Our findings indicate that preattentive processes, such as the filling in of homogeneously colored areas, discrete dots, or bars across the blind spot, take into account both the color and the form that stimulate the retina around the optic disk. Perceptual completion of the "junction" of two opposite colors facing each other on opposite sides of the blind(More)
In our work we present techniques for illustrative rendering of interpreted seismic volume data by adopting elements from geology book illustrations. We also introduce combined visualization techniques of interpreted and uninterpreted data for validation, comparison and interdisciplinary communication reasons. We introduce the concept of smooth transitions(More)
Using a chronic stress model of depression, the biochemical, hormonal, and neurochemical effects of chronic stress were determined in male CD-1 mice. The effects of chronic administration of three tricyclic antidepressants (TCA): chlorimipramine, amitriptyline and desmethylimipramine, as well as fluoxetine, a specific serotonin uptake inhibitor, were also(More)
The effects of fusaric acid (FA), a dopamine-beta-hydroxylase (D beta H) inhibitor, were determined on aggression, motor activity, and brain monoamines at doses of 3.2 to 60 mg/kg following administration of dietary supplements of L-tyrosine or balanced protein to male albino mice. Compared to saline injected control animals, both aggression and motor(More)
This study examined the interaction of dietary tryptophan (TRP) and differential housing on territorial-induced aggression, locomotor activity, and monoamine neurochemistry in mice. Groups of male CF-1 mice were singly-housed or group-housed and administered a semisynthetic basal diet supplemented with TRP (0.25-1.0%). Behavioral measures were taken at(More)
We present a toolbox for quickly interpreting and illustrating 2D slices of seismic volumetric reflection data. Searching for oil and gas involves creating a structural overview of seismic reflection data to identify hydrocarbon reservoirs. We improve the search of seismic structures by precalculating the horizon structures of the seismic data prior to(More)
Proximal spinal muscular atrophy (SMA), one of the most common genetic causes of infant death, results from the selective loss of motor neurons in the spinal cord. SMA is a consequence of low levels of survival motor neuron (SMN) protein. In humans, the SMN gene is duplicated; SMA results from the loss of SMN1 but SMN2 remains intact. SMA severity is(More)
Drug treatments which influence brain serotonergic systems were administered to lactating female mice during the early postpartum period, and their effects on aggressive behavior, locomotor activity and brain monoamines were examined. P-chlorophenylalanine (200 and 400 mg/kg) and 5-hydroxytryptophan (100 mg/kg) inhibited fighting behavior of postpartum mice(More)
A method was developed for producing and measuring territorial aggression in male CF-1 laboratory mice using a simple apparatus. The technique is based on data collected from approximately 1000 CF-1 mice in order to establish the parameters and optimize the procedures. In this technique the mouse takes up lone residence for 24 hr in a 60 cm square box(More)
