Operant Conditioning Systems
When you see a child throwing a toy, you may immediately think of a way to punish him. Then, you may reward him with a token or another prize if he does so. However, if he continues to do so, he will get punished and miss out on the activity. This is an example of operant conditioning in action. When a child learns an association between a behavior and a consequence, they become less likely to repeat the same behavior. Similarly, the salience of a consequence and the frequency with which a child receives reinforcement are important factors in speeding up this process.
A common design for an operant conditioning chamber is a headport clamp and a movable objective microscope. The latter was mounted over an air table. The TPM included two objectives: a 40x water immersion objective and a 40x 0.6 NA with correction collar. The two illumination sources used in the TPM were a Ti:Sapphire laser and a Chameleon Ultra II light. The camera setups were designed to fit onto the barrel of the water immersion objective.
The most important aspect of the operant conditioning chamber is the use of infrared cameras. These cameras enable researchers to observe subjects in complete darkness. IR-sensitive cameras are used in the process because they do not affect the animal's condition. The wide field of view of the infrared light is especially useful in these conditions. Moreover, the operating space in isolation cubicles is very limited, so it is best to buy a camera that is designed to fit in there.
The operant conditioning chambers are usually located in isolation cubicles. The protocols require that there is no visible light in the room. The cameras must therefore have infrared illumination. The IR-sensitive cameras also have a wide field of view, making them ideal for use in this environment. Because the cameras used for operant conditioning are small, they are best suited for use in these environments. The aim of this research was to develop the neural network to predict a behavior.
The system allows detailed analysis of animal interactions and the reinforcement they receive. It also provides detailed log files. Although these systems are not suitable for head-mounted devices, they provide comprehensive data about animal behavior. While they are capable of tracking movement in the head, they cannot accurately describe the position of an animal. They are not suitable for interpreting the results of in-vivo experiments. They do not have a clear purpose. The main objective of these studies is to understand the mechanisms of learning in animals.
The Psibox automated operant conditioning system consists of three modules: a central control unit, a water delivery system and an operant interface for a home cage. The central control unit has a custom PCB board and National Instruments OEM USB-6211 (NI6211) data acquisition board. The cost of the Psibox is $1,000 per cage. This device can be connected to a computer by a USB 2.0 cable.
An operant conditioning system records instances of a behavior and provides detailed log files. These systems can only describe behaviors that directly trigger the sensors. The system cannot record the positions of animals. Nonetheless, the systems can be extremely effective in training animals. The best thing about the PsiO2P is that it allows you to analyze animal interaction in real time. This is a great help in assessing the behaviors of animals and making decisions.
The Psibox is a small video camera that records each trial. The video captured by the Psibox is one of the best examples of an operant conditioning system. The camera is an excellent supplement to the standard analysis of data logs. So, if you're interested in learning how to train a mouse, consider the Psibox. It has many advantages for the experimenter and enables him to train thousands of mice at a time.
In a traditional operant conditioning system, a camera records the top view of the chamber. Individual timestamps are recorded for every instance during the active phase of the protocol. The Psibox displays details of individual trials, such as the position of the cued opening. This allows you to record the behavioral outcomes of a large number of mice. Hence, it is a highly effective experimental method to measure the effects of different treatments on animal behavior.
