The Y maze is similar to the T maze, except with three arms at 120 degrees to each other. The rodent or mouse starts at the end of one arm, then chooses between the other two. Spontaneous alternation is measured to demonstrate learning.
The Y-maze is often preferred to the T-maze because gradual turns decrease learning time as compared to the sharp turns of the T-maze. It is also a smaller maze* to allow fewer degrees of freedom of movement, focusing the animal on the task at hand. The Y Maze can also be baited with food for rewarded alternation. Food wells are standard 1cm deep.
The Standard Manual Stereotaxic Instrument is important equipment in the fields of neuroanatomy, neurophysiology, neuropharmacology, and neurosurgery. It uses the marks on the surface of the skull (such as the bregma point) as the basic reference point to determine a certain subcortical layer of the animal through three-dimensional movement. The location of the nerve structure (nucleus), and then complete the directional injection, stimulation, destruction, guidance, and positioning of the nerve structure. It can be used to establish animal models of Parkinson’s disease, animal models of epilepsy, brain tumor models, and learning, research on memory, neural stem cell transplantation in the brain, cerebral ischemia, etc. This is the Manual version of the Digital Stereotaxic Instrument for Rat.
