral aspect of the rat medulla oblongata (parapyramidal neurons, PP neurons) to oxygen deprivation, in order to understand the mechanisms involved in hypoxia induced respiratory depression. The responses of PP neurons to oxygen(More)
The effects of low dose ethanol treatment on neuronal firing threshold were studied in dentate granule neurons using intracellular recording. A higher threshold for orthodromic activation and lower threshold for somatic activation were observed in 50 mM of ethanol, based on an examination of the excitatory postsynaptic potentials, strength duration and(More)
— The bandwidth of the wireless signals been separated by means of channels and are sent to the base station for Transmission and reception in wireless communications. Each channel is of different frequency and the corresponding transmitter and receiver are able to identify the signals of the respective channel without any noise. To design a basic multiple(More)
