But crucial information was missing and this keeps the public in the dark about tax avoidance.
Depending on the cognitive test, this may be the time it takes an animal to escape to a hidden platform (water maze), an escape tunnel (Barnes maze) or to enter a dark component (passive avoidance test).
"We have been copying what bats are doing in terms of echolocation for navigation in the dark and collision avoidance".
Risk factors for low vitamin D levels include older age, living in northern latitudes, sun avoidance, dark skin pigmentation, obesity, low dietary intake of vitamin D, and various medical conditions, especially malabsorption syndromes.
We believe that the lack of these cues makes the cLDB a better instrument to measure light avoidance or dark preference than the light-dark boxes normally used in rodent studies (see also [ 94]).
It also decreased step-through latency and increased time spent in the dark side of passive avoidance task.
Borage treatment improved step-through latency and time spent in dark compartment in passive avoidance tasks.
The results showed that A β (25 35) impaired step-through latency and time in dark compartment in passive avoidance task.
Casing the galleries, I was struck by this wilful avoidance of darker, pressing realities.
Tadpoles have a natural tendency to avoid dark moving dots, and the researchers exploited this by putting some tadpoles into a Petri dish, showing them dark dots under various lighting conditions, while using specially designed video-tracking software to track the movements of the tadpoles and the dots, and to measure the tadpoles' avoidance responses.
Because the latency is not affected by activity or freezing of mice, memory retention is evaluated by the avoidance of the dark compartment where the footshock was delivered to the mice.
