What does the Y maze test measure?

Y Maze Spontaneous Alternation is a behavioral test for measuring the willingness of rodents to explore new environments. Rodents typically prefer to investigate a new arm of the maze rather than returning to one that was previously visited.

How do you calculate Y maze?

The entry is considered when all four limbs are within the arm. The alternation percentage is calculated by dividing the number of alternations by number of possible triads x 100. The maze is cleaned with Virkon solution between animals to eliminate odor traces.

What is spatial working memory?

Spatial working memory entails the ability to keep spatial information active in working memory over a short period of time. To study the areas of the brain that are involved in spatial working memory, a group of stroke patients was tested with a spatial search task.

What type of memory does the Y maze test?

The Y-maze can be used to assess short term memory in mice. Spontaneous alternation, a measure of spatial working memory, can be assessed by allowing mice to explore all three arms of the maze and is driven by an innate curiosity of rodents to explore previously unvisited areas.

What is the role of the hippocampus in memory especially spatial memory?

The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting, though this is a matter of debate. It is also thought to play an important role in spatial processing and navigation.

Which type of memory is most impaired by damage to the hippocampus?

In all five experiments, patients with hippocampal damage exhibited impaired recognition memory.

What is the zero maze test?

The zero maze is used to test anxiety- and exploration-related behaviors in rats and mice. Again, the differences in time spent in the open and closed sections are measured and used as indication of anxiety versus exploration. …

Does the hippocampus store memory?

Hippocampus. The hippocampus, located in the brain’s temporal lobe, is where episodic memories are formed and indexed for later access.
