The illustration depicts a typical setup for a rodent behavioral experiment, often used in neuroscience and behavioral studies. This apparatus is used to administer shocks or to measure responses to stimuli such as light or sound. The setup consists of two vertical cylindrical towers with horizontal bars and paddles flanking a central platform where a rodent can be placed. The materials are primarily in white, tan, and brown colors. This type of setup is common in experiments that investigate learning, memory, and fear conditioning.
