The Basolateral Amygdala: The Core of a Network for Threat Conditioning, Extinction, and Second-Order Threat Conditioning

Biology, 2023
Threat conditioning, extinction, and second-order threat conditioning studied in animal models provide insight into the brain-based mechanisms of fear- and anxiety-related disorders and their treatment.

The Opioid Receptor Antagonist Naloxone Enhances First-Order Fear Conditioning, Second-Order Fear Conditioning and Sensory Preconditioning in Rats

Frontiers in Behavioral Neuroscience, 2021
The opioid receptor antagonist naloxone enhances Pavlovian fear conditioning when rats are exposed to pairings of an initially neutral stimulus, such as a tone, and a painful foot shock unconditioned stimulus (US; so-called first-order fear conditioning;

Early Auditory Event Related Potentials Distinguish Higher-Order From First-Order Aversive Conditioning

Frontiers in Behavioral Neuroscience, 2022
Stimuli in reality rarely co-occur with primary reward or punishment to allow direct associative learning of value. Instead, value is thought to be inferred through complex higher-order associations.

Understanding Associative Learning Through Higher-Order Conditioning

Frontiers in Behavioral Neuroscience, 2022
Associative learning is often considered to require the physical presence of stimuli in the environment in order for them to be linked. This, however, is not a necessary condition for learning.

Explicit and Implicit Processes in Human Aversive Conditioning [PDF]

, 2006
The ability to adapt to a changing environment is central to an organism’s success. The process of associating two stimuli (as in associative conditioning) requires very little in the way of neural machinery.

Higher-Order Conditioning With Simultaneous and Backward Conditioned Stimulus: Implications for Models of Pavlovian Conditioning

Frontiers in Behavioral Neuroscience, 2021
In a new environment, humans and animals can detect and learn that cues predict meaningful outcomes, and use this information to adapt their responses. This process is termed Pavlovian conditioning.

Higher-Order Conditioning and Dopamine: Charting a Path Forward

Frontiers in Behavioral Neuroscience, 2021
Higher-order conditioning involves learning causal links between multiple events, which then allows one to make novel inferences. For example, observing a correlation between two events (e.g., a neighbor wearing a particular sports jersey), later helps ...

Second-order associative memory circuit hardware implemented by the evolution from battery-like capacitance to resistive switching memory

iScience, 2022
Summary: Memristor-based Pavlov associative memory circuit presented today only realizes the simple condition reflex process. The secondary condition reflex endows the simple condition reflex process with more bionic, but it is only demonstrated in ...
