y maze

The y maze has been widely used in research on spatial memory and learning for several decades, starting from the 1940s. The y maze test on rodents has helped understand a wide range of neurological and psychiatric conditions in humans, including aging, Alzheimer's disease, schizophrenia, and depression. It has also been used to evaluate the effects of drugs, such as antidepressants and cognitive enhancers on spatial working memory.

The y maze consists of three arms, arranged at angles of 120 degrees each in the shape of a "Y". The y maze has a start arm, a goal arm, and a choice arm. The rodent is placed in the start arm and allowed to explore the maze for a set time.

The working of the VJ Instruments y maze is as follows. The rodent is placed in the center of the maze and is monitored by a MazeMaster video tracking application through a camera that is fixed directly above the maze. The software automatically calculates and analyzes parameters related to learning and memory, such as the time needed to reach the reward arm and the number of entries into each arm. The MazeMaster software analyzes the video and parameters like the number of entries to each arm, distance traveled, time spent in each arm, and more. The trajectory of the movement provided by MazeMaster software helps to analyze the movement of the rodent.

The VJ Instruments y maze is available in any custom color. The Y-Maze comes in as a part of the whole package that includes the licensed MazeMaster video tracking software, a camera with accessories like cables fixing, IR lights, Light fixtures, and a PC. The same package can be used to perform tests on a variety of other mazes manufactured by VJ Instruments, like Y-Maze, T-Maze, Radial-Maze, Morris water maze, Barnes maze, Elevated Zero Maze, Open field Maze, and more.

Elevated Plus Maze (EPM)

The elevated plus maze (EPM) is a commonly used behavioral test in rodents to study anxiety-like behavior and its modulation by drugs, hormones, and genetic manipulations. The elevated plus maze consists of a central platform elevated above the floor, with two open arms and two closed arms in a 'plus' shape. The open arms have no walls and the closed arms have walls on three sides, creating a sense of confinement. The rodent is placed on the central platform and is allowed to freely explore the maze. The elevated plus maze is a relatively simple and cost-effective way to study anxiety-like behavior in rodents. It has been used in a wide range of studies on the neural and molecular mechanisms underlying anxiety. It has also been used to evaluate the efficacy of anxiolytic drugs, which are drugs that reduce anxiety.

The VJ Instruments’ Elevated plus maze is manufactured using high-end non-reflective material and is available in any custom color. The elevated plus maze comes in as a part of the whole package that includes the licensed MazeMaster video tracking software, a camera with accessories like cables fixing, IR lights, Light fixtures, and a PC. The same package can be used to perform tests on a variety of other mazes manufactured by VJ Instruments, like the Radial maze, T-Maze, Y-Maze, Morris water maze, Barnes maze, Elevated Zero Maze, Open field maze, and more.

This is how the VJ Instruments elevated plus maze functions. The rodent is placed in the center of the maze facing towards the open arm, and is allowed to freely explore the maze for 5 minutes. The rodent is observed by a camera mounted above the open field maze. The camera is connected to a PC where the MazeMaster software is installed. The time spent and frequency of entries into open and closed arms is recorded with VJ Instruments MazeMaster software by analyzing the video. Other parameters that are recorded by the software are latency to the first arm, total time spent, distance traveled in open and closed arms, total distance traveled, and more.

VJ Instruments supplies a wide range of pharmaceutical equipment, more than just mazes those study animal behaviors. VJ Instruments supplies R&D equipment, transdermal patch machines, behavior instruments, clinical instruments, and more. For example, VJ Instruments provides R&D machines like pelletizing machines, which include every pelletizing machine like spheronizers, Holt melt excluders, die roll extruders, and screw extruders.

A pelletizing machine is a type of equipment used in the pharmaceutical industry to convert powder or granular materials into small, cylindrical pellets. These pellets are typically used for the production of tablets and capsules and can also be used for other forms of drug delivery such as oral, nasal, and pulmonary delivery.

A pelletizing machine has different types, including single-screw extruders, twin-screw extruders, and rotary drum pelletizers. Each type has its own unique advantages and disadvantages, and the choice of machine will depend on the specific application and the type of material being processed.
