Fear Conditioning

JoVE Science Education

Fear Conditioning is a type of learning in which an association is established between a negative unpleasant event and a harmless stimulus. This leads to a fear of the harmless stimulus. This process is largely mediated by the amygdala, which is a brain region involved in emotions and stress reactions. Fear conditioning can be utilized in several ways to understand different aspects of learning and memory. This video presents an overview of the principles behind fear conditioning, discusses the equipment and a generalized procedure used for this type of experiment. Finally, we'll review some real world applications of fear conditioning in behavioral neuroscience research today.

An Introduction to Learning and Memory

JoVE Science Education

Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common terminologies and a brief outline of concepts in this field. Then, key questions asked by behavioral scientists and prominent tools such as fear conditioning and fMRI are discussed. Finally, actual experiments dealing with aging, eradication of traumatic memories, and improvising learning are reviewed.

Positive Reinforcement Studies

JoVE Science Education

Researchers study learning of a behavior through the use of operant conditioning. This type of learning involves associating the behavior with a consequence, which is a reward or punishment. If the consequence is a reward, it leads to reinforcement of the desired behavior. One type of reinforcement approach is positive reinforcement, where the behavior is rewarded with an artificial, natural, or social reinforcer. Studies using positive reinforcement as a tool can help tease out important details about neurological functioning associated with different behaviors. This video reviews the concepts behind reinforcement studies by using an example of a man training a dog to sit. Following this, we look at a generalized procedure of positive reinforcement commonly used by behavioral researchers. This involves, training rodents to perform a behavior (lever press) to get a reward (food). Lastly, specific applications demonstrate how scientists use positive reinforcement to understand behavior.

An Introduction to Reward and Addiction

JoVE Science Education

Consequences play a major role in controlling our behavior. If the consequence is a reward, then it encourages the associated behavior. Rewards can come in many forms such as a pleasant feeling, money, or food. However, sometimes an individual engages in compulsive behavior despite of negative consequences, and this state is known as addiction. Administration of addictive substances is neurochemically rewarding, which ultimately causes a loss of control in limiting the intake. Scientists aim to better understand the mechanisms behind these concepts and subsequently develop new therapies for treating substance abuse disorders. JoVE's introduction to reward and addiction explains the neuroanatomical components of the reward pathway. This is followed by some of the important questions asked by behavioral researchers such as how does our brain chemistry change in response to drug use. Prominent methods section reviews some of the tools being employed in the field, like self-administration protocols. Finally, the video discusses example experiments conducted in labs interested in investigating reward and addiction.

JoVE 50189

In animals with large identified neurons (e.g. mollusks), analysis of motor pools is done using intracellular techniques1,2,3,4. Recently, we developed a technique to extracellularly stimulate and record individual neurons in Aplysia californica5. We now describe a protocol for using this technique to uniquely identify and characterize motor neurons within a motor pool.

An Introduction to Behavioral Neuroscience

JoVE Science Education

Behavioral neuroscience is the study of how the nervous system guides behavior, and how the various functional areas and networks within the brain correlate to specific behaviors and disease states. Researchers in this field utilize a wide variety of experimental methods ranging from complex animal training techniques to sophisticated imaging experiments in human subjects. This video first offers a historical overview of some of the major milestones that lead to our current understanding of the brain’s control over behavior. Then, some of the fundamental questions asked by behavioral neuroscientists are presented, which all involve the study of neural correlates, or specific brain regions whose activation is responsible for a given function. Next, prominent methods used to answer those questions are reviewed for both human and animal subjects, such as operant conditioning and functional neuroimaging. Finally, experimental applications of these techniques are presented, including animal training using a Skinner box, and the use of electroencephalography to investigate human neurological disease.

Self-administration Studies

JoVE Science Education

Behavioral reinforcement induced by the rewarding feelings following substance use sometimes leads to addiction, which is demonstrated by increased self-administration. Drug self-administration studies in rodents model human behavior during drug abuse. These models are useful in understanding the neurobiological behavior of addiction in order to help scientists discover new treatments for drug dependence. This video reviews the concepts underlying self-administration studies. A general protocol of self-administration is discussed, which includes description of necessary equipment and different routes of administration commonly employed. Some modified protocols used to model more complex aspects of addiction, such as progressive ratio schedule and extinction, are also explained. Finally, experiments conducted in current addiction research labs will be examined.
