The Role of Nucleus Accumbens Shell in Learning about Neutral versus Excitatory Stimuli during Pavlovian Fear Conditioning
Peer reviewed Peer reviewed
Direct linkDirect link
Bradfield, Laura A.; McNally, Gavan P. – Learning & Memory, 2010
We studied the role of nucleus accumbens shell (AcbSh) in Pavlovian fear conditioning. Rats were trained to fear conditioned stimulus A (CSA) in Stage I, which was then presented in compound with a neutral stimulus and paired with shock in Stage II. AcbSh lesions had no effect on fear-learning to CSA in Stage I, but selectively prevented learning…

A Layered Network Model of Associative Learning: Learning to Learn and Configuration.
Peer reviewed Peer reviewed
Kehoe, E. James – Psychological Review, 1988
A detailed description of a layered network model is provided, with computer simulations of key associative learning phenomena and predictions generated from the model. The model is compared to more conventional theories of learning to learn and configural learning. (SLD)
