The Raspberry Pi Digital Actuality system (PiVR) is adaptable software for performing digital reality environments to tiny, freely shifting animals. The practice of PiVR, along with procedures like optogenetics, will promote the mapping and characterization of neural circuits involved in the conduct.PiVR comprises of a behavioral environment, a digital camera, a Raspberry Pi microcomputer, an LED controller, and a touchscreen. This method can perform a suggestions loop between real-time behavioral monitoring and supply of a stimulus. With the help of PiVR, researchers are hoping to make digital actuality paradigms convenient to everybody, from skilled experts to students.
