Fear conditioning in invertebrates
Learning to identify and predict threats is a basic skill that allows animals to avoid harm. Studies in invertebrates like Aplysia californica, Drosophila melanogaster, and Caenorhabditis elegans have revealed that the basic mechanisms of learning and ...

Desensitization and Fear Conditioning
Varied numbers of electroshock administrations followed by equal numbers of CS-UCS paired presentations were given to 7 groups of male albino rats to study desensitization and fear conditioning. Conditioned fear R, measured by the obstruction apparatus, was weaker in rats shocked prior to fear conditioning.

Serotonergic Modulation of Conditioned Fear [PDF]
Conditioned fear plays a key role in anxiety disorders as well as depression and other neuropsychiatric conditions. Understanding how neuromodulators drive the associated learning and memory processes, including memory consolidation, retrieval/expression,

Contextual Fear Conditioning in Zebrafish [PDF]
Abstract Zebrafish are a genetically tractable vertebrate that hold considerable promise for elucidating the molecular basis of behavior. Although numerous recent advances have been made in the ability to precisely manipulate the zebrafish genome, much less is known about many aspects learning and memory in adult fish.

Extinction in Human Fear Conditioning [PDF]
Although most extinction research is conducted in animal laboratories, the study of extinction learning in human fear conditioning has gained increasing attention over the last decade. The most important findings from human fear extinction are reviewed in this article.

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]
Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

Enhanced Instructed Fear Learning in Delusion-Proneness
Psychosis is associated with distorted perceptions and deficient bottom-up learning such as classical fear conditioning. This has been interpreted as reflecting imprecise priors in low-level predictive coding systems. Paradoxically, overly strong beliefs,

The NMDA agonist D-cycloserine facilitates fear memory consolidation in humans [PDF]
Animal research suggests that the consolidation of fear and extinction memories depends on N-methyl D-aspartate (NMDA)- type glutamate receptors.

Generalization gradients for fear and disgust in human associative learning
Previous research indicates that excessive fear is a critical feature in anxiety disorders; however, recent studies suggest that disgust may also contribute to the etiology and maintenance of some anxiety disorders.
