Discharge Patterns of Brain Stem Neurons During Saccadic and Pursuit Tracking Eye Movements.
Many visual processes are directly affected by eye movements. For example, if a visual target is to be viewed with maximum acuity, the eyes must be positioned so that the image of the object falls on the fovea, the retinal area with the greatest density of photoreceptors.

Effects of nicotine on content of corticotropin releasing factor (CRF) in rat amygdala, hypothalamus and brain stem
… anxiety, influences the same neurotransmitter systems as nicotine, a psychoactive component of tobacco. Radioimmunoassays revealed that in macro-dissected hypothalami, 15 minutes treatment with 1.0 mg/kg nicotine significantly increased CRF content compared to no treatment. The 1.0 mg/kg dose did …

Electrophysiologic detection of the neurotoxic effects of acrylamide and 2,5-hexanedione in rats
Brain stem auditory evoked potentials (BAEP) and somatosensory evoked potentials (SEP), recorded from subcutaneously placed electrodes in anesthetized rats, were used to detect the neurotoxic effects of acrylamide and 2,5-hexanedione. Sixty adult male rats were equally divided into four groups: …

The role of early management and hormone replacement therapy in potential heart and lung donors
… hormonal and inflammatory changes that follow brain stem death leads to donor organ injury. Appropriate donor management is essential to avoid further damage to already injured donor heart and lungs. Hormone replacement therapy with tri-iodothyronine and methylprednisolone in organ donors has …

Oxytocin as a pharmacological tool to curb overeating: Exploring synergy with opioid receptor blockade
… Though each of the many feeding-related neural systems affects the select facets of appetite to a different degree, most basic research (and subsequently, also clinical) studies exploring anorexigenic potential of neuroactive molecules, focus on targeting only one system. This single-system …

Respiratory function: A systems approach
… pontine respiratory center (MPRC) in the brain stem. The MPRC is responsible for generating the basic rhythm of breathing and corrects for disturbances. Neurons inside the MPRC are organized into a central pattern generator (CPG), the functionality of which is not clearly understood. …

Effects of dietary tyrosine and tryptophan supplementation on immunity and brain neurotransmitter levels after SRBC injections in chickens
… or tryptophan supplementation on immunity and brain neurotransmitter levels after antigen challenge. Chickens were given 0.1%, 0.5% or 1% supplemental dietary L-tyrosine or L-tryptophan prior to the injection of sheep red blood cells (SRBC). The 0.1% tyrosine supplementation increased primary …

Investigation of Capillary Stress Response in Connection With Anesthesia and Surgical Intervention
… anesthetic agent on the reticular activating system of the brain stem and the intraneuronal system of the cortex participate to an important degree in the production of anesthesia. | Briggs and co-workers state that as long ago as 1938 the distinguished British pharmacologist A.J. Clark, on …

Expression profile of multidrug resistance genes and proteins in cancerous and stem cells
… existence of a subpopulation of cells - cancer stem cells (CSCs) may be the major obstacle in treating gliomas. CD133 and nestin have been suggested as the markers of CSCs and natural stem cells. The primary focus of this study was to identify CD133+/nestin+ stem-like cells and discover their …

Brain distribution and release of Cholecystokinin octapeptide
… CCK₈ (iCCK₈) from rat central nervous system preparations and the regulation of this release have been studied. Rat brain was dissected into the following regions; hypothalamus, cerebral cortex, striatum and thalamus, according to the method of Brownstein, Arimura, Sato et. al. (1975). …

Analysis of early auditory evoked potentials elicited by stimuli with directional information
… correlate of spatial hearing in humans. Auditory brain stem responses (ABRs) and binaural difference potentials (BDs) to stimuli with interaural differences in time (ITD) and level (ILD) are measured and analyzed. In chap. 2 the advantage of using information from the raw data of a measurement to …

Short echo time single voxel magnetic resonance spectoscopy in the characterisation of childhood brain tumours.
INTRODUCTION Brain tumours are the most common solid tumour in childhood, while Magnetic Resonance Spectroscopy (MRS) studies have been performed on brain tumours previously, the majority have been performed on the adult patient population and at long echo times. The work presented in this thesis …
