ABSTRACT
1. In the brain of Salmo gairdneri, the content of dopamine (DA), norepinephrine (NE), serotonin (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) depends upon the location in the brain (hypothalamus, telencephalon or mesencephalon). 2. The origin of feed protein (from animal or vegetal origin) influences the level of the various monoamines studied in different brain structures. 3. Hypoxia (60% oxygen saturation in water) causes modifications of 5-HT and catecholamine (DA, NE) contents in different brain structures, depending upon the diet.

We report the development of an electrooptic cell consisting of a cylindrical sample of Z-cut KD*P with a ring-electrode geometry for applying voltage to the crystal. Theoretical analysis and experimental results demonstrate that this cell design results in high transmission uniformity across the cell aperture and subnanosecond switching capability. Compared with cell of conventionaldesign, the new cell permits an order-of-magnitude improvement in transmission uniformity as well as improved switching speed.
