Contextual fear conditioning in humans: cortical-hippocampal and amygdala contributions.
Functional imaging studies of cued fear conditioning in humans have mostly confirmed findings in animals, but it is unclear whether the brain mechanisms that underlie contextual fear conditioning in animals are also preserved in humans. We investigated this issue using functional magnetic resonance imaging and virtual reality contexts. Subjects underwent differential context conditioning in whi...
متن کاملContextual fear conditioning in humans using feature-identical contexts
Contextual fear conditioning studies in animals and humans found an involvement of the hippocampus and amygdala during fear learning. To exclude a focus on elements of the context we employed a paradigm, which uses two feature-identical contexts that only differ in the arrangement of the features and requires configural processing. We employed functional magnetic resonance imaging to determine ...
متن کاملImpaired fear conditioning following unilateral temporal lobectomy in humans.
Classical fear conditioning was used in the present study as a model for investigating emotional learning and memory in human subjects with lesions to the medial temporal lobe. Animal studies have revealed a critical role for medial temporal lobe structures, particularly the amygdala, in simple and complex associative emotional responding. Whether these structures perform similar functions in h...
متن کاملExtending animal models of fear conditioning to humans.
A goal of fear and anxiety research is to understand how to treat the potentially devastating effects of anxiety disorders in humans. Much of this research utilizes classical fear conditioning, a simple paradigm that has been extensively investigated in animals, helping outline a brain circuitry thought to be responsible for the acquisition, expression and extinction of fear. The findings from ...
متن کاملContextual fear conditioning in zebrafish.
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 of learning and memory in adult fish. Here, we describe the development of a contextual fear conditioning paradigm using...
